发帖数: 6500 | 12 3NT其实是个很愚昧的定约
赛门塔K吃进后开始进功方块
草花A还没顶出来，就算能飞中赛门塔的红心Q，只要是KQx的红心，也只有8墩牌，所以
只能打KQ双张或者杜波恩Qx忍让了

发帖数: 2804 | 15 所以他没必要事后喋喋不休了，立即转攻方块是一个隐晦的错误，庄家只能选择砸HQ。
正确的防守是回黑桃，给庄家飞红心的选择。

发帖数: 20570 | 16 That's another story. Still, without running simulations, he should clearly
know that DT is a stronger lead. The failure of leading DT is probably due
to some other facts. For example, he feels that his partner is more likely
to hold long spades or opps have a good game and only aggressive leads are
more effective. That doesn't mean that he doesn't know DT is the natural
lead of this hand. IMO, players at his levels all know that DT is a popular
lead.

发帖数: 6500 | 17 我觉得杜波恩这副牌是犯了错误的
庄家打红心小的时候，基本可以看见庄家的牌有
黑心Ａ 草花Q 红心A
庄没有开1nt 方块上最多一个A
应该Q吃进开始进攻方块

发帖数: 642 | 18 That will be my choice too. But before I tried to say that, LZ already gave
the actual lead. I did not expect DT lead will hit the jackpot (although it
does), but it is a safe lead. At this bidding sequence, a safe lead is my
consideration.

发帖数: 2804 | 19 同意。从单套打法来说，红心放小没有大错，庄家经常不能猜对。但是这个牌没有必要
，因为庄家在明手只有一个快速进张（SK），即便后来飞死同伴的HK，红心仍然堵塞，
庄家一下子拿不到9墩。
牌桌上如果要从Qx中放小，必须不动声色，可能一下子想不了这么多。
这副牌其实两个人防守都有些问题。杜波恩的责任更大些。

发帖数: 2804 | 20 Seriously, it is a toss-up. D10 lead is safe, but passive, you may lose a
tempo. Spade lead may cost, but if partner has as little as SJ, it can be
effective. In this hand, partner has KQ in diamonds but nothing in spades.
It doesn't have to be that way. The real question is whether you should
defend passively. The bidding suggests passive defense, but your club
holding is a little worrisome. If declarer has source of tricks (such as 5
clubs), you need to start attacking, then the most promising suit is spades.
All in all, passive lead is ok, but I will feel more confident if my club
holding is something like KJxx.

发帖数: 2804 | 21 再说句题外话，南家这副牌似乎叫错了。同伴2NT之后，应该叫3H而不是3NT。手里三张
A，适合打花色定约，如果同伴有5张红心的话，打4H更好。 |

发帖数: 272 | 22 能有机会和 杜/赛 面对面交手, 还是很让人羡慕的.
2NT 应该是没有想寻求H 的打算了, 所以应该不会5张.
南家的牌虽然A 多, 控制不错, 但是 3334, 怎么看也觉得更象 3NT.
要说担心, 也许是担心pd 的 S 和 D 是Qx 那种, 如果那样的话, 3NT 让pd 打就更好
了. 但是已经没办法了. |

发帖数: 2804 | 23 啊，对。这个进程我看错了。应该是北家使用check-back，而不是2NT。红心套虽然不
强，但是梅花有配合，旁门两个双张，如果同时红心配合的话还是打花色定约好。当然
，如果叫2NT是为了寻求一个swing，也是完全可以的。但是本手是check-back。

发帖数: 20570 | 25 JT9xx is a nice suit facing some sort of support. facing Axx, you have good
chance to lose only one trick. Facing Kxx, your chance of losing one trick
is still significant. Facing Qxx, you need to lose AK to set it up and NT is
generally dangerous because of your weak D holding. Facing xxx, you may
want to just play 2H instead of 2nt because you don't have source of tricks.
5-4-2-2 is a suit oriented shape, especially when your partner opened your
4 card suit.
2NT is so bad in many way. If partner has no extra, he would pass it and you
will win less tricks in NT than in 2H. So 2H is a much safer contract than
2NT. If partner has extra, you may miss excellent 4H and play 3NT. Even pass
or 2H or 2C sign off is better.
bridge is a very simple game if you play it in a simple way and keep the
simple but important principles in your mind.

发帖数: 524 | 27 这时飞中也有9墩牌，但是没桥兑现。
黑桃J赢进第一墩后，如果动红心，对方必然转攻方块。
所以只能希望草花先滑到一个，然后再取4墩红心。
由于手顺的关系，只好打左手双张大牌。
尽管是手发牌，还是这样地有学问。这副牌肯定是我发的咯。
