In an IMP-pairs tournament, you reach 7 (vulnerable) on south's hand, after a bidding sequence best forgotten (but where south's distribution was concealed, but had shown a club and heart control after opening one spade). What is the best line of play after a trump lead of the 6? (east follows with the 8)

Without looking too much into detail, it looks like a complete cross-ruff is in order. Win in dummy, cash the A throwing a diamond, ruff a heart, cash the A throwing a club, AK, club ruff, heart ruff, diamond ruff, claim on a high x-ruff.

 

Assuming I haven't missed anything, I need West to have at least 3 hearts, East at least 3 diamonds and clubs to be 4-3 or west having 5. Any of the above in addition to either opponent not having a trump to ruff with if they are out too early.

 

edit: gnasher's line below is better %age wise when trumps 2-1, only needs 1 suit to behave reasonably.

Win in North, ruff a heart, cross to A, ruff a second heart, ruff a diamond, ruff a third heart high, ruff a second diamond, ruff a fourth heart high, ruff a third diamond high, draw the last trump. With trumps 2-1, that works unless a red-suit is 8-1.

 

With trumps 3-0, I think we'll need to cash the top cards and crossruff instead.
