Why My Chess Blunder?

Rewire your brain: Testing to offset forgetting

We all know that blunders, mistakes can be critical, they often make or break entire games. At MyChessBlunder, we believe that practing one's mistakes soon after they are made is the most efficient way to learn. This understanding is based on some of the best scientific research on brain plasticity, incorporating the concepts of repeating testing as a trigger for learning, or in the words of Dr. Andrew Huberman, "testing as a way to offset forgetting".


Testing soon after a blunder is made

We additionally incorporate the proven concept of testing soon after exposure to new material through our My Chess Blunder email alerts feature. Science suggests that the sooner you are able to review your blunder, the less likely you are to ever repeat it.

Beyond typical chess puzzles

We all enjoy solving chess puzzles, but My Chess Blunder strives to present you with the most relevant puzzles for you specifically based on analysis of your play, puzzles individually crafted to helping you improve your chess in the most efficient way possible.
