Donkin' at me.

[disjunction]

I'm pretty sure the correct play is to peel, if you've been sitting at the table with him for awhile and he hasn't stood out.

If I or he just sat down, I raise and take the free card because: (1) He may turn out to be a bet/fold type (2) People seem more likely to pull off a bet/fold when I first start sitting with them (3) Metagame. You bet I raise. (4) Information (with apologies to MM): I want to know what he's donking with. (5) I think there's a good chance my ten is live.
