Without knowing the size of the chip leaders, it is tough to say...In hand #1, I push 100% of the time there...I feel you have to make something happen here, you may have the best hand as well...An overcall probably dooms you, but I think it is the right play...

In hand #2 Knowing chip stack sizes is even more important here...I think it is a virtual coin flip as to the "right" thing to do here...A "read" is probably going to tell me what to do here, but other than that, I think I have to go with the hand meaning a call I think) I wanna see a flop here, and I know I need help......My aggression gets me into heaps of trouble sometimes, and that's why I am posting this first---Rip away boys and give us both all your thoughts...
