Big slick cash hand

[Ciso_B]

Ok, I'm pretty unsure of whether i misplayed this , if its standard or what. So need some thoughts.

Background - I'd been at the table 34 hands,I had played pretty agressively up till this point,but hadn't really seen this guy get involved , so no notes really.

Here's the hand -
