50NL FTP: top set on monotone board

[overun]

Effective stacks of 90. Villain and I had been playing pretty aggressively against each other. One hand earlier in the session, I raised in LP w/ A4 or some crap, villain and another player called. Flop comes out 5J3, first guy checks, I bet, villain called, other guy folds. Turn comes a 9, I check, villain bets, I raised BIG, villain folds and said he had KK.

Overall, villain has been playing pretty tight, but ever since that hand, he's been in almost every pot with me. Nothing major happens 'till this hand...

Hero is in LP w/ T [img]/images/graemlins/heart.gif[/img] T [img]/images/graemlins/diamond.gif[/img]. Hero raises to 1.75, Villain smooth calls OTB.

Flop 2-way (4): 4 [img]/images/graemlins/club.gif[/img] 7 [img]/images/graemlins/club.gif[/img] T [img]/images/graemlins/club.gif[/img]
Hero bets 4. Villain raises to 8. Hero??

Thoughts about this hand and how to proceed. Comments on preflop/flop betting also appreciated.
