2200

This is lack of method, and GIB(and lots of human would too)takes a poor gamble. Switch spade K to club K and 6C is almost laydown. For human, there are gadgets showing "minors+spades shortness,slam interest"(after 3NT, N would simply bid 4S to show it), and South knows wastage thus stop at 4NT, but for bots, there is no such thing.

♠7654 ♥J843 ♦Q652 ♠A ♠AQJ8 ♥A ♦A1073 ♣KJ72 Vul 4S at both table. Clubs are 4-4, spades 4-1 but finesse on, so just another 10 trick dull board? No so at GIB's table. A heart was lead, club to the Ace, diamond Ace back, club K, club ruff, 1st spade finesse held, another club ruff, heart ruff back. You already have 8 tricks, and with AQ sitting behind K, just throw a diamond and wait for two more trumps, since the 1st finesse held. No! GIB cashed spade Ace!!! Ah oh, 4-1 break, 13 imps. This GIB outsmarted its LHO since playing LHO for ducking with spade Kx? Once again, compare to my previous "all time greatest" posts, this is nothing.

Good point. GIB indeed leads internal sequence, such as 9 from K98x. Still, I was disappointed that GIB did not apply avoidance play in clubs(N is not the dangerous defender). Of course, the requirement probably is too high for GIB。

I know 2S is a bad bid but GIB is very vulnerable handling disturbing, but it won't matter at all, since EW are too rich. I'm glad I found a good lead, H9, but still， it won't matter at all. All declarer has to do is to set up clubs first, and it will be another boring dull board. No! GIB cashed spade ACE then try clubs. Suddenly I have an entry and my lead paid off. H8 went through hearts again and GIB went down in one of the coldest dullest 3NT。 From machine's point of view, I still don't get it. What's the purpose of cashing spade Ace first? Of course, compare to my previous "all time greatest" posts, this is nothing.

Seriously，as a bidding problem, suppose South does not have the ♣K, is there another way to check ♥Q, or AJxx in diamonds?

At my table, ruffed at trick 1, declarer played ♠K and Ace, finding trumps 4-1, down 1. At GIB's table, ruffed at trick 1, ♠K，♠9，covered by S!!! 17 imp swing. I still don't understand, what makes bot cover?

Holding the most spectacular trump support of all time, and NINE tricks single handed, GIB decided partner probably had trouble counting, thus it's better idea to stay out of trouble.

Even in early 90's，the bridge playing bot product(many of them peek because otherwise they are simply not playable toy) would not produce this kind of result.

[hv=pc=n&s=s872hjdt8762c6542&w=skqj94h83dcakqt97&n=s65hqt9652da4cj83&e=sat3hak74dkqj953c&d=w&v=e&b=16&a=1c2h3d4hppp]399|300[/hv] GIB sitting EW. 4H by South probably not a too smart human move, but was there a netquake so the GIB server crashed at the time?

After an everyday auction, 1NT-(2S)-3S(stopperless lebensohl stayman)-pass-3NT-all pass, GIB led 4th best from KQJ9x. I had 8 quick tricks. Dummy came down with 10x of spades,with Axx in hand. 9 now.

Today GIB held Q10x A10xx Axx AKx and opened 1NT， after 1NT-(2S cappelletti) -3NT(slow shows fast denies by me)-pass GIB decided 4H might be a good idea. It wasn't.

My apology if it has been asked before. Is it possible to add "instant replay” in the robot match？Whether it's personal challenge against robots, or, in the robot tourney(the replay result certainly doesn't count, but just to give you a chance to see how things would go differently）?

标准的含义： 1D-1H过来后，西“扣叫”2H，根本不是什么“顶底”，就是自然叫，6张红心好套，坐1H后面。 至于对方叫到3NT加倍，请问妳想过没有，即使同伴猜到妳是梅花套，他梅花缺门咋办？他倒是想攻，攻不出来咋办？ 这种牌，完全用不着想什么乱七八糟的，就正常的，自然叫。但是描述过程中，以梅花为主，如果有时机，可以顺出一嘴黑桃。 1.同伴并没有争叫1S；2.妳并不想拿这样的梅花，去打个4-3的2S

Bobby Wolff，由于他深信过去使用奇偶（罗马）信号的意大利队在使用该信号时作弊（原因见2楼），因此他主政期间，致力于禁止奇偶信号，所以北美短期禁止过奇偶一段时间，或许这是听说的由来。 但......后来又开禁了。 普通信号含义是单一的，即使出现节奏上的停顿，也不至于使同伴获得非法信息，且不存在守方较庄家的信息优势。

Teams, all white. Pd opend 1C， RHO jumpd 2S， and you held ♠KQ ♥xx ♦QJ9xx ♣Axxx At my table, my pd tried 2NT(which I strongly disagree)， raised to 3. Not a success. Dummy put down ♠xxx ♥AQ10x ♦Kx ♣QJ9x Quickly concede down 3, after a normal spade lead.Stopping at 2NT is irrelevant. The difference is extra -50. At the other table, our opp didn't get any better. After 2S， 3D was bid(my preference, which is obviously an overbid but no other alternative). They quickly bid no play 5C. Seems a hand with no solution.

据我所知，不禁，但一流职业牌手几乎不用，而且会告诫付费客户不要用。 这是因为，这种信号很容易陷入“不义”，妳有那张信号牌还好说，没有，慢吞吞地思考半天出一张，那同伴立刻知道妳有什么了，这跟作弊就是五十与百步，而且是很低级的作弊。

下次请大写。 同伴的8，固然是欢迎，但同时也否认了109，当然他完全可能是J8xx中欢迎，此时黑桃已通了。 从庄家打法看，很像红心持AK，这样从点力看，同伴应该有DA加叫的2S。 红心当然不能再垫，再垫红心就通了。 所以，我会垫S，既然同伴标明有DA，就算黑桃长度赢墩减了一个，你3墩S,方块AK已经够下了，何况同伴完全可能还有DJ。 反正只要你打同伴持DA，无论如何都会下，即使黑桃不通，还有同伴持方块AJ，穿方块的机会。

ABC问题。 问A后“停”5阶将牌，标准含义是0则停住，3则上。所以东根本不存在有什么要多想的，如果为了不丢可能的7，当然是顺路一下6H，强调赢墩来源质量。 但是常理度，西几乎不可能一个也没有就独自问A，所以，根本不存在“6是否成”的问题，而是有没有7的问题。

第一副，开1D，全pass掉危险太大，开叫2C，准备2NT，如果有低花贯，什么低花Stayman之类的不会叫不出的。 如果，开了1D，根据第二副流程，那就只有2H了，跟黑桃配合没关系，就是一个综合性逼局叫品，总要在这里先建立逼局形势，具体是什么下轮澄清。 不可能2H承诺黑桃配合，否则你很多逼局牌没法叫了。除了现在这样靠码点的双套，还有单套D，只想check止张怎么办？

这就根本没什么好想的，完全没有选择。 今天号称专家级的牌手，没有一个不开的。

1S不保证一定4张，也可能是没有合适的再叫，只好先从3张叫起，试图尽量压低。 2S保证4张，且是比较好的低限开叫，好的13、4点的样子。 道理是，如果没有那个插叫，正常过来，那也肯定是1D-1S-2S，换句话说就是那边12点低限开叫，没有插叫，也是得至少到2S的，所以这里一样，2S不是额外extra。但考虑到有插叫，那么至少“好一点的低限开叫”总该有的。

I was South, and I highly doubt if I would be as confident when playing with human. [hv=pc=n&s=sakj4ha84da985ca2&w=sq6hjt9762dq32ct6&n=st8753hk53dck8753&e=s92hqdkjt764cqj94&d=n&v=n&b=5&a=p2ddp2sp3sp4dp4hp5cp5dp5hp6cp6dp7sppp]399|300[/hv]

刚跟人喝一杯的时候，知道了一点这副牌的内情。 首先，请相信不需要这个那个的发明，东西的体系约定，是一定会叫得出7D的，尤其是Moss是个洞察力非常强的牌手，定将后透视到同伴牌情，最终改将，他是很精于此道的。 实际情形是，作为东的Grue忘了约定，以为4H是splinter（根本不是re-transfer，这么占空间的愚蠢约定Moss是决计不会用的），其实东西有一套完整的装置体现单缺，4H显示的是方块单缺，那西当然止步了（而不是“重新接受转换”）。那么当东5NT表示7的兴趣，承诺所有AK齐全是，西当然认为方块都好了，于是就去了。 如果东没有忘记约定，东西是肯定可以叫出7D的。

Does anybody ever mention that, the real advantage of Flannery, is when you are NOT using them? If you do NOT open Flannery, you don't have that kind of hand. Because systematically, playing Flannery means 1H-1S promise 5, so there is other superiority for further bidding structure developement. For example, ♠AKx ♥A109xxx ♦Axx ♣x You open 1H and pd bids 1S. I am sure you will see various votes from expert panel. There will be vote for 2H, 2S， 3H, 3S, and......a fancy 2D. Playing Flannery, you have no problem at all. Pd promises 5, so it's a clear cut 3S.

One possibility: GIB can see sure 400, but can't be sure if doubled 6H runs to 7C, would be more than 400.
