A couple tough hands...help please, thoughts?

[coolmoedee]

Hand #1
Villain has been aggressive but not showing any hands down. No good reads.

6 players

SB with $227.20.
BB with $165.25.
UTG with $142.30.
UTG+1 with $227.
CO with $201.95.
Hero is Button with $201.90.

Converter

Pre-flop: (6 players) Hero is Button with Q Q
3 folds, Hero raises to $8, SB calls, BB folds.

Flop: 8 6 8 ($18, 2 players)
BB checks, Hero bets $14, BB raises to $28, Hero?.

Is this always an 8? If I call and he bets out like $50, is it a fold then? Thoughts?

Did he miss his flush draw and now he's trying to buy it? Do you ever call here?

it always takes a few bumps for anyone to give some help.

1) I call this always, and raise sometimes, depending on if villain dumps with a pp here.
2) This really depends on villain, he could have played a wierd set here, this call is close but the time he took to call the turn bet, and go allin on the river would help a lot.

Hand 1 isn't usually an 8 - in my experiece a huge part of his range is a lower pp trying to feel out where it's at or maybe even air.

Hand 2 is the kind of hand that needs reads. You don't really beat anything but a bluff, could be a missed fd, 44, or any other weird [censored]
