Bid seven spades.
This is one of our favorite scenarios. No matter how many hearts your right-hand opponent overcalls, you bid the same number of spades! Over two hearts, you would bid two spades; over three hearts, you would bid three spades; etc. Wouldn't it be funny if the hand were as shown?
Yes, East had a two-heart bid but accidentally pulled the seven-heart bidding-box card and placed it on the bidding tray without looking.
Now, in all seriousness, should you sacrifice, trusting East to have his bid? Not even the world's best bidder - whoever he is - could answer this one. Psychology, knowing your opponent, and the state of your bridge match may help you in determining an answer. Our guess, however, is that it is more often right to bid. Unfortunately, the scores do not reflect this. Hope East's little slip didn't ruin your final score.
Double = 10
Pass = 5
Seven spades = 0
