Later on in the 1960s, he played a newspaper game against grandmaster Paul Keres. Following a system similar to that adopted in the "Kasparov versus The World" match, readers would vote on moves and send them into the "Chronicle". Koltanowski would select the move actually played, and would award points and prizes to his readers for their selections. However, after about only 25 moves, Keres abruptly stopped the game and declared himself the winner by adjudication. Koltanowski disagreed and showed analysis which seemed to give him at least an even game. Keres, an Estonian, may have been ordered by his Soviet handlers to stop playing.
