You find yourself in a four-board playoff to win a little KO. The first three boards seemed pretty flat, so it might all hinge on the last hand. You pick up the following hand:
Spade GraphicK J 6 Heart GraphicK 9 6 5 Diamond GraphicJ 8 4 3 Club GraphicJ 7.

With neither vulnerable, partner opens 1Heart Graphic and RHO overcalls 1Spade Graphic. You make a sound raise to 2Heart Graphic. LHO raises to 2Spade Graphic. Partner introduces a new suit with 3Club Graphic.

The auction now diverged at the two tables. What do you do in the following cases:

1) RHO bids 3Spade Graphic?

2) RHO bids 4Spade Graphic?

The match and the event are on the line …..

UPDATE: You had better double 4Spade Graphic if you get the chance. At the other table they failed to do so and partner bid 5Heart Graphic, got doubled and went for 300, guessing hearts correctly. Your partner played 4Heart Graphic undoubled and guessed them wrong for -100, but winning 5 IMP’s.

Partner’s bidding was a bit imaginative, with lead direction in mind. You needed to do your part to win the match.
