Some comments on the auction:
Opening the South hand is aggressive but would be the choice of many experienced players. The 2♠ cuebid shows a good hand, typically with support for opener’s suit. At favorable vulnerability, West decided to sacrifice in 6♠ after North’s leap to slam. Notice North’s pass over 6♠:
This action is forcing because after North–South freely bid a vulnerable slam, the opponents cannot logically be allowed to declare undoubled. The pass asks South to double with one or more spades, but to consider bidding on with first-round control (the ace or a void). South bid the grand, and West doubled.
How would you play 7♥ on the lead of the ♠A?
