Been playing for 45 years, with an 18-year gap. Like Negative Free Bids. Wonder how effective a negative double of 1H ?denying ?four spades is. Like Kaplan Interchange. and strong jump shifts the way Edgar wrote them up forty years ago. Wrote the "Read My Lips" article in The Bridge World. Every word of it is true, except for the ground glass. Also a classical pianist, but don't play much any more. Do have an MFA in composition from the New England Conservatory.
Plus... it's free!
