Tough spot with no reads, I'll assume they are a reg as they bought for full and Bovada doesn't have an auto buy in option?

Their line doesn't make sense to have QQ-AA/6x as they wouldn't be over shoving so much unless they are REALLY BAD. Can't see any super nutted hands playing this way on what is quite a dry-ish board.

I'm calling here for that reason.

Top of our range, lots of draws and a random play makes this a call for me.

I would fold.

I agree with Harvie's reasoning about this not making sense, but I learned my lesson calling these massive overbets from 5NL players. Overbetting to 2.5x the pot is just rarely going to be a bluff imo. We need to be right a lot here.

Not sure he's ever going to be a reg either 3 betting a x3bb open to x5bb, so he can probably havea fair few 6x in his range too. I'm not of the opinion that just because he's overbetting he never plays 6x this way. Seen it way too many times.

I think this is a bit villain dependent. Sometimes in-game I'll go for a call as it's so weird. But the preflop 3 bet size. It can mean a lot (just a pretty looking playable hand, or it could mean AA, but if it vs unknown I guess we can make a fold because as said above, we have to be right a lot.

I don't think villain is a reg or has much experience from his play, and maybe they just think 'oooh big hand, I'm all in'.

Maybe he thought he was on Zynga poker.

On the hand I agree with the fold maybe with two pair + snap call but otherwise fold against the unknown.
