Chess In the Marines Corps

    
It was 1967, a significant year for pop culture with many notable events taking place. Hot cars were Ford Mustangs and Pontiac GTOs. I knew a Navy Dental Technician at Camp Lejeune, North Carolina who owned a GTO that he raced at the drag strip in Holly Ridge which is located several miles south of the base. 
    A couple of us were sitting in front of the barracks one night watching him laying rubber up and down the street. It ended when the transmission blew sending shrapnel our way. I don’t know what GTO really stood for, but he used to say it was Gas, Tires and Oil. 
    Besides the Beatles, bell bottom pants were all the rage; I never got into either. On a sad mote, astronauts Gus Grissom, Ed White and Roger Chaffee were killed when a fire broke out in their Apollo spacecraft during a launch pad test.
    Opposition to the Vietnam War was growing and large-scale anti-war protests took place throughout the year in places like New York, Los Angeles, San Francisco and Washington, DC. 
    I was discharged in July and during that month and August race riots erupted in over 150 US cities. Race was not an issue in the Marine Corps. There was, however, a big fight in the NCO Club on the base that resulted in the Base Commander shutting the club down for a week or so. It had nothing to do with race, just some drunk Corporals and Sergeants getting into a fight. Fortunately, I wasn’t there that night. I might have been playing chess. 
    Until I reached “short-timer” status chess was the furthest thing from my mind. There was a chess club on the base, but the players weren’t very good. 
    In my final few months I was assigned to Headquarters Company, 2nd Battalion, 2nd Marines and was watching television one night when a guy showed up who was with one of the grunt companies (infantry, I think the Army calls them) from down the street and he heard I played chess. We used to get together a couple nights a week and play. That was several weeks before I got discharged.
    I don’t know what ever happened to him, but at least he didn’t get his name on the Vietnam Memorial Wall. A Google search of his name turned up dozens of people with the same name so tracking him down was impossible Only four of our games have survived and this is the best one. 

  A game that I liked (Fritz 17)

Another h-file Attack

    
While browsing the other day I stumbled across the following game which also contains an attack along the h-file. The winner was. Guillermo Vassaux (June,1909 – May, 2006) od Guatemala; he was a player, chess teacher and writer who won the Guatemalan Championship fourteen-times between 1934 and 1973. 
    Vassaux was one of the founders of the Guatemalan National Chess Federation in 1939. In 1953, he was called one of the three great Guatemalan chess figures of the time. The other two were Enrique Hidalgo and Carlos Enrique Salazar. Vassaux won the Guatemalan Chess Championship fourteen times from 1934 to 1973. 
    He participated in the Chess Olympiad once, representing Guatemala at first board in the 8th Chess Olympiad in 1939 in Buenos Aires, scoring +5 -8 =2.
    Vassaux authored three chess books and wrote a regular chess column in the Prensa Libre from 1974 to 1991. During that time he also ran a chess program Ajedrez bajo los arboles (Chess under the trees) a park in Guatemala City. His students included three future Guatemalan champions. He was awarded a Medal of Honor by the Ministry of Culture and Sports and the Presidential Medal shortly before his death. 
    His opponent was John Morrison (1889-1975). Born in Toronto, e was Canadian Champion in 1910, 1913, 1922, 1924, 1926 and 1931. A game that I liked (Fritz 17)
