Hero ?
I think the real question is what would make this a call? My pocket pair of 8s is not good enough. Maybe jacks or queens. Then again being out of position perhaps I should just fold after the flop. I just was not sure if maybe he was was just trying to push me off the hand because of the positional advantage. He has to have either an ace or pocket pair better than 8. Purely mathematically I am probably a slight favorite. But the betting pattern says he is betting real value and I should toss it.
