It would be nice to make it with ♥Kx and ♠AQ offside, by extracting all of LHO's clubs then endplaying him with a heart. However, I can't see a way to do that.
Suppose I duck the club, win the next one, ruff a diamond, ruff a club, cash ♥A, and lead another diamond. If LHO has four clubs, he can ruff in and exit with his last club, giving me a ruff and discard but not giving me another trick. If LHO has only three clubs, that makes him 6223, so he can ruff in and give his partner a spade ruff.
At the moment my best plan is to take a spade finesse.
Edit: I can do it if LHO is 4234: duck the club, win the next one, ♦A, diamond ruff, club ruff, ♥A, diamond ruff, club ruff, diamond ruff, club ruff, exit with a heart.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn
