FRITZ 20 and the Lesson of Individualized Training from Chessboard to Pitch

In a small Moscow apartment, amid stacks of match recordings piled as high as the desk, I switch on FRITZ 20 every evening. What keeps a 69-year-old like me sitting there is not a beautiful move, but the way this engine forces the user to find the mistake instead of handing over the answer. People watch players run. I watch the whole block shift. On the chessboard it is the same: the point is not the move, but how a training tool reshapes the user's thinking. A piece of software, after all, is a tactical system in miniature. FRITZ 20 positions itself in three short lines: your personal chess trainer, your toughest opponent, your strongest ally. That positioning deserves a pause, because it does not promise victory, it promises process. The product targets two groups. The first is people taking their first steps into serious chess training. The second is those already playing at tournament level. The gap between them, measured by training needs, is far wider than the gap in rating. A beginner and a tournament player may sit at the same board, but they need two different syllabi. I have followed chess and football side by side for 53 years, and what I learned is that both are misunderstood in the same way. Spectators love results. Coaches must live with process. A strong chess engine does not automatically make its user stronger. A correct drill does. This is the point most sports tools skip: computing power is not the same as coaching quality. That is why I read carefully the three adjectives FRITZ 20 uses for itself: more efficient, more intelligent, more individualized. All three belong to method, not to computing power. A tool can calculate tens of millions of moves per second, but if it does not help the user understand why one move beats another, it is just a machine. Start with the word individualized. In sports training generally and chess specifically, the most common mistake is imposing one shared curriculum on everyone. A player weak in the endgame needs endgame work. A player weak in the opening needs opening work. The same curriculum for both produces two different kinds of waste. FRITZ 20 claims to move the other way: adjusting drills to each individual. Next comes efficiency. Efficiency in training is not doing more, it is doing the right thing at the point of pain. Patience is not standing still. Patience is waiting for the right pressing rhythm of the opponent. On the chessboard, that rhythm sits at the moment the opponent loses good structural balance. A good training tool must point to that moment, not merely to the best move. And finally, intelligence. Intelligence here, as I understand it, is the ability to ask the right question. A system does not lie, but it can only be heard when the data is thick enough. An engine that issues an evaluation without explaining the reason teaches its user very little. The real value of FRITZ 20 lies in being opponent, teacher and training partner at once. One detail about FRITZ 20 catches my eye: it is designed for both beginners and professionals. That is a hard bet. Serving two levels with one product easily ends up pleasing both only moderately. The solution lies in individualization: one engine, two training modes. My experience of watching matches has taught me that a good tool does not say more, it says the right thing. My experience of watching matches shows a recurring rule. When two opponents are level, the winner is usually not the faster calculator but the one who asks the right question first. This holds in chess and in football. A defender who reads the opponent's intent half a second early blocks a ball a slower player never touches. FRITZ 20, if it does what it claims, will teach its user to read that half second earlier. In 2026, when football stopped for seven months, I used that time to compile data on hundreds of matches. Seven months without football, seven months of asking why. The lesson I drew was not in the numbers but in how to frame questions. With the same data, a good questioner sees structure, a poor questioner sees only scores. A training tool is the same: it is only as good as the question the user brings. Seen from the sideline, there is one thing rarely mentioned. Every strong engine creates a subtle trap: users gradually trust the machine's evaluation more than their own judgment. I have seen this in chess. I have also seen it in football, where young analysts stare at data tables and forget to look at where the defensive line stands. Data becomes a crutch, no longer a tool. A good chess coach, like a good football coach, does not produce dependent players. They produce players who ask their own questions. FRITZ 20, at its deepest layer, only succeeds if over time the user needs it less, not more. That is the paradox of every good training tool. I still remember a piece of mine being savaged years ago. Data never takes offense. I spent six weeks reviewing every recording and published a correction with figures. That lesson applies directly to how I read a new tool: do not trust the pitch, verify through process. For me, FRITZ 20 is worth watching not because it is stronger than the previous version, but because it bets on a correct idea: training is a relationship between person and tool, not a contest between person and machine. I am sixty-nine. I still learn from the young. Football never retires, and neither does chess.
