You have this hand in 4th seat (favorable vulnerability). Left hand opponent opens with a weak two hearts, partner passes, and right hand opponent bids four hearts.
It’s your turn. What do you decide to do?
First thing to think about is what kind of hands opponents have. The oppening bid is straightforward, usually promising six hearts, 5 to 10 high card points, and likely loss of no more than three tricks vulnerable..
Right hand opponent usually has two kinds of hands for continuing the preempt. It could be somewhat weakish hand with four card support for hearts. Or, it could be a good hand with only two or three card support for hearts. You are somewhat in the dark, and that’s why preempts are so annoying. Those rascals have forced you to make your first decision at the four-level!
What can you deduce from your partner’s decision to pass in second seat? If responder had the weakish hand with good trump support, then partner would be short in hearts with a good hand. But partner did not double or overcall! Therefore, right hand opponent must have a big hand. You may not want to risk jumping into the auction if that’s the case. Unless, of course, you think you can hold your loss to minus 500 (down 4 in four spades doubled).Do you think your spade textue is good enough to hold your loss to down 4? Whan I saw this played on BBO, 4th seat chose to bid four spades. He went down four for minus 800 and a bad match point result. The usual result was minus 620 or minus 650 when opponents were allowed to play four hearts — above average match point score for the defenders..
