venetian 5/10 river fold.

[mj12]

I have been going over this hand in my head a bunch and just wondering if you guys think this laydown ( or other streets) is Ok.
I have been pretty tag, raising a lot pre but rarely limping.
I havent shown down any big hands or shown any bluffs most hands have ended on the flop/ turn that ive played.
villain sat down with 600 ( cap is 2000) , he is mid 30's clean cut executive hawaiin shirt looking guy. Seems passive. he limps a lot but doesnt play a ton of hands. He seems to c/c down mid stength hands. He has not been involved in any big pots and has not done anything agressive yet.

I am dealt red 54 in bb, get a bunch of limpers and sb completes. 7 see the flop.

flop is 763 2 spades.
I lead 50 and everyone folds but villain who limped in co.\

I lead 120, he hesitates. looks a lil confused a my bet and asked the dealer to check the amount, dealer says 120 he hesitates counts out chips for a min and calls.

I lead 200, he thinks for about 15 seconds and puts me all in for about 450 more. I fold
