UTG rec; Fellow CO is tight Reg

I actuallyregret 3betting it for a slightly higher % since my postions isn't great. From BU I can pure 3bet vs some recs.
Vs CO size I have to flat a lot; My idea about his size that I need to flat more and shove at the same time. If I'm flatting here too much liner range it is super good for him as his 4betting range is super linear maybe (TT/JJ+; AQs+,KQs; some low wheel aces) so stuff like ATs/KTs/KJs probably still folding.

Any flop is pretty much great for IP as caller have plenty of stuff always; However I should be raising nevertheless and best bluff combos is obv. my hand/89/88c type of things

Turn can jam actually but I dont mind any.

River I quicly follow through his range (AK - 8 combo, AAc - maybe 3; KK -1 ; Flushes - 2-4; QQc - 3 I need 30% fold equity and thats 6 combinations - AA/QQ I suppose should be folded here. At the same time I was thinking my bluffs - honestly I doubt that I can have any so even his AK is pretty much hope to lose/chop
