I land in a 5♦ contract because I mistakenly expect North to have 3-card ♦ support. 3NT is probably a better contract; anyhow, it's all about the play.
Trick 1: ♥J-Q-A-6
Trick 2: ♥8-♣6-♠7?!-♥10
When West discards at trick 2, I realise that 3NT was absolutely cold without needing any finesses because of the singleton ♥J. So the job is to make 11 tricks in 5♦.
How should I proceed? FYI, ♦ split West 4 - 2 East
