3bet Hand Replayer
This is less of a line check than a read check, so let me describe villain as detailed as I can.
BB is what I call a mouse or Tight Passive. He's a 20's or early 30's white dude who's pretty quiet and a regular at the casino. He plays pretty straight-forward and tight postflop, and somewhat tight pre unless he gets good odds to call. I've never seen him even attempt a bluff. He plays very passively preferring to call than bet or raise unless he has a lock on the hand. He does open up when he loses a stack (temporary tilt). He also opens up when his stack gets shorter. He shoved $200 into my $25 raise earlier with TT (I snapcalled with JJ).
My image is definitely aggressive and I change gears rapidly between tight and loose. Everyone at the table knows I'm capable of making huge bluffs, and some of the more passive players have adjusted by block betting into me on the river (which I'll bluff raise for fun sometimes). I do sometimes slowplay a bit (earlier, I checked flop and then double-barreled my boat into this same villain). If we're keeping score, I'm up about $400 on this villain in this session.
River, there's a backdoor flush, straight got there (for chop), and slowplayed or made boat is possible. Would you call?
