Lasker and Tarrasch. The first pic must represent the Happy Days, when they were on speaking terms. The second pic is from their long-delayed match for the World Championship. By 1908 Tarrasch was well past his best chess but somehow he never was able, or willing, to arrange a match with Lasker. It's too bad for in the couple of years before 1894 (when Lasker beat Steinitz for the title), Tarrasch had won four big tournaments in a row and was generally considered the strongest player. By 1908 his chances had evaporated, especially against the younger Lasker. Tarrasch despised him so that at the opening ceremony Tarrasch refused to talk to Lasker, only saying:"Mr. Lasker, I have only three words to say to you: check and mate !" [wikipedia]
He needed more opportunity for those words as he lost +3 -8 =5.
Bogart has a try at a blindfolded Kolty.
