This is the 8th hand of the tournament. thwet's bet and (PF raiser) jahinger's call both seem weak. PASSdaSUGAH had made a standard PF raise/Cbet/Fold on the first hand to lose 200 chips. I can't necessarily consider him a donk.

I've seen this type of push be several things... it could be a set/overpair/straight fastplaying on a coordinated board... it could also be A7, FD or middle PP... I also can't discount the possibility of one of the others left to act having a hand here...

So anyways, is this a good spot to accumulate chips early on from a donk or a good spot to lose 3/4 (or more) of my stack on a reckless gamble?

Comments on PF and flop action are welcome, though I think both are fairly standard...
