Final Pot: $113

My thoughts when I made this bet were:
1) I want to build a pot
2) I was thinking AK or AJ as very likely hands who would probably pay me off all the way. (Equally I didn't want to see a Ten or King hit the river too much =])

However, thinking after the hand I'm thinking 30-35 would've been a much better bet and I'm not just being results orientated. The point here is that if he does indeed have AK or AJ here he's likely to raise a 30-35 bet thinking maybe I have AT or KK or something similar, equally the villain doesn't have many outs.

A friend of mine was saying 40 looks good but I don't like that bet because 90% of the time in my opinion someone who calls 40 here calls 50.

Anyway just trying to analyse my play a little more.


EDIT- No PT or PA on this computer and didn't have any strong reads on villain - he hasn't been out of line though. Limped more than I agree with though.
