$50 JJ, whoa wait, WTF?

BB is totally unknown, very first hand ever played with him. Please note that he insta pushed the flop. I doubt he was able to even see and digest what the flop was before pushing it was so quick. There are two people to act behind me, what it do?

Easy fold IMO. It's an overbet, the conditions are poor, we're hoping that villain has AK or ace-duece (in which the pot isn't locked up) AND that no-one behind caught. When too much has to go right... I fold it.

Easy fold I think. Making a note though obviously.

Is this BB's first hand at the table? I tend to look these guys up if they're buying in small, but that might be a leak.

say curse words and then fold.

Call me a donk but I call

I'm going against the grain here.

BBs first hand, he's insta-ALLLLLLLLLLLLL IN? You say he pushed so fast unless he's a bot he couldn't have read the screen? I just don't buy it that he has anything. I'd go so far as to say he has two unpaired, unconnected cards.

You aren't deep with the other players (100bb) and the board is pretty good (paired and no overcards or draws), I'm pushing to isolate the moron.

The only way you're in any trouble here is if one of the two behind you flopped something with 98, T9, a boat, quads or a slowplayed big pair. Unless either of the two villains are prone to cold-calling preflop with QQ/KK, you aren't worried about the big pairs.
