this thinking is flawed cause it needs good players who dont bet K,T because "it is turning showdown hands into bluffs" which is a concept not very well understood by fish

Cbet flop smaller, cbet turn larger, probably c/c river; depends on river sizing of villain

c/f otr means you're losing to Ax a ton when villain bets it.

So we're betting to stop villain from betting? That doesn't necessarily make it wrong to bet, I'm just clarifying.

If you really think villain has a lot of Ax hands in his range, in addition to his Kx, and that these represent the bulk of his range, you should prob consider attempting to overbet bluff villain off a chop, in addition to c/c, b/f, and c/f.

I think blocking Ax bets is part of it. I am betting here because I think every other option sucks. even if the bet itself is not making us more money I think it still is better than c/c where we are either chopping or losing. and better than c/f because we will often fold a chop. as for overbetting, I don't think the cost of getting caught by flushes and trips is worth trying to bluff villain off a chop, esp that most fish can't fold aces and we have no idea what kind of villain this is.

have you considered c/shove?

Pre fine
Flop smaller
I bet the turn almost always when I improve
Bet fold the river slightly bigger (caveat I didn't really look at stacks)
