I play a very simple big club system with control responses. Please help me with a system after bidding goes 1C 2H(weak).

dbl-takeout shape, 6+ (you might have this promise a rebid over a 2S rebid)

2S-natural, GF

2N-natural, GF

3m-natural, GF

3H-stayman (i.e. 4 spades, balanced hand)

.....3S-no stopper

.....3N-stopper, no fit

.....4S-fit

3S-asking for NT stopper

3N-11-13 balanced with stopper
