88 isolation in MP

11-handed live game at Western Fair.

UTG+1 is agressive, limps with many suited cards/connectors, haven't seen enough preflop raises shown down to have a good enough judge of raising standards.

MP2 is a loose young player, and appears to be on tilt at this point. He came straight to the table after a good run at blackjack, is very talkative, and might even have a couple drinks in him, although he is not drinking now. I have seen him raise preflop and then dump his hand on the flop a couple times now already. EDIT: This led me to believe he has loose raising standards and plays weak-tight postflop.

MP4 is an old lady who hasn't played very much poker (so she says, and judging by her play over the past 2 hours, its not at all unreasonable) and is generally weak-passive, and loose-passive postflop. She's been getting some help from the button, who is a huge table coach and was told off by MP2 a couple hands ago for giving the lady advice during her hands.

BB was a Johnny Chan lookalike and was wearing a Taj shirt.
