AK river spot 100nl

villian is running about 26/19 and is pretty aggro postflop. no other reads other than he's raised the turn after calling the flop 3/7 times. this could be an easy fold i'm not sure lately.

His range should be slightly stronger pre, because he called you COvUTG (not too too many low connectors), also he floated flop 3ways.
So i obv see him having some 45s/89s/T9s/9h9-JJ in his range that he might play like that, but imo (+we`ll have low flsuhes to call it down for the times we decide to bluffcatch, instead of Ax)
Also i dont see people getting out of the line on this specific turn, becuase he might not expect you to fold trips+ (which is what you`ll have most % time when you bet the turn, given that its pretty bad turn card for us to bluff on, so there are almost no (semi)bluffs in our range, and all our Ax are fairly strong given we were UTG PFR)
Its interesting to me, how often people actually do fastplay (esp non-nut) flushes on this turn in reallity, vs bluffing with potential bluffs. It seems to me that it would be correct to call that turn with a low flush normaly, when reg barrels..?

id just call if hes from anywhere in europe, russia, or south america.

I'd just fold the turn no matter where he's from.

The answer to this question can be determined strictly mathematically.

Sorry I have trouble with basic arithmetic, someone else can help better though.
