How to score?

1. At duplicate bridge there are several ways to score +550. The common ways are to bid and make three notrump or five of a minor (doubled, nonvulnerable). How else can +550 be obtained?

2. On the last board of a Swiss team match, the contract at one table was four spades doubled, which was made exactly, vulnerable. The same contract was reached at the other table, but it was not doubled. Amazingly, the board was a push! How can this be?

3. At duplicate bridge there are two ways to obtain the rare score of +270. One is to bid one notrump and win all 13 tricks. What is the other way?

At the other table four spades was reached by the opposite side after a bidding mishap. This was set eight tricks (vulnerable) for 800, which is a push compared with 790 for making four spades doubled. (The IMP scale nullifies the 10-point difference.)

2nt+5

(2*30)+5(30)+10+50=270.

1nt+6

30+6(30)+10+50 = 270
