Thing is, people have argued about passing up on edges ranging from 60/40(common) to as ridiculous as 80/20 (GambleAB post), and by doing that the only person you are going to "outplay" is yourself. A GENUINE 50/50 situation has been debated before, and Mat shows us how much of an edge you really shouldn't ever be willing to pass up on, no matter your skill level. People don't realize how big those "small" edges actually are.
