I have seen that minraises pre (especially one with 40/4 stats) are normally KK+ at 25nl. I would play it a little more passively esp. not knowing too much on how the villain plays postflop. I'd c/c reasonable bets on turn and river.

call and fold to any substantial river bet.

If I call that bet about half my stack will be in the pot. Can I really call any riverbet at all without improving?

And if not, why call turn?

I just love CO's play preflop, on the flop, and on the turn. Actually I'd like to punch him in the nose. Anyways, he bet the minimum preflop, bet minimum on the flop and called a raise then FINALLY he puts in some real money even though its another minraise. Do you really think he has a bluff or QJ/KJ? Probably not so fold.

pretty trivial fold

why call isf
