The participants in this particular battle are Dawid Janowski (1868-1927) and Edward Lasker (1885-1981). The former, as noted above, played in a world championship match, losing badly to Emanuel Lasker. As for Edward Lasker (a distant relative of his namesake), he's reasonably well-known in American chess circles, as he lived the vast majority of his life in the U.S.A., but he's not as well known elsewhere. In 1924, neither player was a threat to win the championship, but both were elite players - neither man was there out of charity.
As for the game: I first saw it when I was in my early teens and maybe sooner, and I haven't forgotten it to this day. More than the games that won brilliancy prizes or the Capablanca-Tartakower rook ending (the one that's in almost every book on rook endings ever written), this game has stuck in my mind. That's because the players (especially Janowski) were operating in the realm of fantasy. Forget about correct, "professional" chess; these guys decided to go on an adventure. See it for yourself tonight - Wednesday night at 9 p.m. ET (that's Thursday at 3 a.m. CET) - and join in the adventure. You'll be glad you did.
