loner stop textbook play

[LeftyK]

I'm in S1 defending the loner. Notice how my p and then myself let the other one know that they have a suit covered. Against a flush trump hand this is moot, but loners are stopped on 1st or last tricks mostly. This is how you stop a successful loner attempt.

This isn't just for loners, either. Anytime you throw off an Ace on a trick, you're telling your partner to lead that suit because you've got it covered.

If you would have thrown off the king, then you'd be telling your partner that you don't have that suit covered. This would have confused them and they could very easy end up keeping the wrong suit until the end.
