1) As has been said, AJ and AQ aren't great EP raising hands early in an SNG, as most flops will miss you you'll be out of position. This is especially true of the tiny starting stacks on Party.

2) I, for one, always fire a half pot continuation bet. Always. I feel this makes it impossible to read if the flop hit me or if I have a pocket pair already. I'm going to take the pot down better than 1/3 the time, so the bet turns a profit, plus the times I C-bet a missed flop get me more action for the times I don't miss.
