It is hard to know. What kind of plays has he been making before?
SHoving there is horrible either he has it or not. Most players like to try to get some value from their good hands and this is not the way to do it. So I might lean towards it being a bad bluff.

BUT, it's very expensive to bluff catch like this. I'd fold unless I had a very good read.(Unless I was just too curious. Sometimes I call just to find out what they have even though I think its -EV.He might bluff or think his two pair hand is good and you have like 20% to make a full house or quads)

I don't consider HUD stats as good read. 20 hands especially.. its useless. Also I'd pay special attention to this player and look to play a lot of hands with him

he can have 66 for value there so i’m not folding. Plus random spaz hands i think

think with fdraw it is more easy call(some guys are trying fold equity so hard with it), and you dont know he is nit. You can do equilab and put him reasonable strong range + add some spazz and combodraw.
When you call and see JT it is alright, all JT play this way

Happily calling vs. 45/5.

i fold

it's a single raised pot, he can have a lot of crap and I can have a lot of crap in his eyes as well potentially. we dont have crap. you cant fold. 45/5 is a 45/5 even in 20 hands to me. that being said, a shove is soo soo polarizing..... I think I still call and then blame it on bad run vs station. it has cost me dearly in the past, and then again sometimes it just feels like they are handing u money.
