Why do You check- call flop with 2 pair? Is K2 a hand you want to go 3 way with?
Why do you check turn when the A hits?
Why do you bet so large on the river? Where does K2 rank in the range of possible best hands on that board at the river?
What does that bet look like to our villain?
What would villain be expecting us to fold?
Pot 1.2 call .38 are you folding to often? Does villain know this?
Have you taken similar river action and folded?
If villain thinks we are bluffing why shove? Do good villains expect folds to those pot odds?
ICM considerations.
Does this good player not see 2 short stacks and that a call keeps villain in first place if they lose?
Why would villain run a big bluff here?
Why would villain check raise one pair Ax? If they have an A it is less likely you do so why not thin value lead the river?
If you call and win this pot villain just made the chip leader to their direct left.
Would a good villain take a high risk play and do that?
Hope this helps
