DKarolis is a good reg, and really turning up the aggression on this FT.

ICM dictates I don't 4bet even if I think he's 3betting too much.... which he is. So IP I flat and I think this is fine.

Obviously calling on this flop.

He snap checks. And that raised slight alarm bells with a timing tell, as it wasn't something he had been doing. With that said I didn't know what to do here. I thought I very likely had the best hand, and I probably should bet for protection but in game I didn't want to face a check raise and have to fold because of ICM. So I thought I'd check behind and assess river. His range is very wide here and that's part of the problem I have here. It contains all sets, A4, and over pairs plus a ton of broadway. So I guess now thinking about it it's a clear bet as he's range is weighted to over cards? But bet folding here just seems horrid. Anyway!....

This is the major question for me. How does this river effect his range compared to a none 'scary' river say 5s. Does this Q add more bluffs and there for make it an easier call compared to if 5s landed? And what would you do in this spot?
