NL500: KK overpair 3bet pot 3flush turn low board 140BB deep

[Janis N.]

NL500 6-handed.

Hero is UTG+1 with K[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/heart.gif[/img] and $696.

BB is good aggro 25/22/3.16 multitabling SLAG over 681 hands and covers. I just stacked him on another table by fake-blocking quads on the river (he had 2 pair there). Seems solid.

Hero raises to $17.50, 3 folds, BB raises to $60, Hero calls.

Flop 8[img]/images/graemlins/club.gif[/img] 4[img]/images/graemlins/club.gif[/img] 5[img]/images/graemlins/spade.gif[/img] ($122.50)

BB bets $93, Hero calls.

Turn 2[img]/images/graemlins/club.gif[/img] ($308.50)

BB bets $185, Hero shoves ($360 for villain to call)...?
