to the above two posters,

hero has position on the villain (he is the bb) on this hand.

i don't like the 3-bet smurf. if he is weak-tight what hands is he checkraising you with against which you're ahead? does a weak-tighty make this play JK, K of spades? that's the only hand he might do this with of which you're ahead.

what's his hand range here? set, flush, JK w/ K of spades, maybe JA? against that a 3-bet is bad.

i just call here and just call the river unless a spade falls.
