BILmanager: => Club: !D!D GRIZZ on Defense - Teaching table now open - good defence wins tournaments - learn how - all welcome !D!D grizz: hi gang grizz: thx for attending another session on Defense grizz: we have talked about leads, third hand play and signals now for several months, and now i think it's time we put everything together grizz: so i will play against the robots today, choosing hands where EW declares, and make comments about leads, play, signals and whatever pops up grizz: and as always i encourage participation by all the kibs grizz: so jump right in with a comment, question, or bid at any time, but please do it in open chat grizz: since i can't always respond to private chat grizz: well now, that was spirited auction! grizz: now North must be thinking: EW bid to slam unopposed off 2 aces grizz: one of those must be dead, do i dare guess which one? PoorRich_1: grizz, do the gib's here bid revised 2/1? Dianne0516: I think the Robots drink oil with alcohol in it half the timegrizz: rofl grizz: i agree, and that's why i don't play money bridge any more :) grizz: the gibs play a form of basic 2/1, and you can click on their bids in the yellow box for description of their bids grizz: 4!h it says is a Help Suit Slam Try grizz: which I have never played, and cannot recommend grizz: i prefer cuebidding controls grizz: as slam tries grizz: and the first cuebid can be A, K, stiff or void grizz: so i would have bid 4!d as West grizz: and E would bid 4!h grizz: and nobody would know what the controls were without RKC to clarify grizz: nevertheless, the robots are in slam so what should we lead? grizz: hint: grizz: leading aces in this auction is suicide grizz: and underleading aces is worse grizz: so trump or !d grizz: the 'book' says lead aggressively vs. small slams grizz: so N opts for a !d grizz: NW are playing standard attitude signals, for purposes of this class grizz: but one does not signal with an honor in most cases grizz: here is another defensive rule - give count on declarer's lead grizz: lol as if W ruffing the trick weren't loud enough grizz: it doesn't pay for N to cover, since E can ruff grizz: and W might ruff anyway, playing S for the ace grizz: well, that was just a goofy slam grizz: but still, N should not double grizz: because of hands just like these, where one or even both aces gets ruffed out grizz: any questions on this one? grizz: besides the goofball auction? bookmarm: none, ty grizz: or was it? grizz: let's look at a Losing Trick Count analysis of the hand BILmanager: can't you do it without using GIB which is a cuase of huge confusion - sit in all 4 seats and use the randon deals ? ->BILmanager: i'm still only 50%, and that's too much thinking BILmanager: :) grizz: E's losers are: grizz: 2!s grizz: 1!d grizz: and 2!c grizz: 5 losers, which is a GF hand opposite any response, if a fit is found grizz: and for W: grizz: 2!s grizz: 1!h grizz: 1!d grizz: 2!c grizz: 6 losers TheMoak: 6 losers for west grizz: 6 + 4 = 10, and 24-10=14 grizz: so LTC predicts that EW will make 8!s, if they have enough controls gojoe: you have lost me grizz: bear with me, we will do Losing Trick Count another time grizz: or maybe now is good grizz: can we have a show of hands? grizz: who wants to do Losing Trick Count today? aljerry: yes Feegle->Club: where does +4 come from? BILmanager: say yea or nay doldridg->Club: yea aljerry: 6d 4sp gojoe: ok mildred42: i do HAFUN: yea annnew: yea grizz: ok, let's do LTC mildred42: yea grizz: LTC is a method for evaluating the strength of a hand BILmanager: !D 40 kibs I dont see 40 replies to Pete's question do you want to talk about LTC now ? doldridg: y jaldi: yea bookmarm: sure aljerry: y Dianne0516: y solidgold: y TALR: y gojoe: just do something right or wrong..taking too much time up juneber: y Gap56: y kopykat: Yes grizz: haven't seen any nays yet, so let's go forward grizz: LTC is an alternate method of hand evaluation MtlQueCan: you don't see any negative response so they must be positive grizz: different entirely from Milton point count grizz: let me first say that LTC only works well with a known fit grizz: and breaks down on balanced hands grizz: so disregard the method entirely on NT hands grizz: but here is the basic scheme grizz: look only at the top 3 cards in each suit grizz: so for the W hand, we look at the !SA76 grizz: for !hs, the KQ6 grizz: !d2 grizz: and !c42 grizz: the basic rule is, count 1 loser for each of those cards that is not an A, K or Q grizz: there will be some adjustments later, but let's start with the basics grizz: so for the W hand, the 7 and 6 are losers, for a count of 2 grizz: in !hs, only the 6 is a loser grizz: for a total count of 2+1=3 grizz: 1!d grizz: 2+1+1=4 grizz: and both the !cs are losers grizz: 2+1+1+2=6 grizz: so the W hand has 6 losers, with the known !s fit grizz: are we all clear on that part? Gap56: y joyable: y doldridg: y mildred42: y grizz: ok, let's look at the E hand grizz: the !SJT are losers, for 2 grizz: no losers in !h with the void grizz: the !d8 is a loser, for 2+1=3 jaldi: when in a tourney....does one have time to do the TLC grizz: yes, it takes less than 5 seconds to do it jaldi: and thinking of the bidding/auction? grizz: i do it on all hands, as a cross-check grizz: in fact, sometimes i do several different evaluations grizz: Milton point count grizz: LTC grizz: Rule of 20 grizz: and Zar Points gojoe: actually the king of clubs is on right side of ace..for one trick joyable: ? smudge1->Club: zar? joyable: zar lanor fow: complicated point count grizz: for real bridge geeks, check it out on Wikipedia grizz: thumbnail sketch of Zar Points: grizz: formulated by Zar Petkov, after long and industrious statistical evaluation of bidding systems grizz: A=6 points grizz: K=4 grizz: Q=2 grizz: J=1 gojoe: are you sure we are beginners/intermediate grizz: i don't expect you to remember or use it, just to know that it exists joyable: tks grizz: to finish out Zar, add then the length of your 2 longest suits grizz: and the difference in length between longest and shortest grizz: and if you have 26 points, you open joyable: uh grizz: so a quick Zar evaluation of the E hand here grizz: !s=4+1=5 grizz: !d=6+2=8 grizz: !c=4 grizz: 17 points so far grizz: now add the lengths of the 2 longest suits, !d and !s grizz: so 17+6+4=27 grizz: and the difference between the longest and shortest, !d and !h grizz: 27+6=33 gojoe: this is nuts...I am leaving grizz: ok grizz: 26 points is an opener in Zar points hoppyjack->Club: Why would the delta be 6. ? grizz: that is far beyond the scope of today grizz: oh, simple math grizz: 6-0=6 grizz: the difference between the longest and shortest suit hoppyjack: I missed it. Sorry about that. :-) grizz: so let's get back to LTC BILmanager: ~D let's keep it simple - this is for learners not matheticians grizz: nope, that is not my intent grizz: just wanted everybody to know there are alternate methods of hand evaluation ramseygf: is the zar count any better evaluation in Trumps or NT grizz: back to LTC grizz: E has 5 losers grizz: and W has 6 grizz: total of 11 grizz: looks like i goofed earlier, when i said E has 4 losers, it grizz: it's really 2!s, 1!d and 2!c=5 grizz: add the losers together and subtract from 24 (magic number, trust me) grizz: and that is how many tricks LTC predicts that you can take grizz: so 24-11=13 grizz: LTC predicts that EW can take 13 tricks, IF they have sufficient controls fiscryder: may I comment pls.... think most helpful would be learning to reevaluate hand during bidding...eg... have agreed suit with pard and have single in opps bid suit/ grizz: sure, LTC takes that into consideration grizz: for example, W has only 1 !D loser fiscryder: ty I think for begins/intermeds its a weak pt grizz: and 2!c losers grizz: let's do some more hands grizz: E has 8 losers grizz: 2!s, 3!h, 1!d and 2!c grizz: W has 2!s, 2!h, 2!d and 2!c grizz: 8+8=16 grizz: 24-16=8 grizz: so LTC predicts that EW can take 8 tricks in their best fit, which is !d grizz: looks like they lose 1!s grizz: 2!h grizz: and 2!c kbkoch: Would you open with 12 hcp and 8 losers in 1 and 2nd seat? ramseygf: would W not say to himself i have a loser less so 3D grizz: sure, and we'll get into that in just a bit grizz: so ops take 5 tricks, and it does in fact make 8 tricks in !d joyable: using rule of 20 would not open e grizz: right grizz: and here is another facet of LTC: an opening hand should have no more than 7 losers grizz: so E is not an opening hand per LTC, with 8 losers panim: but E is not red grizz: true joyable: grizz - sorry I arrived late what does that stand for? joyable: LTC grizz: nevertheless, W will have every right to expect that E has a full opener in 1st or 2nd position grizz: LTC = Losing Trick Count, for latecomers joyable: tks grizz: this is an alternate hand evaluation method grizz: so EW performs according to the prediction BILmanager: !D I published an article on LTC in last week's Gazette which those who are interested can print out grizz: excellent grizz: what does NS do? grizz: N first grizz: and here is the first adjustment to LTC grizz: the singleton K is a loser grizz: since it must be played on the first trick grizz: so N has 1 loser in !s grizz: !hJ9 for 2 more grizz: 3!d losers grizz: and 1!c grizz: 7 total grizz: and S has 3!s, 1!d and 3!c grizz: for 7 grizz: so LTC predicts that NS can take 24-7-7=10 tricks in their best fit, !cs grizz: if NS play in !cs, ops take: grizz: no !hs grizz: 1!d grizz: 1!c grizz: and 1!s grizz: 3 for the ops, 10 for NS grizz: so LTC is right on the money, both ways grizz: any questions on this hand, LTC-wise? joyable: n ydannac: n ramseygf: how do LTC work with weak 2's grizz: same grizz: we will probably see one shortly ramseygf: south might have 2S grizz: S losers are: grizz: 2!s grizz: 2!h grizz: 2!d grizz: and 2!c grizz: 8 losers, not an opening hand Jeschiwa: 2!c? Jeschiwa: I see 1!c grizz: !C32 are losers, but not the K grizz: S hand, not E Jeschiwa: y,ok grizz: N hand: grizz: 2!hs grizz: 2!ds grizz: and 2!cs joyable: how many losers to safely open hand grizz: how many !ss? grizz: 7 is safe to open panim: 2 hoppyjack: 2 ydannac: 2 joyable: ty grizz: right, another adjustment here grizz: just as the singleton K is one loser, grizz: unsupported Qx is counted as 2 grizz: so N has 8 losers grizz: not an opening hand either grizz: however grizz: after 2 passes, the restrictions on opening are relaxed somewhat joyable: how much is somewhat grizz: and with nice defensive values, N could safely open 1!c joyable: some players open any garbage grizz: yes, and i do not recommend opening trash even in 3rd seat BnBeever: I would open 3!c on the N hand if I knew p would open all 12 counts here grizz: might work, could backfire in a big way grizz: if N were not a passed hand, S could bid 2NT here to show 11-12 and no 4-card major grizz: but grizz: since N is a 3rd seat opener and might be light, grizz: some tact is required grizz: lol BnBeever: GIB forgot to bid? grizz: when was the last time anybody played 1!D???? grizz: heavy sigh grizz: back to LTC Dianne0516: Drinking again :) grizz: N has 8, S has 8 grizz: so LTC predicts that they take 8 tricks, making 2 grizz: ops take 2!s grizz: 1!h grizz: no !d grizz: and probably no !cs grizz: making 4 grizz: so LTC does not work accurately on this hand grizz: though it does predict a part score, and not game grizz: why not? grizz: one reason is that it works best on a 9-card fit grizz: and we have only 8 here grizz: a double 8-card fit in the minors grizz: another is that the !dK is in the slot grizz: and W is finessed right out of it grizz: another is that the !CQ falls on the second !c trick, and the J is finessible grizz: if S guesses right grizz: otherwise makes only 3 grizz: so LTC is not an exact science grizz: just another tool for you grizz: where LTC is really valuable is on shapely hands with good fits grizz: not on flat hands like this grizz: let's look at EW grizz: W has 3!s grizz: 2!h grizz: 1!d grizz: and 3!c TheMoak: how can !c J be finessed if you catch Q? grizz: 9 loseers grizz: right, always a !c loser grizz: back to LTC grizz: W has 9 grizz: E has 1!s grizz: 3!h grizz: 3!d grizz: and 2!c ramseygf: how many LT's can an overcall be credited with? grizz: could be as many as 9, usually no more than 8 grizz: so if EW play in !S, LTC predicts that they take 24-9-9 grizz: =6 tricks grizz: so let's see if that holds up grizz: EW would lose no!s grizz: 2!hs grizz: 2!d grizz: and 2!c grizz: making 7 tricks grizz: so LTC is off by 2 in the NS, and off by 1 EW grizz: as frequently happens on balanced hands grizz: one more hand to evaluate, and then i will talk about loser expectations grizz: W first, since he dealt grizz: 2!s grizz: 2!h grizz: 2!d grizz: and no !c grizz: 6 losers grizz: so W is an opening hand, and then some grizz: just as Milton point count shows grizz: E is 2!s grizz: 1!h grizz: 2!d grizz: and 1!C grizz: 6 losers, so it's an opening hand and then some as well grizz: in fact, 24-6-6=12 tricks grizz: so LTC predicts that EW can make small slam in their best fit grizz: IFF they have enough controls grizz: and sure enough, they have a 9 card !h fit ramseygf: make big slam grizz: actually makes 7 joyable: y grizz: with 4 pitches on !cs joyable: very nice hands grizz: notice something here, very important grizz: EW have only 29 hcp!!! grizz: but small slam is cold, with a play for 7 grizz: so this is a good example that LTC works well on distributional hands grizz: now i'm going to throw some numbers at you grizz: write them down if you want, or retrieve the chat log later grizz: a minimum opening hand is 7 losers grizz: a minimum responding hand is 9 grizz: an invitational opening hand is 8 grizz: oops, i goofed again grizz: an invitational response hand is 8 grizz: an invitational opening hand is 6 grizz: and a game forcing opening hand opposite a minimum response is 5 grizz: a game forcing response hand is 7 grizz: a 2!c opener is typically 3 or fewer grizz: is everybody still with me? grizz: anybody not? joyable: me grizz: opening hand is 7 ydannac: y grizz: invitational opener is 6 joyable: i'll write it down and then will be ok Wanda310: y grizz: GF rebid by opener is 5 grizz: minimum responder is 9 grizz: invitational responder is 8 grizz: GF responder is 7 grizz: all assuming, of course, that a fit is found grizz: so let's look at a few more hands grizz: i will try to find some that show invitational hands ramseygf: tks grizz: robots are fired joyable: lol grizz: N has 7 losers grizz: 2!s grizz: 2!h grizz: 3!d grizz: no !cs grizz: S has 7 also grizz: 2!s Dianne0516: The bots need to take some of your classes Pete grizz: rofl grizz: 2!h grizz: 1!d grizz: 2!c grizz: so S already knows that there should be game in this hand, if a fit is found grizz: even though S has only 10 hcp grizz: sidebar here grizz: if S had less than 10 hcp, it should bid 1!h grizz: but with 10 hcp S can take 2 bids, and it's fine to show the !ds first grizz: aha! grizz: a fit! joyable: I would have bid 1 spade in West's seat grizz: so LTC predicts that the hand makes 4!hs grizz: although it's only an 8 card fit grizz: still, playing imps, NS should bid the game ramseygf: and go 1 down grizz: yup, on this hand it doesn't make grizz: but it does if the !hQ is in W grizz: so it's a 50% game and they should bid it ramseygf: using points i would invite game by using 3!H is that wrong ramseygf: Partner might have 12 pts joyable: lose 1 diam 2 spades...?? heart not sure loser grizz: no, i would not criticize 3!h here grizz: the QT in E is guaranteed to win one trick grizz: but put that T in the N or S hand, and it makes easily grizz: and neither Milton nor LTC counts Ts TheMoak: how abiut E/W hands? grizz: W first grizz: 1!s grizz: 2!h grizz: 2!d grizz: 1!c grizz: 6 grizz: an opening hand grizz: except that with length in !d, and S bidding !d, W must be cautious grizz: because: grizz: that suggests that NS might not have a fit grizz: and if NS don't have a fit, then EW don't have one either grizz: and in a misfit situation, you would rather defend than declare joyable: k grizz: back to EW TheMoak: what is E's LTC? grizz: E has 2!s grizz: 2!h grizz: 3!c grizz: 7 losers grizz: so LTC predicts that EW can take 5 tricks in their best fit grizz: which is !s grizz: do they? ramseygf: 18-13=5 grizz: making 5S, not making 5 tricks :) ramseygf: so EW will probably win contract grizz: EW lose no !ss grizz: 2!hs grizz: 1!c grizz: so LTC is off by only 1 here ramseygf: an adjustment by W because he has D yes grizz: and joyable, who would have overcalled 1S in W, would be a big winner :) ramseygf: yes, 2 5card suits grizz: right, 5/5 hands are very powerful grizz: notice one other thing grizz: either there is a double fit, grizz: or a monster cross ruff grizz: the one other thing that we should notice here grizz: is that if W doesn't bid at first opportunity, the price of mistake goes way up grizz: so if you will permit me one digression here joyable: y grizz: let me mention the Barry Crane rules grizz: Barry was perhaps the best matchpoint player of all time grizz: and just a part-time bridge player, he had a big job in Hollywood and only played local tournaments grizz: his rules are: grizz: 1. get in fast grizz: 2. get out fast grizz: 3. the 3 level is dangerous grizz: when was the last time anybody got rich defending a doubled 1-bid? joyable: lol grizz: probably never grizz: because if defenders can defeat ops' 1, they surely have game or slam of their own grizz: ok, thx all, seeya next week grizz: for those who are leaving grizz: i will stick around for a few minutes to answer questions grizz: no questions? then it's nap time in grizz land annnew: what is nexct week's lesson? tx grizz: what? you expect me to plan that far ahead? lol grizz: i expect to do what i started off with, defending random hands grizz: demonstrating the principles of leads and signals that we have talked about grizz: ok, thx for attending, and i hope to see you all next week grizz: bye now
