Opening lead by West is 7♥?!
Context is 6 team round robin with 5 board rounds, weak field, but this round is against the other decent team.
Should you play low from board on trick 1, or should you win the A and hope to develop your 9th trick in diamonds (several interesting lines in diamonds based on guessing the split and the position of the Q and/or T)?
