Here's a question I'm hoping to get some clarification with. I'll start with an example from earlier today.

I was dealt JJ sitting at CO orbit goes around 1 caller and MP1 raises 4XBB. From what I know about MP1 is that he will only raise when he's got group 4 and up type cards. So my intial reaction is that he may have me beat, but I'm not looking to leave just yet. Everyone else folds and when its me I give him a little raise

Now I did this raise because after reading so many threads here and hearing that positions on things it sounded like this would give me an idea where I stand with him. However, many times when I throw that raise out I begin to feel a little committed to the pot and if I get re-raised I have a hard time throwing the cards away. Also I find that some of these guys will push AKo without any sign of even a pair on the flop.

So back to my story, I raise him, everyone folds and he goes all-in. Now I'm in this position where I'm not sure he has AQs, AKs or something worse like AA, KK, QQ. But now I feel like what the hell go for it your already in this deep. I know this is probably the wrong mentality but its the way I get on these raise battles.

I guess my question is, when is it OK to call someone's preflop raise when you to feel like you have a winning hand? Or is it never ok to call a PF raise if you feel you have the nuts and you should always raise to see how the person counters? And if that person counters how do you react?

Oh and the end result of my story was the board:[7s 8c Qd][Js][2c] he had AA and I won with the trip jacks...Phew!
