I think I've been mixed up with Karosel 2D(18~19 balanced) as Mexican 2D(19~21 balanced)... #contractbridge

Summary of my version of the convention & its defense. Forgot to mention how to deal with those interferences, but: -Responder's NT(6+pts, long suit) asks for their stop so opener relays to Cs to pass or correct -X=usually T/O -XX=3+pts -Over (2M): 2NT=Lebensohl(3+pts), X=5+, FG #contractbridge

Apparently you could have simple responses to transfer majors at the 3-lv (as Dalmas' original ver.) - or have detailed sequences so you transfer to spades at the 2-lv. (2S Rodwell size ask could be used with the former) Also, this made me look up '2NT-3S forces 3NT' & related stuff like that...
