My friend and I disagreed on how to play the hand. One player felt pushing and taking down the 1K while probably ahead and destroying the positional advantage of the limper was the best play, the other felt raising it and playing it on the flop was the best play.

The first player thought he could get low PPs to fold and maybe get calls from AQ or AJs, the second player felt like risking a stack for 1G was a bad idea.

After arguing awhile, I finally posted the hand here. Id really like to hear what everyone has to say on this one.
