$20 -> $1000

Two handed I think I can bet the flop for value when villain checks the flop at 2nl, 3 handed I think this is the only thing to do. Turn I'd usually just raise but the bet is so weak I don't want to push him off any hands and the blind can come along too. River I didn't like calling but villain must do this with enough Kx that it makes up for the times he has a better full house/quads.
