15/30, silly TT spot

[augie_]

full game. opponent is very tight. he's also fairly agressive. i have TT in the hijack and i open. villian cold calls OTB

the flop is K [img]/images/graemlins/club.gif[/img]4 [img]/images/graemlins/heart.gif[/img]3 [img]/images/graemlins/diamond.gif[/img]

i bet, and the opponent raises. i think for a second and call (mistake?) my plan is to call down.

the turn is the 5[img]/images/graemlins/heart.gif[/img]

i check, and in a shocking move, the opponent checks.

the river is a 6[img]/images/graemlins/spade.gif[/img]

should i check or bet?
