Here are the answers to the subsidiary questions in my Christmas Competition.

3. Look only at the East hand. After opening one diamond, what should he rebid when West responds (a)

one heart; (b) one spade; (c) one no-trump; (d) two clubs; (e) two no-trump, balanced, no four-card major, game-invitational; (f) three spades, a splinter bid showing good diamond support, at least game-going values and a singleton or void in spades.

The answers are: (a) one spade; (b) two spades (although three spades isn't wrong); (c) pass (although two clubs could work out well); (d) three clubs; (e) pass; (f) three no-trump (warning partner of good spades).
