While the majority of the attention of the Chess World has been focused on the World Cup I have been focusing my attention on the US Senior, and US Junior, championships being contested in St. Louis, which is now considered a Covid “hot spot.” St. Louis County Is Now A ‘Red Zone’ For COVID-19, According To The CDC. A third wave of the COVID-19 pandemic is coming, the St. Louis Metropolitan Pandemic Task Force warned yesterday. (https://www.riverfronttimes.com/newsblog/2021/07/21/st-louis-county-is-now-a-red-zone-for-covid-19-according-to-the-cdc)
The hottest Chess spot in the USA is at the St. Louis Chess Club, where the intrepid boys, girls, and Men are battling it out over a Chess board in three separate tournaments, the US Senior; US Junior; and a completely separate “US Girls Junior Championship.”
Before the US Senior began I predicted the winner to be either Alexander Shabalov, or Larry Christiansen,

a man with whom I stayed up all night playing Backgammon, after he beat me handily at a simultaneous exhibition sponsored by Church’s Fried Chicken in the 1970s. I won the Backgammon battle. Larry kept looking at me with a look that said, “I beat this chumpy-lumpy like a drum at Chess. Why am I losing to the guy at Backgammon?” The stake was only a quarter a point, far below the stake for which I usually played, but it was Larry C., and Chess players don’t have much money, even those traveling the country giving simuls. Larry spent the night at the home of former Georgia Chess Champion Michael Decker, which is where we “rolled the bones.” Still, that twenty five cents would now be worth about two bucks, Chuck, if you get my drift…
Yesterday Larry had to face the Kentucky Lion, Gregory Kaidanov,

who had run away from the field, scoring 5 1/2 points in the first 6 rounds! He was a full point ahead of Larry C. at 4 1/2, who was a point and a half ahead of the four players with 3 points. Larry C. was in need of a victory. What do you play against an opponent who is obviously in form in that situation? You bring out “The truth as it was known in those far off days.”
