Andrew’s favourite conventions (two)

The second in my series of Top Ten Conventions is The Weak Two opener. Almost universally played outside Britain, an opening bid of 2 , 2  or 2 ♠ shows a six-card suit and 5-10 points. It is primarily an obstructive bid and essentially the Weak Two does not bid again unless his partner replies 2 NT. This special response shows 15 or more points and asks the Weak Two to show whether he has a minimum (by rebidding his suit at the lowest level) or a maximum (by making any other – descriptive – bid).

North increased the disruptive effect of South’s Weak Two by raising to game. East-West had no idea whether he was bidding to make or to spoil and neither bid. Can you see what they would have been able to make? East-West could have made 12 tricks - a Small Slam - with either s or ♠s as trumps!
West led  6 – second top from a bad suit – to 4 ♠. Declarer won dummy’s  A and ran ♠ J to West’s ♠ A. West switched to ♣ 3 – he could not know that East’s  10 was singleton – and East won ♣ A. In a desperate effort to put his partner back on lead for as second play, East switched to  8. West beat  10 with  K, and worked out why East had risked underleading  A. He switched to  2 and East gratefully trumped with ♠ 9. One down – but hardly a victory with 6  or 6 ♣ making.
