way too many scare cards that can come on the river, and if he does have AA/KK in this spot after playing it like this, I doubt he folds to a push. I like to get it in here, any card that makes a 4 card straight, or a heart, or sometimes even a AKJT might be action killers (either you slow down if an A or K comes and he slows down if a J or T comes since he beats nothing in your range if he can do any hand-reading at all).

A more interesting question might be what you do with 444 or even 333 here (333 after you take a shot at the pot on the flop I guess). 1000 bbs deep is pretty sick!
