Do you felt top set (when it's the nuts on the flop)?

[wire]

I lost a few all-ins tonight.

Twice I had top set on the flop, potted or reraised the flop, but got callers. What do you do if a draw card hits (flush or straight) and you're set all-in?

You have 10 outs to boat up or make quads.

When are you pot-committed, what percentage of your stack has to be in the pot already?

What if it's a 3-way all-in, that changes the implied odds, right?

Get as much of your stack in the pot on the flop, is that the optimal play?
