Well my question is how mutch should I Cbet on flop if I did not hit (I bet like 70% of pot) and how mutch when I hit set or other nuts on flop?
For example in this hand I think I shouldn`t cbet turn am I right? (because board was wet and any board combination would beat me,so right way was cbet flop and after this check/fold?)
Is there any standard lines cbet sizes?
Thanks for advice!

Correction I realised that I did not cbet 70% of pot this time ,but usually I do

what are you trying to accomplish here by betting the flop? I think that's a good starting point. what is your reasoning for betting 70% pot(in this case ~57%) on this board with 55?

Raise less pre, can also make arguments for jamming or flatting.
Check flop

Assuming the other players are recs, there is no need to balance. Bet flops you hit rather big, the wetter the more. Bet flops you miss and have no sd value smallish unless you know that particular player just won't fold to cbets (and/or turn barrels). Check quite some flops where u got showdown value like this one. Don't forget to bluffcatch small river bets
A huge bet on this flop does exactly the opposite of what u want to achieve: Pretty much all better hands continue and there isn't much to get value from with 4th pair. Sure u might fold out some equity but that's (prob) not nearly worth it.

i would call preflop on the button and set mine. If you had 10-13 BBs then i would shove. i don't like the raise preflop because it makes flops difficult to play when the pot is so much larger.

as played i don't like the flop raise. I think kj hits their range and your bet prob wouldnt get a bettr hand like jack x to fold.

Clear jam pre for 10x the dead money. Never 3x this kind of stack size - decent players will jam or fold even if you bet smaller so it's a waste of chips when you end up folding. Go for a 2x-then-call (some people like 2.25x) range and a 2x-then-fold range

In answer to your question, by default you should bet the same amount with both value and bluffs so they can't work out which is which.

People bad enough to flat the 3x will probably play fit or fold on the flop so your bet is fine (you can't often get 55 to showdown by checking 3 streets anyway and can quickly get overtaken so forget that your likely 5th or 6th pair on the river is "showdown value", just play it like two blank cards). Once called, just check-fold.

Agree with Lektor. If you are going to bet pre, 2.25 or 2.5 is better. Once they call, there is no reason to continue on this board. Keep your c-bet sizes the same (as Lektor says) when you hit or miss. I find the size of the c-bet to be dependent on what types of players are at the table. If they are tighter, I go for less, maybe 40%, and the looser the higher I will c-bet to either push them off, or punish them when I hit.

Check-Fold and move on to the next hand.
