DVD 6-Doubling and defence against doubled contracts
Doubling and defence against doubled contracts

The Presenter defines doubling for penalties as “I expect the contract to go down and I want to maximise our score”. He states that club players do not double enough, and should be doubling about 5 times a session (one of which will make the other four getting very good scores). Helpfully he includes a section on when not to double.

Very clear and a useful insight into getting a better match point score
