When to bail out of NT

[pbleighton]

Partner opens 1NT (15-17). You have spades, but don't have enough for Stayman. Which of these hands bailing into spades:

6241:

1) xxxxxx-Ax-Qxxx-x

2) Qxxxxx-xx-Axxx-x

5341:

3) xxxxx-Axx-Qxxx-x

4) xxxxx-xxx-Qxxx-x

5) Qxxxx-xxx-xxxx-x

6) Axxxx-xxx-Qxxx-x

7) AQxxx-xxx-xxxx-x

6232:

8) xxxxxx-Ax-Qxx-xx

9) xxxxxx-xx-Qxx-xx

10) Qxxxxx-xx-xxx-xx

11) Axxxxx-xx-xx-xx

5332:

12) AQxxx-xxx-xxx-xx

13) Axxxx-Qxx-xxx-xx

The quality of the x's has an influence on whether NT or S is better but assuming tiddlers and a transfer "bail-out"...

 

Most of them,  ;D.

 

The exceptions would be 3, 4 & 5 (is 5 missing an Ace?). Many of them I would not regard as a "bail-out", several of them are candidates for 1NT-2H-3S-4S if P "super-accepts".
