Wierd spot v. iRockhoes

[the_dal_kid]

Ok for some reason I can't find the hand in my PT database because I think it screws up when I go into the time bank but the hand went like this:

Full tilt NL 10/20 (6max)

I have a bit over 2k and so does iRockhoes.

I raise to 70 in MP with AKo and get called by the guy to the left of me and iRock who's on the button.

flop is 664 rainbow, I lead for 185, player to my left folds and button calls.

Turn is 4. I check, iRock bets 300 and I call hoping to put in a little bluff on the river.

River is K, I check and iRock shoves for the rest of my chips...

Comments on all streets appreciated.. is this just a "read dependant" situation???
