A
UTG raises to $0.25, MP folds, CO raises to $0.70, Hero calls $0.70, 2 folds, UTG calls $0.45
Flop: ($2.17) K 8 J
(3 players)
UTG bets $1, CO calls $1, Hero raises to $5.54 and is all-in, UTG calls $3.82 and is all-in, CO folds
Turn: ($12.81) 2 (2 players, 2 are all-in)
River: ($12.81) T (2 players, 2 are all-in)
Preflop: Not sure what to do. If I 4bet, I supose I would isolate myself against KK+. I think calling is fine. In the other way, the UTG looks like a fish and the CO looks like a maniac, so probably 4betting and calling shove would be a bit better.
Flop: Hit TPTK, so, according to preflop play, decided to shove because I don't want to see T, Q or J on the turn. If I call, I would have to call the the turn also, anyway.
UTG: 36/12/34 (VPIP/PFR/H)
CO: 35/27/13,3/286 (VPIP/PFR/3B/H)
We know each other, so was joking. 
We can think about those big sizings in many ways. It's clear that those players are not good because regulars don't make those sizings. The question is - is this a tell of a good hand or they are making those sizings with any hand they play. I didn't know that while playing the hand. It's safe to assume that this means a big hand, so fold would probably be fine, even it's always weird to fold AK. Anyway, in this particular hand turned out that the UTG is probably doing that with any hand, so from now on, I would call/3bet/4bet AK all day against him.
