Doubles of artificial bids often ask for that suit to be led, but sometimes a double helps the opponents. Here we look at Anti-Lead Directing Doubles, when they apply, and how they are an improvement.
Here we look at another tool for Advancer, called the Rosenkranz Redouble, that allows us to further refine the type of support we have for partner's overcall.
Another week, another double! This time we look at a cousin of the responsive double (used by Advancer) called the Snapdragon Double.
Here we look at how to use a double for a game try, called a Maximal Double, in competitive auction that has little space to communicate with partner.
A 1NT overcall by a passed hand is an illogical bid. Here we look at the meaning of this and other bids - specifically the Sandwich 1NT overcall.
When the opponent's opening bid "could be short," this can lead to some confusion in competitive bidding. We examine how adjusting our agreements helps us better deal with this situation.
When our side opens the bidding with 2C and the opponents interfere, we need good agreements on how to deal with this interference. Here we see how to approach these actions.
Here we look at competing over Strong Artificial Forcing bids (like 2C) with 2-suited hands using the Mathe convention.
This week we look at Responder's options when RHO enters our 1NT auction with 3-level interference.
