SB: $51.00
BB: $52.05
Hero (UTG): $54.00 - I'm a 18/16 / 41%steal / 5.9% 3bet / 2.0 AF / 94 hands at this table
UTG+1: $33.85
MP: $78.05
CO: $50.00 - 26/7 / 19% steal / 0% 3bet / 1.6 AF / 133 hands

CO posts a big blind ($0.50)

Pre Flop: ($1.25) Hero is UTG with Ah Ac
Hero raises to $2.25, 2 folds, CO calls $1.75, 3 folds

Flop: ($5.25) Th Qs 8h (2 players)
Hero bets $3.50, CO raises to $8.50, Hero calls $5
Not a great flop, but let's see where it goes...

Turn: ($22.25) 3c (2 players)
Hero checks, CO bets $12.50, Hero calls $12.50
I'm still not convinced he flopped QT or better, but an OESFD is certainly possible on this board.

River: ($47.25) Kh (2 players)
Hero checks, CO bets $26.75 all in, Hero requests TIME, Hero folds
By this point, I have to be in terrible shape.  KQ gets there, Hearts get there, Straights get there.  Any other card in this spot (particularly pairing the board 3's or 8's) & I snap call / fist pump.  This is the *SINGLE WORST* card in the deck... with the exception *MAYBE* of the 9h which is probably worse...

Final Pot: $47.25
CO wins $44.90
(Rake: $2.35)
