Unless the $55s at Party are drastically tighter than the ones at PS, I say you have to call that early in a tourney. Unless the board is a 4-flush or straight, or you have a read on a rock, I don't think you ever go broke betting trip-aces/J kicker early in an online SNG.

Looks like a defensive low flush bet. But the possibility that it isn't, and the decent outs you still have, make it a profitable play IMO. Outs + random early idiots = call. Then again I like to push things early, then move onto the next SNG if it doesn't work out, or tighten up if it does.
