To close out the hand history and respond to some comments.

I pushed and the 3 villains folded. Not as big of a pot as i'd have liked, but decent. I was hoping that someone would come along for the ride with something like TPTK or a gut shot.

Interesting observation by limpin, the CO (who made the initial flop raise) was playing A 10 suited. He thought about his fold the longest. I have no idea what the other two played.

As for the initial limp, it's not my usual play either. I had been dealt pocket 10's three times in the last 15 or so hands, so i just varied the play a little. I was having some problem getting action on my raises with a tight table image. I limped, would have called a raise for set value, and folded to any overcards and aggression.

I considered the reraise option, knowing that if a flush hit and the board paired I probably would have stacked at least one...maybe two of the others in the pot.
