Our Tuesday Challenge Night expert on 19 September, Will Jenner-O'Shea, spoke to about 40 of us on "How to detect your partner's aggression".
He was talking about bidding style - and coping with partners that might range from "cautious" to "adventurous". With the more aggressive partners he suggested not always leading partner's suit - she may only have the jack. He also suggested some self-assessment of one's own aggressive tendencies might be useful.
If you missed this talk you can at least check Will's handout - and assess your own tendency to be adventurous.
