1-2NL MGM Springfield AK on monotone versus check raise all in 250bb deep

Table 1 MGM Springfield by the cage. Villain looks like a young/mid 30s year old Spanish background bro. Lots of them at this casino. I may have played 1 session with him in the past as his face looks familiar or maybe it was his railbird friend who was familiar I'm not 100% sure. Anyways no real huge reads on this guy he's only just sat down at the table 5-10 min ago. He bought in for the max, 5 stacks of red, and I did too ($500). I've been bouncing around tables all day and have a stack of approx. 700 to start the hand and playing solid straight forward poker as I always do at this place cuz in my opinion there's no reason to try to run any fancy plays and bluffs versus the average 1/2 NL lineups at this place. It's New England; everybody is relatively well off and not afraid to put in some money to keep you honest if they have a decent holding. He won a medium/average size pot in his first orbit with good cards if I recall correctly; sorry I honestly don't remember exact hand he won but it seemed pretty standard/semi coolery and his stack is closer to the $600 range at this point I cover slightly. He has (at least) a little booze in the system, showing up with either a corona or a mix drink. I don't remember exactly as it was many months ago and this is just from memory. I believe I'd seen him tank tank tank and fold to a big bet last orbit so he didn't seen like complete 100% drooler with no fold button but he seems like the type of guy who isn't anything close to a nit either.

Villain opens to $20 UTG. This is a significantly larger open than average at this table and mostly any 1/2 table in the world. He seemed semi steamed from a recent hand so I'm not exactly putting him on the range of the average 70 year old nit-tag-reg opening 10x BB UTG of JJ+, I'd say he's a bit more like AJ+/88+ if I had to guess, but who knows. Anyways I look down at AKo no diamond in MP and decide to bump it up to $69. Folds back to villain and he calls quite quick.

K♦7♦5♦

He checks rather quick and I fire about half pot $74 or so with plans of value betting all 3 streets for smallish sizes, just enough to charge a raw flush draw slightly improper odds and just enough to keep a worse hand (QQ w/ a diamond...KQ....etc) in hopefully and get 70-90% of stacks in by the river but I doubt I'm good enough and he's bad enough to get that entire 100% of stack in TBH. Well I guess my plan blew up in my face as he quickly ships the five red stacks in the middle for a total of $505 if I recall correctly.

I tank for a minute, maybe two and table gets all upset and someone calls clock. In the mean time I'm trying to pry some info from villain asking typical questions like "what do you want me to do? do you want action? do you have a good hand? etc." He seems indifferent about whether I call or not I suppose and almost trying to goad a call from his body language/reaction.

I hate these spots against relatively unknown. There's a certain player or two at this casino that come to mind I would happily snap off with in this spot without any thought 90% of the time, but doing it against almost anybody else seems like very high risk and will be heavily behind most of the time.
