raise more preflop with your premium hands. be more inclined to call an overbet all in push with a strong drawing hand like a strong flush draw. be less inclined to call an all in overbet with top pair top kicker. i assume he is making these overbets with his powerful draws and also his sets. very hard to play against someone like this who is good, because if you start calling with your draws he may start pushing with weaker made hands. maybe you should start playing like this. if i had the bankroll to do it i know i would at the 1k tables where people can fold.
