Why no PF raise? MIxinG iT uP?!

That flop c/r is really gross, I hate bluffing with TPGK.

Against an unkown, there are two lines I would consider:

Bet/Fold flop. Bet/Fold turn if called. Check/Call river. (all assuming no hearts hit, check/fold if they do).

Check/Call Flop. Bet/Fold turn. Check/Call river.

I lean toward the latter, because then we get continuation bet monies in, and make him less likely to semi-bluff the turn.
