GM George Koltanowski, simply known as Kolty to his many friends, was the most passionate chess player I have ever met. He was always sharing his love for chess through his daily San Francisco chess column that ran for over five decades straight. His blindfold simultaneous exhibitions set world records and many new chess fans were created every time Kolty performed his famous blindfold knight’s tour while reciting the audiences’ addresses/phone numbers instead of square names. Koltanowski breathed life into California chess and we are still thriving because of it.
In the position below, Koltanowski uses a pretty move to conclude his game winning combination over Erling Tholfsen from round 9 of the 1928 Chess Olympiad. Can you white’s winning move?
