20-board graded duplicate session. The topic will be doubles (part 1). It covers the following: when to use a take-out double, responding to partner’s doubles, when to overcall instead of doubling, re-opening doubles, doubling with stronger hands. A hand record will be provided after play, along with a brief review of 2–3 of the most challenging boards. This is a green point event and a voucher is required to participate.
