Hello, my first post so idk if this is the right place for a plo mtt hand.

20e buy in on ''an untracked eurosite''. The field was soft, except the players left are mainly regs. 15 out of 450 left, 2500e up top.

There's no way to convert the hand so I'll make it manually here:

Blinds 10k/20k. Hero has 500k on SB and villain 900k on BB.

Folds to me on SB with KK93 single suited. I have mostly limped and I limp now too, dry kings are okay to limp I guess. Villain checks.

Flop K95ss, I have top set + FD to a king.
I bet 25k to 40k, villain calls.

Turn brick K95(2). I bet 50k to 90k. Villain calls.

River K952(T), no flush gets there. I bet 160k to 190k, trying to make it look bluffy. This might be a mistake since it looks like I'm polarizing to QJ straight or air?

I leave 245k behind and villain snapshoves. I tank fold.

What hands can he check-call flop and turn with? I block kings and the 9. He could have Kx with a flush draw or QJTx/9QJx with a flush draw? He would raise KQJT pre obviously.

Should I use different bet sizes on flop/turn?
What to do on the river? in the moment I felt like not betting is too nitty since I had been bluffing in a few spots. Anyway I can't believe he would bluffshove when I bet almost pot and he snapshoved too.

Hope this was not too painful to read

Limp pre is fine.

When you block almost all value hands with kk9,it`s much more likely villain is on a draw.

I would bet bigger on flop and turn,at least 3/4pot.

I would be closer to check call this river or bet smaller,as played can not see him

ever bluffing there,really painful fold but seems right.
