re: Poker & How did Galfond calculate this equity?
This is pretty basic stuff. He sees a lot of Laaks range as overpairs or 67 89 A6 A9 type hands. His little pair has a bit of equity as he has 5 outs to improve. Combine this with two backdoor draws (these are 24:1 each) and discount your outs hooking up an opponents straights, boats, or counterfeited hands and at best you are a 3:1 or 4:1 dog. So he had to ask himself what part of laaks range folds to a shove and how likely is that to happen... that's the harder part.
