All vul at teams. Strong-ish opps. After upgrading your hand into a strong NT, you find yourself in 3NT on the friendly looking ♣K lead. You can click next to see the play up until the critical decision. Now do you cross in spades and take the heart finesse or do you play hearts from the top preserving the ace of spades?
edit: opps play suit preference discards and standard count if it matters (and if you choose to believe them).
