Table 1; Hand One: Definately a fold. Easy. Blinds are really low and with retarded Party Poker players they can have anything like KQ - KJ - QJ - K10 and they are far too likely to hit their overcard. Fold IMHO!

Table 2; Hand Two: Harder decision. With the villain pushing allin again he is likey to have anything from KQ and on down like in Hand One. This early I dont know if I want to take a coinflip for my whole stack. Thats just me tho, I am on the more conservative side. I fold in this situation as well since you only have 75 committed and there is no reason to risk your whole stack on a push coin flip.
