Hold on.

The key to this play is knowledge of your opponent. If he had been going all in or agressively stealing blinds your call may be proper. I've seen some crazies push hard with less than top pair, and have regularly succeeded with their agression.

In most cases, once you have the A-5 and the turn comes, you have to make a decision given what you know about the player. A-K likely? Would he go all in with that? How has his play been?

I know the results, but I'm fairly weak tight and unless I felt really confident, I walk when he pushes all in. He has you covered, after all. Those 2 pair generally aren't going to be enough at this stage in a tournament.

My real question is, if you hated pushing the call button, there's probably a reason you hated it. So why did you talk yourself out of the fold? The answer to that question will determine much more whether you botched this one.
