The critical spirit is one of the most necessary virtues to be a chess grandmaster. And one who always stood out for this is the Spanish Lluis Comas, born in 1971, world champion for children at the age of 13 and dedicated as an adult much more to being a coach than to competing. It is significant that the title of his book is “Risk Lies in Chess”.
The game that this video glosses illustrates this virtue very well. Comas sacrifices a knight in his twelfth move and soon after the queen to achieve a devastating attack, beautiful and very instructive at the same time.
