A little bluffing never hurt no one...

Speaking of steals and betting multiple streets:

Hero (BTN): $165.50
SB: $131.50
BB: $100.00
UTG: $70.00 - 0 hands.  Zippo.  Nada
UTG+1: $159.85

UTG posts a big blind ($1)

Pre Flop: ($2.50) Hero is BTN with 6s 7s
UTG checks, 3 folds, Hero raises to $4, 1 fold, BB calls $3, UTG calls $3
I go for a steal and am surprised to be called by UTG.  Odd play.  BB knows I love to steal & iso; he's a 15/11 / 4.9% 3bettor.

Flop: ($12.50) Th 3s 4h (3 players)
BB checks, UTG checks, Hero bets $7, BB folds, UTG calls $7
Okay.  Backdoor spade draw + gutshot that he won't see when / if it hits.

Turn: ($26.50) Qs (2 players)
UTG bets $10, Hero raises to $30, UTG calls $20
Spades come in.  Keep betting; I'm not sure I'm happy with my bet sizing here - I'd like it to be a bit more, but I don't want to make it such that he has to make a crying call on the river.  In retrospect, I think this is a good sized raise.

River: ($86.50) 9c (2 players)
UTG checks, Hero bets $30, UTG folds
For the remainder of his stack ($29).  Pure bluff for 3 streets.  GG sir.  Thanks for more than 50% of your starting stack.

Final Pot: $86.50
Hero wins $83.50
(Rake: $3.00)
