Villain checks, Hero bets $20, villain check-raises all-in for $150 with a loud, theatric "bet everything", grabbing two handfuls of her chips and slamming them down on the action line.
Hero now faces $130 to call into $203 pot.
Reads on villain:
* She's capable of playing hands big preflop. A lap ago, a weak loose player limped on the button on her BB for $2, she jammed $35 in preflop, got called, and wound up busting by check-calling the flop and jamming the turn with AK on a 4-T-J-K board by the turn and running into AQ.
* She's capable of slow playing big hands. A few hands after this one, she called a raise in position with a small pair, flopped bottom set, and just called the flop before shoving the turn -- and running into top set.
* This outburst of hers was the absolute first time I had seen her, in about half an hour or so, bet or raise with anything but deliberate motions. It's also the first time she vocalized her bet; her all-ins prior were just silent.
* I don't think she was particularly attentive to my image, which would be TAG mostly with slight attempts to mix things up.
I'll post my thoughts later on how I read the situation but I welcome people's feedback.
