A splinter is a double-jump in a new suit that says three things at once: I have strong support for your suit, I have game-forcing values, and I have a singleton or void in the suit I just bid.

That's a lot of information in one bid — and it's exactly what partner needs to evaluate slam.

In this workout, Coach Ace covers how to recognize a splinter hand, how partner evaluates the fit (wasted values vs. useful values opposite your short suit), and how to continue the auction after a splinter. Ten hands put you on both sides of the table — making splinters and responding to them — and you'll come away with one of the most powerful tools in your slam-bidding arsenal.
