After a major suit fit has been found if there is slam interest by opener (15+ points):
1. Make the next higher bid, asking partner to give responses similar to Kokish help suit game tries. Responder bids the cheapest feature (Ace, King, singleton, or voids).
2. Bid 3 of your major to ask for trump quality. Responder bids cheapest non-trump ace with 2 of 3 trump honors; or 3NT with no non-trump aces with 2 of 3 trump honors; or 4 of trump suit without 2 of 3 trump honors.
With a minimum hand (12-14 points), bid the cheapest non-trump ace at the 3 leavel; or bid 4 of trump suit with no non-trump aces.
