The mechanics are straightforward once a hand has been classified into Lim,LimX,Min,MinX,Int,IntX,Str+. Initial classification is based on an hcp range defined versus an unbalanced/balanced hand.
The T&P Jacoby 2♠/2NT (T&P = Tried & Played although mostly many simulated hands, but it has worked well in actual play)
After 1♥-2♠ bid increments are based on strength
2NT +1 Min
3♣ +2 MinX
3♦ +3 Int
3♥ +4 IntX
3♠-4♦ 5+ Str+ ITL Q Bids
Following the first step responder may be able to place the contract or move to slam investigation after hand revaluation. If not responder shows shows his strength based on MLT/TP. For example when opener is Min.
After 1♥-2♠--2NT
3♣ 7.5MLT or lower MLT/TP equivalent
3♦ 8MLT or lower MLT/12TP
3♥ >8 MLT/10-11TP
This time opener may be able to place the contract depending on revalued strength.
After 1♥-2♠--2NT-3♣
3♦ 8MLT (i.e. a balanced minimum)
3♥ 6.5.MLT/15-16TP 2+KCs/1KC & Q trumps
3♠-4♦ 6 or lower MLT/17+TP 2+KCs/1KC & Q trumps
4♥ anything else.
After 3♥/an Italian Q bid responder can place the contract or continue slam investigation.
I'm still simulating the optimal revalued TP ranges to combine with the MLT so the above are initial indications
The advantage of this approach is that the contract can often be placed in 3/4M with little clue being given as to what to lead. I tend not to use the approach when I have an alternative 5+ card suit and a 3 card trump suit without honours and enough for a 2/1 bid.
Comments/questions welcomed.
