Here's a tricky one on the river:
FullTiltPoker Game #197863599: Table Lamont (6 max) - $1/$2 - No Limit Hold'em - 2005/08/27
Seat 1: mrdixon ($177.35)
Seat 2: Mechanique ($312.85)
Seat 3: fergpm ($59.35)
Seat 5: SpeakEasy ($336.55)
Seat 6: THE ROC ($205.70)
THE ROC posts the small blind of $1
mrdixon posts the big blind of $2
The button is in seat #5
Read: Villain in this hand is fairly solid. Not wild and loose, not too tight. Seems like a solid player for a 6-seat table.
