deep 2-4 limped hand

[gomberg]

Playing other day at a 2-4 table w/ about $1300 and villain behind me has about $600. I'd been bullying the table and limp late middle after some others with AdTd. Villain limps too. Tons of people in preflop...

Flop is 4dJd9d (i like flopping the nuts [img]/images/graemlins/smile.gif[/img] )

I bet out $25 (most of pot), villain calls - everyone else folds.

Turn is 5s.

What's your plan to get the most money in on the turn / river?

Some background info on opponent: Pretty aggressive if senses weakness. I've bet him out of some other pots with overbets - 1 a river bet and the other a turn check-raise. Can sort of sense he wants to pick me off...

Knowing that info - what would be the best way to get him to commit?
