Akiba Rubinstein
After the war Rubinstein was still an elite grandmaster, but his results lacked their previous formidable consistency. Nevertheless, he won at Vienna in 1922, ahead of future world champion Alexander Alekhine, and was the leader of the Polish team that won the Chess Olympiad at Hamburg in 1930 with a superb record of thirteen wins and four draws. A year later he won an Olympic silver.
