My partner and I play Benji weak 2's in the majors. He has another partner who plays weak 2's in Diamonds Hearts and Spades and has asked if we can play this too. It means giving up the Strong 2 Diamond bid. In our current system 2 Clubs shows 23-24 points balanced or 8/9 playing tricks M/m, and 2 Diamonds shows 25+ points balanced or 9/10 playing tricks M/m, and Rule of 25 etc. for both.
We will now have only one strong bid other than 2NT - i.e 2 Clubs. I assume this will still show 23-24 points balanced, but what do you recommend regarding required playing tricks with an unbalanced hand?
Also, under what circumstances do you suggest responder can stop short of game. At present we say 2 Clubs is usually game forcing with 2-3 points and 2 Diamonds is usually game forcing unless responder has a bust. For example, if the bidding goes 2C-2D-3m, what sort of hand would responder have to justify a pass, (I assume 2C-2D is still just a relay and 2C-2D-2M-2NT is the negative response with 0-7 points. )
