I play agressive when I get hands at these tables, usually pot size bets most of the time. However, I don't get to the river often with a big hand such as this, so I usually don't have this situation come up much, when it does, I almost never betr the pot. I'll bet just like this, maybe 25, but do any of you think its best to pot it again?
