Adjusting to opponents stack size

[rbenuck4]

5-10nl at Resorts in Indiana.

I just sat down two minutes ago from a must move and watched villain with J10s (spades) call a big bet on flop and turn with a flop of J43 with two spades, he hit his 10 on the river, and called another big bet in position only to be shown a set of 4's. His stack is 900, I cover. Other opponents in this hand have around 1500, I cover.

I have KQo in MP.

EP limps, I raise to 50, villain calls from button, BB calls, limper calls.

4 see the flop, pot is 205. Flop is Q [img]/images/graemlins/club.gif[/img] 9 [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img]. Checked to me, I bet 150, villain calls, everyone else folds.

Turn is 2 [img]/images/graemlins/spade.gif[/img]. Pot is $505. Villain has 700 left.

What's your plan? Also, what's the plan for river?
