Interesting hand there, Kraz. A lot of times I will just check call river here as clubs and 78 miss.

As played, I'm assuming he chose which card to show you? So, for value, he's saying he has Kd2d...maybe KJ or KK? But, I wouldn't expect him to play KJ or KK like this.

If he views you as a thinking player, he could be throwing a Hail Mary here with air by showing one. Typically when a player shows one they're looking for a call.

His line doesn't make sense. Especially with the given extra info, he's capable of making some movies. I call.
