At the table, I played a spade to the Q first, later discarded heart on diamond and then cashed AK and ruffed a heart.

I ran the hand by a few friends on the Irish team that made the B-final, telling them my line and we chatted about potential improvements. I think the best line is:

- Draw trump
- Cash Heart A and K (assume both follow small)
- Discard Heart on Diamond and ruff a Heart
- Fall back on the Spade to the Q if nothing else works

This line fails if the K is offside and RHO has exactly QTxx or LHO has QTxx(+)

Put another way, the line succeeds if s are 3-3, any honour is doubleton or singleton, RHO has 5+ hearts or LHO has the spade K.

Unless I'm mistaken, the only layout it fails where another line can succeed is with exactly QTxx on your right (and the K also on your right).

By my calculation this line is around 87.6%

3-3 hearts 35.5%

4-2 with doubleton queen or jack 9/15 of 48.4% = 29.1%

5-1 onside 1/2 of 14.5% = 7.3%

5-1 offside stiff queen or ten 2/6 of 7.3% = 2.4%

6-0 onside 0.7%

A total of 75.0%

stiff K 1% of rest = .25%

Spade onside 1/2 of the rest 12.4%

Giving a total of 87.6%

Our opponents had an auction that started 2-3; 3-4; 4NT-5; ??

2 was any GF, 3 showed primary hearts, 4NT was key-card for hearts, 5 showed 1 of 5.

Now the strong hand had a problem - he wanted to play 6, but how to stop partner being tempted to correct to 6 (or possibly view 6 as a grand-slam try with solid hearts and K or Kx in clubs)?

This was accomplished easily enough by pulling the STOP card out of the bidding box, placing it firmly on the table with something of a flourish, and then bidding 6. Partner duly passed without pause for thought.

The TD saw nothing awry - no adjustment, no procedural penalty.

Did the TD get a golden handshake?

If the T drops, why don't you just run the J and pitch a . Later pitch the other on the 9.

Very good idea.

That was what I did when someone dropped the 10 prematurely.

According to suitplay, the chances of playing the hearts for 1 loser are 84.7%, if it failes, having played AK and small to the J, if whoever wins it has the spade king that is also enough, so about 15.3*(9/20). (9/20 is the chance of spade K being in a hand already marked with 4 hearts). which by my count makes AK and small toteh J!h around 6.9%+84.7% = 91.6%
