Short and Sharp

Before getting into this post I should mention that Stockfish 17.1 has been out for a few days now. It’s only 20 points higher, but who wouldn’t like to have 20 points added to their rating? 
 
 
    The other day I was browsing some chess magazines from 1970. That’s 55 years ago which for many readers is more than a lifetime ago, but for some of us it doesn’t seem that long. 
    The US top ten players were Bobby Fischer, Samuel Reshevsky, Pal Benko, Larry Evans, Lubosh Kavalek, William Lonbardy, Robert Byrne, William Addison, Arthur Bisguier and Walter Browne. They are all gone now. 
    The top junior players were Ken Rogoff, Greg DeFotis, Camille Coudari (Canada), James Tarjan, Norman Weinstein, Eugene Meyer, Charles Koplik, Sal Matera, Charles Irvine and Steven Spencer. 
    Greg DeFotis passed away in Illinois at the age of 65 in 2017. I am not sure, but Charles Irvine may have passed away in Alabama in 2021. Steven Spencer died of lung cancer in San Diego in 2008.
    The Match of the Century yook place when a four-round, ten-board contest was played between teams of the USSR and the Rest of the World was held at the Trades Union House in Belgrade. 
    Two thousand spectators made up the audience. Based on ratings Bobby Fischer was to Board 1, but in what might be called the Surprise of the Century agreed to step down to Board 2 when Bent Larsen argued that recent performances should put him first and he refuses to yield on the point. 
    The USSR won the match by a score of 20.5-19.5. By the way, Larsen scored 2.5-1.5 against Spassky and Fischer scored 3-1 against Petrosian. 
    Fischer won big (by a 3.5 point margin) at Buenos Aires ahead of Vladimir Tukmakov.He also won at Rovinj/Zagreb ahead of Hort, Smyslov, Gligorić and Korchnoi (all tied). The Siegen Olympiad was won ny the USSR ahead of Hungary and Yugoslavia. FIDE formally adopts the Elo rating system. Viktor Korchnoi won the Soviet Championship. Bent Larsen won the US Open Chess Championship in Boston. Mikhail Botvinnik announced his retirement from competitive play. FIDE President Folke Rogard retired and Max Euwe replaced him. 
    Here is an enjoyable little correspondence gem by a couple of amateurs that I discovered buried in the back pages of one of the magazines.

  A game that I liked (Fritz 17)
