Let's make this birthday one to remember.

90 years old (Born on November 12, 1934)

Happy birthday to the legendary Leonid Stein, whose chessboard brilliance made even Soviet grandmasters scratch their heads in disbelief! Your dazzling victories throughout the 1960s—especially your three-time triumph at the USSR Chess Championship (1963, 1965, and 1966)—still leave us wondering if you secretly had an extra queen hidden up your sleeve.

Though decades have passed since those golden days of tactical wizardry and fearless attacks on kingside castles, we still celebrate how effortlessly you turned complex positions into masterpieces. May today's festivities be as timelessly brilliant—and perhaps slightly less complicated—as one of your unforgettable combinations. Cheers to a true king among pawns!
