1 is hot.

For 2, let me see if I can guess your reasoning. You don't bet flop because MP is loose and aggro and will often raise you with nothing or call.

You hit a Q sweet. You are wondering why the aggro MP didn't bet the flop and fear he might have an ace. If not there's a good chance he'll bluff it this time around. If you are ahead these guys are probably drawing pretty slim and the pot is small.

Nemesis bets the river. Hmm. I'm not exactly sure what he could have here. I don't think he would value bet a 6 or a 7 here. I think he would instead induce a bluff from the aggro button. I would also guess that he would bet a 6 or 7 on the flop or turn a lot (well I guess that's what I think a good player would do. Maybe not Nemesis...). Therefore I think his most likely hand is a bluff or an ace that went for a checkraise on the turn for some reason. Therefore I would call.
