If it's his standard, I'm probably shipping.

If there's no history or something he doesn't usually do just fold.

With no reads I'm OK with folding here. This sizing is unusual and is typically weighted towards stronger hands in my experience. I would be very keen on analyzing all spots we've seen this villain get to showdown though and taking notes accordingly. If we see him do this with dumb stuff then we can adjust accordingly. It's rare that I look into specific villains showdown tendencies but vs this guy it is worth it.
