sfi Posted December 2, 2011 Report Share Posted December 2, 2011 1♦ is the key system bid: 10-15, four+ diamonds, not balanced. It will be five+ unless .holding 4-4-4-1 or a five-card club suit. 1♥: 10-15, five+ hearts, not balanced. May be 4=4=1=4 exactly (rare). One of my regular partners and I have been doing something like this for years, and it works fine. The theoretical negatives from having the 4-4-1-4 hands in the 1♥ bid just don't cause problems in practice - we always treat 1♥ as 5 (and actually forget that it may not be most of the time). The real problem auction is 1♥ - 2♦ (which is FG). Sick as it may seem, we rebid 2♥ here and have yet to run into problems. Our 1♦ is actually either natural or 15-17 balanced, which also tends to reduce the threat of preemption, but having it just natural will ease the continuations.

Glad to see someone else not put off by opening 1♥ on four on a hand that happen 0.75% of the time.:rolleyes: Quote Link to comment Share on other sites More sharing options...
mikestar13 Posted December 11, 2011 Author Report Share Posted December 11, 2011 Another possibility for those who don't mind an ambiguous 1♦: 1♦ shows either minor but not both, with or without a 4-card major. 2♣ shows a minor two-suiter and 2♦ is free for whatever you need/want. After the 1♦ opener, responder looks for a major suit fit if possible. If no major fit is found, opener will bid his minor. A minor-suit response is pass or correct.

mikestar13 Posted December 16, 2011 Author Report Share Posted December 16, 2011 Been playing Real Diamond Precision in some Mid-Chart games lately--Kaplan Inversion over 1♥ is much superior to 2♦=F******y. ACBL regs really suck. Relay responses to one bids are Mid-Chart if game forcing and Superchart otherwise! Quote Link to comment Share on other sites More sharing options...
