If you want to do well at this game, you need to know how to defend reasonably well. Having a good system of signalling on defence will get you a long way towards that. This board was nearly always played in 4S by East. The bidding could have gone a number of ways but the defence should have gone only one way. Yet, out of nine declarers in 4S, four made five, three made four, and only two were down one, which is as it should be, given what should be a fairly routine defence.
