We have some history with villain. He is unpredictable player, capable of making crazy moves, but generally he is quite solid.

Is this an easy laydown? I put his range on 77-99, A7+, JT and I was 4 to 1 against this range. Mix in some bluffs and maybe he wouldn't do it with AT or AJ so it becomes a fold. I posted this hand because I think I discovered a leak in my game, that I tend to call way too much in spots like this one.

I posted this hand to figure out if I can expand his range, but I don't think so. I want to figure out if this is a tough or an easy laydown.
