Rebid Problem/Possible Solution--Updated

You hold:
AKQJ9
ATxxx
K
xx

You open 1 Spade, partner responds 1NT and you bid?

Well, I bid 2 Hearts as well and we did miss a cold game this time. Partner had: x xx AQJTx J9xxx. One of the biggest problems I've had with standard bidding is this exact situation--opener's simple rebid in a new suit has a very wide range. One possible solution is the Gazzilli convention. Stacy Jacobs has a nice write up on her blog here:http://stacyjacobs.com/system-notes/major-suit-openings/. Basically a 2 Club rebid on this auction could be arificial, encompassing your jumpshift hands but also the problem-range hands. It starts around a good 16 points and responder's 2 Diamonds is a relay, game-forcing if opener has 16+. Our auction on the given hand would go-1S-1NT-2C*-2D**-3H***-3NT
*-Gazzilli--either semi-natural or 16+
**-8+ points any (gameforcing opposite 16+)
***-16+, 5-5 majors
