NL50 Big river bluff v tight player

[bluffbetter]

Villain is 10.3/10.3/7 over 39 hands but his flop/turn/river aggression factors were 0/1/0 so I guess alot of the 7 stat comes from the fact he raised in every pot he entered, so it doesn't seem a very good stats to use. But somehow his postflop aggr is 3, but how do you get 3 from 0/1/0?

I hardly ever make big multi street bluffs and I play something like 21/12/2 I thought I'd have a go at bluffing here, but to be honest I didn't think through much about exactly what range/or hand I might be representing, but I did think his turn bet looked a bit weak, if he had bet more on the turn I would not have bluffed. Thoughts?

lol i dont really like any of this play firstly why are u just calling pre flop?? u should be raising with AK here imo. secondly why are u calling the flop with Ace high? if you plan to carry on u should be raising here to gain some FE... after that your hand turns into a pure bluff

The reason I didn't reraise preflop was because at the time he was something like 3.4/3.4/x over about 29 hands and I thought he may well have a big pair, and then i made the bad decision given that earlier one that his turn bet looked weak and then I bluffed. But I think my initial thought that he could only have a big pair was wrong because I guess he may well still raise every pair and AJ+ preflop and may just never steal or not have had the chance. But I'd still like to hear peoples views on whether this is a good play or not, because obviously if I had something weaker that wasn't a reraising hand then I could bluff with that and the line would be the same.

Maybe I should just give up after he calls the turn raise.
