ok so my two peneth.... 3c muppet stayman transfers 3s=transfer to 3nt 3nt = 5/5 minors 4c = slam try in hearts, 4d = acceptance of slam 4h = sign off 4d = slam try in spades, 4h acceptance of slam, 4s sign off 4h = slam try in clubs 4nt = sign off, 4s = rkcb, 5c to play where you have 3 card support but think might be safer to play in 5 that in 4nt...if teams. 4s = slam try in diamonds, 4nt = sign off, 5c rkcb, 5d to play where you have 3 card support but think might besafer to play in 5 than in 4nt if teams. also just introduced 2nt - 3d - 3s which shows only 2 hearts and 5 spades...a bit like muppet...this caters for 3523 or 3532 shape from responder. with 55 in majors use muppet stayman then probably get response of 3h...then bid 4h to show 5/5 can also bid 5h to show slam interest or 6h to say pick a major. also can use 6 ace roman keycard blackwood...e.g 2nt-3nt(55 minors) 4nt or 4h as roman keycard if you want to keep the bidding down. if we are weak with 5-5 in the minors we will just settle on passing 2nt or bidding 2nt-3s-3nt.
