His Youtube channel has some great insights on different learning strategies.The Najdorf variation of the Sicilian Defense chess opening being large to learn, on this page of you can download a special PGN file on the Najdorf variation of the Sicilian Defense. It's from a Stanford Phd who specialises in learning and cognition. Here's a video explaining the difference. Learning research is conclusive that mixing themes (interleaving) is a better, more efficient way to learn. The first type is called interleaving, the second is called block practice. As Nate says, mixed-theme exercises are better than a lot of exercises on the same theme. That way, you can build up a bank of puzzles you didn't solve the first time and which need reviewing.ģ. (Lichess doesn't have this feature.) The individual pgns of each wrong puzzle can then be merged into a composite pgn. I use Chess Tempo mostly, because after each puzzle you can download the pgn for it. Isolate and review any tactics puzzles you got wrong. Many people focus on a tactic they want to inflict on an opponent, but it's equally important to see a tactic that's about to be unleashed against you! Defensive tactical vision is a critical skill.Ģ. After doing an exercise, whether 2D or 3D, flip the board and do it again to see how it looks from the other side. Lots of good advice in this post from Nate. If you are consistently getting less than 70% correct, move to an easier source, and return to the harder source when your skills improve. If you work with sources that are over your head, you’ll spin your wheels and become discouraged. Unfortunately, it doesn’t work like this. The logic, I suppose, is that if you could improve by working with a source at your level, you could improve even more with an even harder source. I find that many of the highly motivated chess players who read this newsletter work with sources that are too hard for them. Likewise, 70% correct is a good balance, where the exercises are challenging and pushing your limits, but not so hard that you simply can’t understand the solution. 5-10 minutes is a solid amount of time to think, but you don’t want to go much over that, because using more than 10 minutes for a single move would rarely be good time management in a real game. There is also value in doing “fast” tactics, but those I prefer to just solve from a screen or diagram – otherwise setting up the position takes too much of the study time. The reason for the 5-10 minutes guideline is with this type of training you’re looking for positions that force you to go beyond your initial intuition and use a structured thought process. I agree with FM Peter Giannatos (as quoted in Ben Johnson’s new book!***) that you should focus on exercises that take around 5-10 minutes each, and where you can solve about 70% correctly.
