Look also this skull. Look masculine jaw and wide frontal skull.
And this as well, Mikhail Tal.
Skull shape of Carlsen and Kasparov + bonus skull Aronian
Sort:
By looking at these masters, it is clear that there is a certain amount of testosterone involved in highest level of chess. These masters are all serious representatives of masculine facial characteristics. A result of good testosterone production, and as we also see: No conversion of this testosterone into feminine version that makes male baldness. All top players have good amount of hair in their prime.

What part of brain is used during chess? I can tell only by looking at these masters: Front part.
"Studies show that the brains of people who play chess are significantly different than an average brain. For example, grandmaster chess players have more activity in their frontal and parietal cortices, areas of the brain that focus on problem-solving and recognition."
Their skulls look to be same shape. Is this skull shape best shape for chess? Should chess select new chess prodigies based on this skull shape, and is future holding FIDE scolarship for personalities of same skull shape? Look how masculine their skulls are, yet big frontal room for extra brain capacity, which sets them apart from regulars.
I am also interested in Levon Aronian's skull. It seem to hold brain larger than median brain. Do you agree? Yet his jaw is not so wide as Kasparov's and Carlsen's. Aronian has more babyface, but bigger room for frontal brain.
What part of brain is used during chess? I can tell only by looking at these masters: Front part. Or do you have evidence of other part being used?
