Counting Pieces

 
     A mental image is a mental picture of an object or event...or a chess position. We form mental images of all kinds of things: faces of familiar people, the location of the furniture in our homes, etc. This ability to hold and manipulate mental images helps us perform many cognitive tasks, including calculating chess variations. 
     Mental images can also lead to solutions when it comes to solving problems. Albert Einstein used a mental image in developing his theory of relativity when he pictured in his mind what it would be like to ride a light beam at the speed of light. He later said that words played no role in his creative thought; instead, he created mental images. 
     Chess players know something about visualization. It's the skill used to form mental images of future positions. Strategy and tactics require creating mental images and the move selected is played because the outcome has been visualized. It works that way for all players, but, of course, the stronger the player, the better they are at it. 
     However, as we will see in today's game sometimes calculating and mental imaging can go haywire even for masters.     
     In 1970 the US team captured the World Student Team Championship that was held in Haifa, Israel. The team was made up of Kenneth Rogoff, Andrew Soltis, Michael Senkiewicz, Richard Verber, James Tarjan and Marc Yoffie. 
     Although winning the event by a single point meant every point and half point was critical, the one game that gave the team the championship was one that, well, was literally given to them...it was Richard Verber's win over the Austrian player Werner Mikenda. 

Against Austria, at the beginning of the fifth hour of play, the US was losing 2-1 and things looked bad. In Verber's game he had a poor game positionally and if he lost the US team would most surely be eliminated from the race for first. 
     Out of desperation Verber began to complicate things and in the end a miracle happened...Mikenda miscounted the pieces on the board and resigned in a position in which his winning chances were quite good!
     Senior Master Richard Verber (June 3, 1944 – December 10, 2001) was long one of the strongest players and most prominent chess organizers and teachers in the Chicago area when he passed away at the age of 57. A National Tournament Director, Verber organized many important events in Chicago.
     As a player he represented the US three times in the World Student Team Championships. His score at Haifa in 1970 was the highlight of his career because he won the gold medal for best fourth board score with a 5.5-1.5 score. 
     In his later years, Verber, who was quite obese, was plagued by poor health and was confined to a wheelchair. 
     Verber's opponent in this game was Austrian FM Werner Mikenda (September 15, 1946-September 11, 2008, 76 years old) who was a chemist and an associate professor at the Institute for Organic Chemistry at the University of Vienna. His last chess activity seems to have been around 1985

Bxb7 Qxb7 {If you are bored, hang on...things are about to get exciting.} 21. e4 {This turns out not to be so good because it saddles white with a backward d-Pawn. Either 21.Na4 or 21.f4 would have kept up the boredom.} Bd4 22. Nc2 Nc6 23. f4 Nc8 24. e5 N8e7 {Positionally black stands well here because of white's backward d-Pawn and the fact that he can occupy d5.} 25. Ne4 { One suspects the N is headed for d6, but one would be wrong!} Bxa1 26. Nxc5 { Objectively this is not a very good move, but because he has a poor game positionally and a slow strategic battle is not likely to turn out well for him Verber decides on some tactical shenanigans.} (26.

Black has two Ns vs a R+2Ps but his position is judged to be better because of the activity of his pieces. In fact, in 5 Shootouts using Stockfish, black scored 5 wins.}) 28. Qe4 Nxc2 (28...

GM Andrew Soltis pointed out that black's two pieces are superior to white's R and so black definitely has winning chances. But, somehow Mikenda believed he had lost the exchange and when he resigned he told Verber, "I have no moves."} (33. Nxb6 Bxb6 34. Rxb6 N7d5 {In Shootouts black won 2 games while 3 were drawn.} (34... Rxa3 35. Rb8+ Nc8 36. Rxc8#)) 1-0
