Good semi bluff by villain?

Not sure why I'm not fully stacked, and this kinda f*cks up the play for me....but I think its a relativly interesting spot.

I raised 5x the blind cause I'm OOP. I'm not so interested in my betting, more his. I thought at first when looking at this that his play was bad (and the call pre is)...but....Is his raise on the flop a good play? - is it a good semi-bluff (i'm reading The Theory of Poker :? ), that then sets up the odds to call my push for the flush (he had Kc, 5c)?

And did I play this correctly?

Apologies if this is just a standard situ.

if we are getting it in id rather call then call his shove on turn. this is fine tho if he will call with lesser PPs

preflop his call is very weak, and as played its not even a great semi bluff as hed be more inclined to checkraise with an ace rather than lead for fullpot. If id been villain and had been stupid enough to call pre in the first place id just checkraise hoping to get rid of bigish pairs and not minding to much if called as id still have decent equity. O and you played it fine.
