Preflop is standard,
Check on flop is OK I think too
My intention on turn was get fold mostly from AK. I expect bet from AA/KK somewhere on flop or turn.
River- I realy don t know, if can continue with bluff, his range is something like QQ, some KK, maybe AJs. Both flush drow missed, so I think that with AK I have too many bluffs there, I have AQs, KQs...

Maybe the most easiest play is back turn...

Thank you for any advices :)
