$2/$5 NL with 77

i have $1k behind. UTG+4 is somewhat loose aggressive and has me covered. (i've been playing with him for about 4 hours). He 3 bet me once (preflop) and I folded. He 3 bet me another time (preflop), I 4-bet and he folded.

I'm UTG+3 and i limp with 7♣7♠. UTG+4 raises to $20. SB and BB call. I close the action.

$80 8♦7♦2♥ SB and BB check. I bet $65 and UTG+4 calls. SB and BB fold

$210 T♣ I bet $180 and UTG+3 raises to $400. Hero?
