if EP is the preflop raiser....then i would lean toward just calling. his most likely hands are AK, QQ, JJ, or maybe some kind of
![The Nine of Diamonds [9d]](https://www.pofex.com/images/smilies/9d.gif)
[8d] type hand. or maybe AQ if he's a looser raiser. you're freerolling against AK and the diamonds, and you have his underpairs drawing to two outs, and AQ drawing almost dead. why drive him out?
additionally...if he's got AA or KK...it is also to your benefit to see a card and hopefully hit a diamond.
