[Closed] a hand that killed me :)

Well played. Flop and turn is standard value play. He could be 3betting the turn with a set, weaker flush, two pairs etc so it's an easy cap with second nuts. Capping the river would be a bit too much against unknown, his donk/3bet looks exactly like the nuts there.

You shouldn't post the results as they're totally irrelevant and might disturb the neutral hand evaluation.

I would cap flop for value and protection from lone A Would it be OK or not?

well spotted that a 3bet on the river is almost always the nutflush. for the short time you've been playing (assumingly) you are quite good in evaluating your relative handstrenght, according to your opponents range. most of the hands that you posted were played well. against a tight guy it's worth to consider whether it may be better to just call his donk on the river as you have already shown on the turn that you have the flush and donk on the river does actually always mean donk/3bet and as he can't have a J, Q or K high Flushdraw, it makes the nutflushdraw quite likely to be in his hand and thus calling is probably > raising but with no read at all, i'd raised the river as well!

@oly

i didn't get what you mean. you would cap the river or what? ;P

I said I would cap flop, not the river.

Since we have 2nd nut flush I wouldn't put him on a nut flush on flop but more likely on lone A , set or 2 pair, and I wont to protect as much as I can against these hands because they still have outs against me and they will certenly pay me off if they don't hit, and in most cases they wont hit. It would be also good against worse flush.
On turn he is not slowing down so I would start to believe I have most expensive hand and would raise/call, and just call the river bet.
I mean, after our cap on flop and raise on turn if he is still raising and betting on this kind of board I just want to see a showdown, I don't want to raise any more, either he overplayed his worse flush or he has a nuts.

Thats what I meant Now, is there a mistake somewhere in tought process?

Oly: imo 3-beting flop is mistake, because it can scare Kx, calling looks like c-bet and tells that You probably have draw (or even air) so induces bluff on turn.
