No Double Dipping!
I was North.
I Splintered to show point count. Obviously, I wanted to play in hearts. Should I just have bid game since three of my points were most likely going to be lost?
N DEALS
NONE VUL
I think a few things happened to derail this hand.
- You forgot that you should not Splinter with a singleton Ace or
- Your hand with a singleton King only counts to a16-point hand or so.
NO DOUBLE DIPPING! Remember, you can’t count points for the singleton and count points for the King; count one or the other. To Splinter as a rebid by Opener, game-forcing values should be around 17+ with consideration of your shortness. This hand is not strong enough to Splinter. - I believe that your partner forgot that 3♠ was a Splinter. Otherwise, she would not have bid 4♠, she should have simply bid 4♥.
So, the auction should have been:
N S
1D 1H
3S 4S
5H
