Have I polarised myself too much on the river Vs this reg? To top set of J9s and J9s I don't have too many combo's of.
Therefore should I have gone just under half pot because then i rep a lot more value combo's like AQ.AA,KK sets and J9, given that I have an aggresive image? Or has this guy just just made a terrible call and I played it fine?
