You have about 14 behind on the river, right? Pepito is giving off one serious 'I'm full of crap' vibe. So looking him up is definitely an option. I mean, who plays their big hands this way? He loses tons of value when you check it back flop and turn, like you easily could have, and the river shove says 'go away.' IDK, it just doesn't add up. If he has a set, take a note.
