FH on dry board vs tight player. How often does villain bluff here?

Naturally you don't beat any of villains value hands, no-one valuebets JJ or TT here, even KK is thin and usually I value bet that only against very fishy players or stations. So it's value or bluff, I like folding here. Flop I would just normally cbet this.

I also like the fold XC, XC then big bet by a tight player generally has so many value hands in his range that beat yours and as SS said the only hands you beat are JJ or TT which he with 99% likeliness would not bet here. The other way you could win this is by raising but again I dont see a lot of folds coming your way : ) you can also win by calling but since you dont beat his value betting hands, you could only beat bluffs but since you said he is a tight player, it is unlikely that he simply jumped at the opportunity to bluff simply because you checked (if he has any bluffs in his arsenal at all that is). I like the check on the river, after you get called on the turn you are finding yourself in pretty murky water here.

How often people fire triple barrel bluff in paired boards? Some might, but if you don't have reads/notes for that you should assume that it doesn't happen 99% of times.

His flop range is pretty wide, although the bet sizing is a bit big. On the turn when he continues to fire, alarms should fire. First question is "what is his value range?" For that the answer is 2, 99, KK, AA. Even with KK he might just check. Obviously, against his value range you have maximum of one out. Next questions is "how often he will bluff here?". He seems to be a reg, so he should understand stuff about poker and PLO. So he might think that you don't have nuts or "nuts" that often and plans to just fire turn and river and hope you fold. Or he can think that when you call the flop you have something, and it's not worth it to try to bluff you anymore. If your flop calling range is 2, 99, QQ, KK and AA, against that range it would be suicide to fire turn and river.

In my experience this turn bet is 99% for value in PLO5.
