Mike, does your 2N and 2M rebids for opener all show extra's?
fwiw, this hand was bid with a new partner. I opened 1D and ended up playing in 5
♦.
No: the scheme is as follows:
2M shows 4-5 or better and a good 14+ hcp (or compensating values as in good suits and 4-6 or better)
2N shows stoppers in the majors and a weak notrump hand (or 18-19, intending to raise 3N to 4N). The stopper requirement is not absolute: xxxx would suffice
3
♣ shows 4+ clubs, and is silent about values
3
♦ is a very good suit and slight extras
3M is a splinter in support of clubs (thus 3
♣ implies no shortness, altho the splinter will be a stiff, not a void)
2
♦ is a default call: merely denies the ablity to make any other call. Thus could be a 4 card suit and doesn't deny a major.
My feeling is that 2/1 fares especially badly on hands where both partners have some extras but not enough to unilaterally drive beyond 3N. So any scheme that allows opener to show a 4 card major, over 2
♣, on minimums and 14-16 counts seems to me to be problematic. That is why I like the 'reverse' to show basically at least a King above an awful opening hand. This allows responder a little more leeway with his 15-16 count....he needn't worry about reaching 4N with a combined 27 count and no big trick source.
The cost is accuracy whenever opener has a single suited diamond hand and there isn't room to adequately explore (mainly) choice of games (and occasionally slams). My experience so far leads me to think that this cost is worth paying, but I'm always on the lookout for a better approach....I truly do feel that this is a very weak area in bidding theory in a strong NT realm. Weak notrumpers have different issues.
