When you're this deep you're going to want to practice pot control with a medium-strength hand on this flop. OESD is good, but flush draw definitely diminishes it. Call the flop, call the turn, rake in the dough if the board pairs on the river. Otherwise, call down any non-heart river (unless you were unlucky enough to run into set over set, but doesn't seem likely given this betting). The pot will be much more reasonable so his river bet will be easier to call with just a set on this scary board.
