Scoring: XIMP
Expert game on BBO. You are South and the auction is as follows:
1♥ 2♦ 4♥ p
p dble p 4♠
all pass
Before you ask, I may just as well tell that this NS pair can't have a 5-card major when opening 1NT. Anyway, you lead ♥K and partner follows with the deuce. You have this agreement:
1) Low card is encouraging.
2) High even card is suit preference for the lower side suit.
3) High odd card is suit preference for the higher side suit.
So North has no help in diamonds or clubs; not ♦A, not a singleton diamond and not a singleton club either. Basically, your partner asks you to continue hearts unless you have an obvious switch.
Do you? What do you lead at trick 2?
