However, I would not have bet 100 on the flop. You should have bet more or gone for a CR. Your hand is vulnerable to a lot of turn cards (as you have seen but any card under a 10 could have make a 2 pairs hand with an Ace).

A CR will likely kill the action but that's ok given your hand is strong but vulnerable. A flop bet of 150 or 200 will be called by few hands, A10+ (with or without 2 pairs) but should'nt be called by a drawing hand.

If you expose yourself to many hard decision in a tourney, you are going to make at least 1 costly mistake, by betting harder, you minimize the chance of having to do these decisions...
