[threeonefour]

DueceKicker,

easy threebet the river and call the 4. EDIT: folding to the 4 would be madness even if you were capable of such a fold.

lets review:

you call preflop from a blind (you have [censored] as far as everyone else is concerned)
you bet call the flop (i guess you have a pair)
you check raise the turn (top pairish)
you bet the river (still top pairish)
now you are raised.

you really haven't represented a monster (not exclusively at least), as such his river raise doesn't represent a monster. easiest three bet in the world, if its capped (QT being his mostly likely hand) i would expect to be good more than half the time.
