It is probably results orientated, but I thought his aggression was slightly high and thought he wasn't legitimate.

Buttons FF was 40 so I thought there was a good chance I could take it down there. In hindsight the pot is small and I have medium pair with a weak kicker. The board is also unco-ordinated so I am only winning vs a bluff. But as I said I thought this guys aggression / looseness warranted the play.

I am looking to improve so I can understand this and it helps my play. How big of an mistake would this be. Is it big / small?
