My partner opened one spade in first seat (favorable vulnerability). My right hand opponent passed. I wondered how to respond with this hand:
I thought splinter (response of 4 hearts showing shortness) is out because of my singleton king of hearts.
The hand is not good enough for a game forcing raise of spades by responding 2NT (Jacoby). I did not want to encouage partner to investigate slam.
And the hand looks to good for a limit raise of 3 spades. I don’t want partner to pass the invitation.
My solution: respond 4 spades. I want to make sure we get to game opposite partner’s opening. I think Bergen would agree with treating my singleton for its shortness feature rather than its high card points.
How would you respond?
