I pushed the turn too hard, I think if he had a seven he would have reraised the flop. I guess I was paranoid about getting sucked out on if he did have a hand like A7 or K7. As you can see, we were both deepstacked, so I wanted him to pay. But I think I pushed too hard, I definately think I could have won more. How would you have played this?
