Two Way Checkback Stayman
After openers rebid of 1NT, both 2 and 2 are used as versions of Stayman.
a) 1 1
1NT 2 (invite only)
2 : 4 diamond, not 3 hearts
2 : 3 hearts, minimum 1NT
** 2 : 4 spades, minimum 1NT
2NT : Clubs, not 3 hearts, minimum 1NT
3 : 5 clubs, 2 hearts accept invite
3 : 4 diamonds, 2 hearts accept
3 : 3 hearts, accept invite
** 3 : 4 spades, 2 hearts, accept
3NT : accept, 3-3-3-4
** Weak NT players frequently bypass spades to rebid 1NT. This sequence would not normally be possible after a 12-14 1NT rebid as opener would prefer to bid the spades to the NT.
b) 1 1
1NT 2 (game forcing checkback)
The auction is now forced to game. Opener bids in a similar manner to the above, but jumps to the 3 level are not necessary, and partnership may discuss their significance as regards distribution and HCP's.
