NL 100 - Trips top kicker, facing weird overbet

[YKMM]

No reads on this opponent, play is standard? Despite the large flop raise, I feared that a 3-bet will make opponent fold many hands.

Wow, the turn sucks, but you can't fold.

What was he thinking? Was the 48 a misclick?

I might have just pushed on the flop. I can't imagine 77 playing this way, and a 6 is going to call. You might fold a higher pair, but that wouldn't bother me too much.

I really wonder if it was a misclick?
