Re: Two Live Overpair vs. Flop Shove Scenarios
 

Could use better information about the players, but as given I'd default to fold #1 and call #2.

The difference between being ahead of QQ or being behind KK, whichever is in the opponent's range, is crucial.

I don't like the bet of 4k in hand #1 unless you are trying to induce a shove. Bet smaller, like half pot. It makes Shania happy (I hate that phrase. Why am I using it?) to bet smaller, both with air and AA.

Results:

I was Hero in hand 1. The guy had been at the table only a little while, seemed to know what he was doing, I thought it was possible that he had played AA or KK this way, also possible that he was capable of making a move with some sort of draw. I was at a loss as to what to do until I saw something which I thought was a very good indicator that he did not want me to call, so I did. I think I would have called anyway, but I'm not sure. He said, "Nice call", flipped over 88, and caught a 7 on the river, gg me.

I was Villian in Hand 2. I was pretty sure the guy had AA or KK given the pre raise size, and just didn't think he'd be able to fold the hand, especially because the board was so drawy that I could easily be pushing a big draw. I also thought a smooth call would be overly suspicious. Of course the guy folded. I flopped the nuts with 6d4d, easy game when you know what cards are coming. Bummer that no one called behind me pre, I thought everyone would after I did. Would anyone play it differently after the flop?

Hand 1: good read, good call, bad luck

Hand 2: You flopped gin, unless the villian catches runner runner for a flush he's drawing mighty thin. Calling and letting him bet the turn and/or river seems like a good option. You might as weel take advantage of position.
The down side to this is getting your straight counterfieted
or having a flush card come which might kill any future action.
