[Cooker]

I would say he probably has a modest pocket pair, but maybe even as high as TT or 99. The preflop play is so weird that there is a decent chance that he is doing something totally stupid though. Still, I think he probably wanted to try and flop a cheap set in a multiway pot, but when it became HU he thought he probably has the best hand and should raise. Of course his raise sizing is stupid.

I would have led for the pot on the flop and folded to any further aggression on his part. I wouldn't be surprised to see 55 or 66 here depending on how aggressive he is postflop. Looks like he went either continuation bet/spike set on turn or slowplay flop/hope you have a king and really milk turn. Of course he could have 99 and just be trying to push you out on the turn. As played on the flop, I would fold the turn.
