AK from the SB
 

Thought this would be a good discussion to get going. This type of situation is one where I find myself slightly uncomfortable...

Re: AK from the SB
 

#1: Obvious & required raise. I'd maxe a 2xPSB. If there's 5 BB in the pot, I'll make it 10xBB to go. A very stiff raise.

#2: Either flatcall with the intention of betting the flop hard when you hit, or re-raise PF.
