Longest game of correspondence chess
South Africa

Dr Reinhart Straszacker and Dr Hendrik Roelof van Huyssteen (both ZAF) played their first game of correspondence chess in 1946. After 112 matches, with both men having won half the games, their record play of over 53 years ended with the death of Straszacker on 13 October 1999.

The two men eventually met in 1969. After their first two games, the pair would have four matches on the go at the same time.
