About A.Alekhine

I had see many chess player have different style while playing chess except Alexander Alekhine,one of the best history's attacking player,and is known ability to play creative and deep combinations.Until today,some of his famous combinations are so deep that even modern players and computers have not conclusively shown whether they are completely sound.This allowed him to find complications in positions that appeared quiet to most players.

In my question,what make him genius actually??

Vodka

ah, yes, my personal chess hero.  he practiced, long and hard, every day but still, he had a little something extra to propel him to the top.  great, great player.

He did it all while drunk.

yes he would often attack history and his non-famous combinations are known to be shallow and unsound

He also liked cats
