I would make it $250 then push turn if called. If he reraises flop then I would prolly call. I like to play these pots though b/c most of the time they will fold AA or AK, but even if they call its a coinflip, the only thing to worry about is a set. Without any read on the other player though it would be a little risky. Most of the time though I will be putting all the money in on the flop or the turn. Perhaps not the best play but its a good way to mix up your game with little risk. Curious to see what others will dd.
