i dont really like any of these raises.

especaily the one with 33. how do you "know" he has a big pair. his flop bet could be a cb, he could have ak, aq, he could have 66, tt, etc.

think about it this way. you are allready going to get good action from AA, KK, and maybe QQ NO MATTER HOW YOU PLAY IT, but most other hands fold. so why not play it in a way that gets action from other hands as well, such as 77, 99, AK.

raise on the flop is fine! just raise enough so he can at least consider playing a smaller pair. the only thing calling that bet of yours is a huge hand.
