Its ok taking a stab at it after he checks to you. He could easily be on QQ, KK etc after that preflop. If he plays back at you you have to fold and give him credit for the A though.

The play on the flop was OK, if you are reraised you fold.

It is the preflop part of the hand the I think was misplayed.

what do you put your opponents on ?

Felippe I can put on TT-AA, AK, AQ, so I can justify the call, but what do you put Squaz on ?
I would have to put him on AA-QQ on I think you should have folded preflop
