Mikhail Tal (1936-1992) of Riga was the world chess champion 1960-61. He was known for his swashbuckling style, chain-smoking and hard drinking. His sardonic humor is usually attributed to his lifelong battle with kidney disease.
If you're into chess, you'll find these humorous. Even if you're not, you'll find some of these humorous:
"If you wait for luck to turn up, life becomes very boring."
"There are two types of sacrifices - sound ones and mine."
"Chess is better than checkers. In the very least it has a more interesting cast of characters."
"...Just as one's imagination is stirred by a girl's smile, so is one's imagination stirred by the possibilities of chess."
“Many sacrifices don’t require concrete calculation at all. It is sufficient to only glance at the arising position to convince us that the sacrifice is correct.”
"The pieces must breathe deeply and with a full chest !"
“Extraordinarily tense, full-blooded struggles that are absolutely without any mistakes are only to be found in distant interplanetary chess tournaments.”
