发帖数: 20570 | 1 If the declarer knows that east always play low with Kx or Kxx and west is
capable of playing T or 9 from T9x, he still should play low to Ace because
it is the percentage action. T9 is only one layout, T9x is two (for example
T93 vs. K2 or T92 vs K3, they are identical. This is another example for
restricted choices, since with K32, the guy can randomly play 2 or 3 here,
so the chance for this layout is half). |

发帖数: 2804 | 9 I think you have to hope that declarer only has 4 diamonds and no D10. Then
ducking DK will work out more often:
1) When declarer has D9, ducking gives declarer a guess. If you cover, then
technically correct play for the declarer is to finesse partner's D10.
2) Even when partner holds T9x (which means that you *should* cover DK),
ducking may still work out OK, since partner should falsecard with D9 or D10
on first round of trump. So declarer may still guess wrong, not all is lost

发帖数: 2804 | 10 西家如果盖Ｋ当然就没事了。不过T9x里出9或10，这是mandatory falsecard，E没出肯
定是不对，不应该是这个层次上的选手该犯的错误。至于出了之后庄家是否仍然击落DK
，这个就没法说了。 |

发帖数: 2804 | 11 Interesting analysis, but I think it is slightly flawed. The theory of
Restricted Choice assumes that the equal cards will be played out randomly,
this may be true when the cards involved are QJ, JT, etc., but majority of
players don't do it with 32. People just aren't aware that 3 and 2 are
important, many will just play 2 from K32, not 3. Also, being "capable" is
still different from "will". In the actual play, the East player is
certainly "capable" but slipped in this occasion. So on average ... 阅读全帖 |

发帖数: 1295 | 12 Actually, usually an expert player don't sort his cards, and all cards are
memorized. Every time he needs one, he just opens his hand and pick it up.
Since it's really random which card, 2 or 3, is found first, the
equiprobability assumption here is reasonable.

发帖数: 623 | 13 Now I've found the true distance between a real expert and me: I always
choose to sort my hand! -- to this topic, even when I sort my hand, I revoke
every once in a while.
To the original problem. If dummy has QJ9x, you would never cover. If dummy
has QJ8x or less, my opinion is you should cover. If you don't, and if oppo
has the 9, the half times oppo's guessed wrong is offset by the times you
hold KT tight, as now oppo know that they need to play the drop. Meanwhile,
if you don't cover and pd ... 阅读全帖 |

发帖数: 2804 | 14 Exactly. Ditching HQ creates a sure entry to dummy, which can be useful. It
doesn't really cost anything since dummy had HJ, unless west led from Axx,
which would be virtually impossible, and East's attitude card confirmed this.
However, if you keep drawing trumps, West will have the opportunity to
discarding HK!! If East started with T9x in hearts that will create an entry
for east. :-)
For the same reason, winning HJ to ruff 3rd D is actually dangerous, if West
indeed only had 2 diamonds. West... 阅读全帖 |

发帖数: 2804 | 15 Maybe declarer is holding Qx in hearts and two diamonds, heart continuation
is the only way to allow the contract to make. Or declarer may have 7-2-1-3
shape, playing a diamond to knock out DA entry is important, otherwise
declarer pitches a club on HJ. When East holds something like 3-3-5-2 shape,
this can be the worry.
If East has KQJxx in diamonds and T9x in hearts, many would discourage to
get partner to switch to diamond. It is not always correct, but it's
somewhat normal. |

发帖数: 155 | 16 After a 2-month hiatus from poker, I went to Turning Stone again last week.
There is a major poker tournament going on so there are more players than
usual.
Bought in for the maximum $ 200 in $1/2 no limit. The table was not too bad.
There were two boys and a black guy who seem weak. After a few orbits, I
limped in with T9o in late position, and the flop was T9x rainbow, giving me
top two pairs. I bet the pot, about $15 and one of the boys called. The turn
was an 8. The pot was about $45. The vi... 阅读全帖 |
