A player opened 1NT (12-14) and partner responded 2 Clubs (stayman) Opener then bids 2NT and when questioned said it shows 2 four card majors!!
I cannot find this convention in any of my Bridge books nor EBU training manuals or on-line. Can anyone advise the validity of this bid as it has flaws in my opinion. If responder has say 5 hearts and 4 spades but very few points and wants to do a weakness takeout by bidding 2 Clubs - if opener makes the above re-bid of 2NT then partner would have to go to the 3 level in a weakness takeout in hearts.
