Toss it or felt it?..(600nl)

[snakekilla88]

This hand was from a few weeks ago, but I am reviewing some PT hands and taking a break so I dont get sick of poker, [img]/images/graemlins/laugh.gif[/img].

Villan here and me have been playing HU on a few other tables for awhile. I have seen him make a few bad plays, but hes not horrible. When playing HU he often will call OOP and cr most flops... and give up on most turns. I have kind of stopped 3betting him because he seems to never go away, and hasnt folded to any of my 3bets so I have been patient for the last 20 minutes or so... I have not seen him overbet before.
