thanks guys, i have been sticking to your advice to always stack off with KK and usually it works out for me. but there are times when my gut is just screaming at me to fold, here's an example from today:
Stacks:
UTG - UTG ($4.78)
UTG+1 - UTG+1 ($7.18) VPIP/PFR: 20/16
UTG+2 - UTG+2 ($6.49)
MP - MP ($3.93)
MP2 - MP2 ($5.00)
CO - CO ($5.00) VPIP/PFR: 16/13 3B: 6
BTN - Hero ($5.86)
SB - SB ($5.00)
BB - BB ($5.00)
Preflop: ($0.07, 9 players) Hero is BTN with Kh Kc
1 fold, UTG+1 calls $0.05, UTG+2 raises to $0.25, 2 folds, CO raises to $0.82, Hero raises to $5.86 (all-in), 4 folds, CO calls $4.18 (all-in), Uncalled bet of $0.86 returned to Hero
Flop: 9s 5d 5h ($10.37, 2 players, 1 all-in - CO: $0.00, Hero: $0.86)
Turn: 6d ($10.37, 2 players, 1 all-in - CO: $0.00, Hero: $0.86)
River: Th ($10.37, 2 players, 1 all-in - CO: $0.00, Hero: $0.86)
Total Pot: $10.37
CO shows Ac As (two pair, Aces and Fives)
Hero shows Kh Kc (two pair, Kings and Fives)
CO wins $9.94
I have about 200 hands on both guys, and it really scared me facing a 3B to an EP open between two fairly tight players. either one of them could have the bullets, especially the 3better. as i said, my gut was urging me to fold, but my brain was saying "bro it's standard to go all in with KK preflop, get it in!" in the end i went with my brain, and maybe my brain was right and it was just a cooler, but i can't help but think of how often these situations seem to crop up where i'm behind with KK in spots like this. it seems like i have KK vs their AA much more often than vice versa.
