grizz: Hi everybody, thanks for attending another in a series of lessons on Defense. grizz: Chat logs and hand records are stored in your computer for later review. For information on how to retrieve them, go the BIL homepage or email me at Grizz@GrizzBridge.com. grizz: I teach private individual, pair, and small group lessons. If you would like to know more please email me at Grizz@GrizzBridge.com. grizz: Archives of previous sessions are available at GrizzBridge.com, on the Lessons and Archives page located at: http://www.grizzbridge.com/Lessons_and_Archives.php grizz: There are almost 50 sessions logged there now, lots of good information. grizz: There will be lots of questions. I want to address them all, but in a manner helpful to all, so please ask them in open chat. grizz: If I forget a question while answering another, please remind me. grizz: I encourage participation by all kibitzers grizz: So jump right in with a comment, question, or bid at any time, but please do so in open chat. grizz: There are only 5 basic types of defensive strategy at the beginning of a hand. grizz: These concepts are out of the book "How The Experts Win At Bridge" by Burt Hall and Lynn Rose-Hall, the Bridge Book of the Year in 1997. grizz: By way of review, and for those who are new here, the 5 lines of defense are: grizz: 1. Force declarer to ruff, and lose control of his own trump suit. grizz: 2. Active defense. grizz: 3. Passive defense, let the lead come to you. grizz: 4. Reduce ruffs. grizz: 5. Create trump tricks. grizz: Again, if you need review on the 5 Lines of Defense check out http://www.grizzbridge.com/Lessons_and_Archives.php and scroll down the page until you find those lessons under the BIL listings. grizz: Briefly, here are the lead guidelines for each of these different strategies. grizz: 1. Forcing defense - lead your side's strongest suit. grizz: 2. Active defense - also, lead your side's strongest suit. grizz: 3. Passive defense - top of a sequence, or a worthless suit grizz: 4. Reduce ruffs - lead a trump grizz: 5. Creating trump tricks - lead from your own or toward partner's shortness grizz: So choosing a lead depends on what your defensive game plan is, referring back to the 5 Lines of Defense. grizz: When you know WHAT you intend to accomplish, it is easier to decide HOW to get it done. grizz: This week we are going to continue looking at example hands and auctions, consider defensive plans and choose leads. grizz: These example hands are not predealt, they are random. grizz: So I have not analyzed them, rather we are all looking at them for the first time. grizz: The bidding will be done by the bots, though I must sit in one of the seats during play to control the pace. grizz: I have no idea who the declarer will be or which seat will be on lead, so you may kibitz all 4 hands. grizz: We will put our heads together and come up with a defensive strategy based on the auction, the hand on lead, and the 5 Lines of Defense. grizz: let's move on to a hand we defend grizz: a question about balancing grizz: S has the right shape to balance here, with 4!s and shortness in !h grizz: but not anywhere nearly enough hcp grizz: Mike Lawrence says that in an auction like this, assume that pard has an average 7 hcp and go from there grizz: E has passed, but that does not mean he is broke! grizz: ok, when ops have preempted that is a prime case for Active Defense grizz: try to find your side suit winners before they go away grizz: and when you have AK in a side suit, there must be a powerful reason to lead anything else grizz: no defense beats this one cdt: how did Gib know to switch to club? grizz: good question, i thought the 8 would encourage the bot to continue the suit grizz: maybe the bot didn't want to set up the Q for a discard dae: no other logical lead? dae: looking at dummy grizz: and if that is the logic at Trick 2, a !c is the only logical switch wyoming33: do you think the bots read your signals? grizz: they ought to grizz: there is a file somewhere on BBO that tells you how the bots bid and defend, but i don't know where that is offhand nome: do u think they know the hands grizz: hard to say, they do seem to play better than they bid grizz: to find out what a bot bid means, click on it nome: I think Fred has them impowered to see other hands grizz: could be, i have no inside information on that wyoming33: i doubt that JohnnyHiLo: i believe the gib software does have an option for the program to peek grizz: could be dae: it's under Help at a table Gibs wyoming33: LOL then no one would play in the Gib money tournies grizz: ok, the bot has violated a basic principle of leads grizz: when ops have bid NT behind your bid or overcall, does that mean that pard should not lead your suit? dae: why ? 4th from ln=ongest suit? grizz: 4th from longest suit makes sense if there is any entry to cash tricks later grizz: the only entry in N is in !cs, and that's a longshot wyoming33: I would think twice before leading it with NT bid behind it bwd1: North has no entries so no reason not to lead !H grizz: right grizz: the only time when it makes sense to lead something else is when leader has a GOOD suit of his own, AND outside entry(s) so he can cash the long tricks grizz: so !cs is not a good suit grizz: and there are no entries grizz: so lead the suit of the hand that does have the entries boom1925: Maybe the bot thought w has double stopper for hearts and he only has 2 hearts so is hoping pt has clubs? grizz: makes an overtrick on the !c lead grizz: lets see what happens on a !h lead grizz: y, there is that possibility grizz: but frequently the NT bidder will only have a single stop grizz: or even just a psychic stop! grizz: slightly different bidding sequence, with a different dealer, but this is an important point grizz: first time around, the bot lead 4th best !c from the N hand grizz: and i wanted you all to see what happens if N leads a !h instead grizz: aha! grizz: now we have the timing on the hand grizz: btw, the lead of this card has an embedded signal grizz: in case N ever gets in grizz: S had 3 left, the 852 grizz: and the card that i lead here to clear the suit shows where my entry is grizz: big card, big suit = Spades grizz: little card, little suit = Clubs grizz: middle card, middle suit = Diamonds, on this hand grizz: makes no difference here, since N will never be on lead grizz: but it is a good habit to develop grizz: since you never know when it might be a critical piece of information for pard to have wyoming33: yes PedroG: y grizz: aha! robzim: go out and come back in -- that helps sometimes grizz: no overtrick that time grizz: and there is another little trick to see on this hand too - i will resend the hand, and if bbo blows up again please follow me to another new table grizz: so far, all the same grizz: but this time N is a little cagier about discards grizz: seeing a possible endplay coming, he saves a small one grizz: lol the bot followed a different line of play this time grizz: and you can see that the !h lead here made a 3 trick difference in the result JohnnyHiLo: right. the bot computes different scenarios each time by dealing out several possible deals and will play a different line. grizz: what i wanted to show you was how N can avoid the !c endplay by saving a small one at the end grizz: which is a great trick to keep in mind on hands like this grizz: a kib asks "why did E bid 3!H? I always am puzzled by cue bids" grizz: that is Western Cue, a method of dealing with op overcall suit and asking whether pard has a stopper for NT grizz: on this hand, NS bid !hs grizz: and EW had bid !d and !s grizz: the 3!h bid says that E has GF values, and interest in NT, but concern about !hs grizz: so if W has a !h stopper, then W should bid NT grizz: so Western Cue is an Asking Bid, not a telling bid grizz: but be very careful when using this bid, especially if you have not played with pard before robzim: but with a singleton Club, is that enough to want to be in NT? grizz: Western Cue is old stuff for those of us who live on the left coast, but this bid has a cousin - grizz: !c is not as much of a concern as the ops overcall suit grizz: Eastern Cue is the cousin of Western Cue grizz: Western Cue asks, but Eastern Cue tells grizz: so it is important that you and pard be on the same page when making that cuebid! cdt: Do you have to show that on cc or alert? grizz: cuebids are considered self-alerting grizz: and it would be a good idea to put it on the cc, just in case grizz: on bbo, we sometimes don't know where pard is from grizz: overall i think more players use Western than Eastern, but it should not be assumed Dianne0516: Why not just bid nt (not Eastern)? grizz: E or W? Dianne0516: If you are playing Eastern grizz: W can't do that unilaterally nome: is it true that E-cuebid is after three suits bid and Western after two suit has been bid? grizz: without knowing whether pard has values for game Dianne0516: doesn't apply here, just wondered why not bid nt instead of Eastern if playingit grizz: E bid NT? is that the question? grizz: dangerous without a !h stop dae: or C stop grizz: y, that too Dianne0516: No--you said some ptnrships bid Eastern--so with these ptnrships--why don't they bid nt instead of Eastern Cue wyoming33: she is saying since you are telling why not just bid 3NT grizz: ah PedroG: maybe Stop in one but not all grizz: i don't play Eastern cue, so am not an authority JohnnyHiLo: she is saying the 3nt is saying that she doesnt have a stop grizz: ok, and what does W do then if W doesn't have one either? grizz: scramble for a fit at the 4 level? cdt: yes I think so grizz: and that is the danger of the Eastern cue maysie: alternatively - could E bid 3C's? grizz: somebody asked earlier about east vs west after 2 or 3 suits are bid grizz: i don't think there is any widespread agreement about that, though of course a pair could have that agreement nome: I did ty grizz: alternatively - could E bid 3C's? grizz: also dangerous grizz: since it could be a natural suit bid, looking for safe haven with no !h stop grizz: so !c is not an asking bid playing WQ if ops have not bid that suit grizz: when ops overcall, that is the dangerous suit in NT grizz: so that is the one you need info about when considering a NT game ydannac: ty grizz: ok, any other questions on this one? grizz: it should be clear that the !h lead is superior grizz: even though N has that 7-card !c suit, there are no entries grizz: and establishing a long suit only produces tricks when there are entries that let you cash the slow tricks grizz: so the rule is - grizz: when pard overcalls and ops play NT, grizz: which is almost never! JohnnyHiLo: ok. sorry. grizz: if pard has a good enough suit and enough points to overcall, and ops have enough stuff to bid 3NT, grizz: the odds of the 4th hand having both a good suit and outside entries is very low grizz: not impossible, but very rare grizz: and would only happen when ops were gambling with a long suit and outside controls grizz: ok, let's move on grizz: S is a very nice hand for Unusual 2NT grizz: so N must decide here grizz: is 4!h likely to make? ydannac: y grizz: if so, can 5!c be held to only down 2 doubled? ydannac: 6 grizz: y, we can see that, but N has to guess grizz: so N must figure that W has a hand like what you see here grizz: too good for a preempt, but not good enough for a 2!c opener grizz: so what does S need for an Unusual 2NT? grizz: not much besides shape sascha3: 4 losers not good enough for 2C? grizz: depends a little on agreement sascha3: ok grizz: most use 2!c with a 9 winner hand grizz: some will with 8.5 sascha3: yes grizz: so how to calculate winners with the W hand? anegada: 4 grizz: one way is to count losers, per Losing Trick Count, and subtract from 13 grizz: W is a 4-loser hand sascha3: 9 grizz: y, darn close Wanda21: y sascha3: lol hard to judge tho grizz: if the !HQ were the K, that would be worth a 2!c opener sascha3: yes ok:) grizz: ok, so N knows what kind of hand W has grizz: back to what S needs for Unu 2NT grizz: should be at least 5-5 in the minors grizz: so max 3 cards in the majors grizz: so max 3 losers in !h and !s, from N's POV grizz: monster !c fit grizz: and stiff !d, so great cross ruff possibilities grizz: with the !CKJ, there rate to be no trump losers grizz: so if N is counting tricks, he comes up with max 3 major losers and 1!d grizz: down 2! PedroG: 6!h grizz: y, but darn hard to find it after the Unu 2NT PedroG: :) grizz: and clearly this is the best way to play trumps - if W is long in !hs, he is probably short in !c grizz: interesting hand maysie: W could start cuebidding? 1H P 1S 2nt 2C?...... grizz: it does make 6!h EW PedroG->Club: !d lsoing only grizz: y grizz: but the Unu 2NT bid really threw sand in the gears ydannac: finese the !D Q and make 7 grizz: and this hand really shows the power of shape grizz: y grizz: with only 12 hcp, and worthless !s and !h values, NS take 10 tricks! grizz: only 8 working points! cdt: If west oprnrf 2Clubs could unusual 2 NT get in ? grizz: yes TapTap->Club: e shd bid 5h grizz: then the auction would have gone 2!c-P-2!S-2NT cdt: ok thanks grizz: and same from there on out grizz: so it is clear to us looking at all 4 hands that E should compete, not X cdt: yes PedroG: and W may have bid 5!h grizz: but would it be so clear if you were looking at only the E cards? PedroG: he know that he doesn't lose !c and probably only 1!d cdt: no wyoming33: without any !C prob west shd bid 5!H over the X ->cdt: and maybe 2!s too TapTap: 5 and 5 in c and e has 3 so p cannopt have any grizz: E can't know for sure grizz: and W can't either, with 2 losing !ss grizz: so we have a game of high stakes poker, and nobody knows for sure! PedroG: :) grizz: if S does not jump in with 2NT, EW probably find the slam grizz: let's just see, shall we? PedroG: y grizz: and if bbo blows up again, we will call this session over and i'll see you all next week :) grizz: tada! grizz: lol PedroG: chiken GIB's grizz: they miss a cold slam grizz: but then again, 680 sure beats 200! dee_dee_20: bid 3!h as W grizz: i can't, the bots are bidding dee_dee_20: oh wyoming33: and that is passable grizz: but i can fire them :) Dianne0516: drinking oil with alcohol again Wanda21: tks bye !h :) PedroG: ty for a great Lesson Pete :) Dianne0516: lol PedroG: hehe wyoming33: west is showing 20 pts - maybe east should do something with those 13 pts - dont know what though grizz: lol we can't get there :) grizz: so maybe E must find a forcing bid, or just jump to 4NT Dianne0516: lol grizz: now we get to see whether the bots play Voidwood wyoming33: dangerous grizz: seems they don't grizz: if they play Voidwood, then 5NT shows 2 controls and a useful void grizz: if not, who knows? jaymac: which they have......... grizz: y, W has exactly that hand, but the bid explanation shows something different grizz: well gang, time is up wyoming33: explanations sometimes make no sense grizz: Do we have any final questions? PedroG: :) ty Pete Dianne0516: Thanks Grizz :) jaymac: Many thanks ydannac: Thanks Grizz, see you later!H!H dotfl: tks LadyStar17: Thanks, Grizz!!!!! super great lesson!H!H grizz: y, and sometimes the explanation is correct, but the bot makes the wrong bid anyway ladygolf: ty Pete :) cdt: Great pete thans :) JohnnyHiLo: thanks. grizz: That concludes today's lesson, and next week we will have more quiz hands on opening leads. grizz: If anybody needs help retrieving the hand records or chat log, please email me at Grizz@GrizzBridge.com. grizz: Thanks for your interest and participation, and I hope to see you next week. grizz: Thanks also to Maureen, Rosemary, Fred and the wonderful people at BBO who make this all possible. PedroG: Lisa told me Jana will replace her grizz: Thanks all for coming, i'll see you in a week anegada: still interested in small group ->anegada: ok, please drop me an email :) PedroG: ty :) grizz: Bye now anegada: ok ->PedroG: y, and it turns out that Jana and I have a connection - wyoming33->Club: need 2 for a few boards practice PedroG (Lobby): ? ->PedroG: she used to teach Linguistics at the University of Oregon, where i received a degree in Russian in 1971 PedroG (Lobby): hehe it's a small world ->PedroG: :) ->PedroG: seeya a little later
