A Maze of Complications

    
When it comes to World War II one rarely thinks of Cuba, but the country became involved in 1939 because of its geographical location at the entrance of the Gulf of Mexico. Havana's role as the principal trading port in the West Indies and Cuba's natural resources made it an important participant in the American Theater. 
    Consequently, Cuba was one of the greatest beneficiaries of the United States' Lend-Lease program. Still, Cuba did not declare war on the Axis powers until December 1941, making it one of the first Latin American countries to enter the war. Cuba lost six merchant ships during the war and the Cuban Navy was credited with sinking one German submarine. 
    Before Cuba got fully involved in the war, there was a tournament held in Havana toward the end of January in 1940 that aroused great interest, but only in Cuba. The only major chess magazine in the U.S. in those days was Chess Review and despite the fact that Isaac Kashdan who was one of the country’s top players (along with Samuel Reshevsky and Reuben Fine) won the tournament it received scant mention and only a few games survive. 

    The event was held in one of the mo st beautiful buildings in Havana, the Centro Asturiano. During the evening tourists watched the games. The players we re entertained by various government offices and they were taken on outings by the city’s notable citizens. 
    In the following game Kashdan defeats a player known only as “Paz” in a game that at one point had a maze of tactical possibility that never happened. I was unable to locate any information on Señor Paz, but his play in this game was quite impressive ans he made a good account of himself and nearly succeeded in holding the formidable Isaac Kashdan to a draw.

  A game that I liked (Fritz 17)

As for black's extra P, due to the blocked nature of the position and his cramped pieces he has little chance of putting the P to good use. Five Shootouts were uneventful draws.}) 14.

In Chess Review magazine an unidentified annotator called this a positional error because black's Ps are all on the same color as his N which means it is very limited in scope. He added that in addition after the exchange black's P on e4 is very weak and will probably be lost in any resulting ending.
