You meant small H to K, then small H to J? In case (i), small H to K wins, then small H to J wins, now what?
【 在 vikingpirate (pp++2.9) 的大作中提到: 】 Ruff in hand. Then small D to K. (i) If it wins, two round of C and small D to J. (ii) If it fails, try H 33. D finesse could be the last chance.
I like your play, but I don't think you can say 'done' yet. What if RHO is the one who has 4H? He can exit with H when you play a D to him, and you can still lose 2D if unlucky?
【 在 vikingpirate (pp++2.9) 的大作中提到: 】 Yes, should be H. Then throw HQ on SA, done.
Why would RHO duck HA? Technically possible but in practice not, even for world class.

Not keeping SA also has some benefit, I think. Suppose RHO has HATxx and D control, he will be thrown in immediately at first round of H. In this case, keeping SA and trying H3-3 will go down I believe.
【 在 imlate (toolate) 的大作中提到: 】 That is the benefit to keep SA!
Yes. And also need to manage entry properly. For example if you ruff spade at trick 1, you cannot draw trumps immediately, you have to play a heart toward dummy, if it wins then you draw 2 trumps ending in hand then another heart. That risks heart 5-1 and someone gets a ruff, but the risk is worth taking. Also, if trumps are 3-0, you probably need to draw all of them before playing the second heart, LHO can hop HA and force you to guess by playing a diamond, but c'est la vie.
【 在 vikingpirate (pp++2.9) 的大作中提到: 】 It is a very interesting hand. It is more likely a BridgeMaster problem rather than real hands. A perfect hand for ACBL bulletin dealer problem. It includes some elements of "Morton's fork", avoidance, and a throw-in endplay. Not easy to figure out all the possibilities at the table.
In that case, it is always down if RHO ducks the first heart (we are not going to finesse with H9). Also, he may have the second trump to exit.

you play two rounds of trump if not keeping SA. and I learned that RHO won't duck HA in practice:)
【 在 imlate (toolate) 的大作中提到: 】 In that case, it is always down if RHO ducks the first heart (we are not going to finesse with H9). Also, he may have the second trump to exit.
Why is RHO thrown immediately? Say RHO returns a heart, do you finesse with 9 or play Q?

If you keep SA 1) you make the contract whenever LHO has HA 2) when RHO has HA, you make the contract when H are 3-3 or RHO has A8xx or A10
The only time when playing SA at trick 1 gain, is when RHO has ATxx, AND you decide to play H9 on second heart. Note that you will lose when RHO has A8xx. You cannot cater for either ATxx or A8xx.
【 在 josephine (jo) 的大作中提到: 】 OK, one needs to guess. If RHO has ATxx or A8xx, though, not keeping SA still has better chance?

第一个是关于红心的打法。这种Qxx对着KJxx的结构，要争取拿三墩，标准打法就是对
着KJxx出两次，可以兼顾左手Ax的情况。对于这副牌来说，这样打还有一个重要理由，就是对方没法迫使你做过早的选择。比方说你出红心到K，然后红心拉回到Q，除了损失左手Ax的机会之外，左手现在第二轮HA赢了以后马上出方块，可以迫使你在不知道红心是否3-3的情况下要马上决定是否飞方块。一个好的做庄路线，是要尽量去尝试所有的
可能性，而不是被先期剥夺选择。
与上面所说相关的，第一墩不要出SA，是一种观望战略，也是保留选择的重要法宝。类似的牌例很多，但这副牌里的作用比较subtle，是为了产生一个可能的对右手方的剥光投入。
说到剥光投入，就要看一下方块结构。AQT或是AQ9，是最适合投入的结构。两轮红心之后，如果左手不上A，你就用SA垫去HQ，将吃一张红心。如果红心3-3， 自然不用飞方
块。如果左手红心原先为Axxx，则右手方已经没有红心，你打方块，如果左手出小你就放D9，左手出10或J你就放Q，右手吃进之后就被投入了，只能给你一吃一垫或是让你做好一张方块。
所以这个打法，基本上可以在左手有HA的情况下确保定约完成。在右手有HA的时候，仍然可以先试红心，不成的话再飞方块。
