This is a puzzle for improving players - experts please let them have a shot first [unless you can see I've messed up the problem :)]

I rate myself as an Advanced player, so really should have got this hand right yesterday at the club.



Maybe 3H was an overbid, but ah well. West leads out two top clubs then switches to the 10. How do you maximise your chances of making the contract? If you play the Q, West will win the A and return a spade.

They say one way to get better in the play is to bid to bad contracts, so that's half there. :)

I did think this looked interesting, but no tries yet in more than a day. I'm not sure I see the trick, but here's my line:

play low heart to the A, now the diamond Q. If west wins and plays a spade I'll play low. If east wins
...then you're down, having lost a diamond, a spade and two clubs.
It's an interesting problem but I can't for the life of me see how to avoid a spade loser.

I think you're misunderstanding the plan. My reading was:
- lose two clubs
- win the switch in hand
- lead the Q
- when LHO wins, play small on the spade and win cheaply in hand, then cross to a high trump, play K and ruff a , hoping the J drops in 3 rounds so we've set up 3 cards for discards, or that LHO's spade holding included the J but not the K.

- if RHO wins the Q and returns a spade, win the A, then continue as before.

Sorry, as CamHenry read that obviously means low from the board and won cheaply in hand. It is a contingency if RHO leads from the J that gives extra chances. I think the lead from the J is more likely than from the K, and moreover, winning the Q later leads to more good stuff than just a trick, so that's my plan.
