ThreeSadPandas Keeps a Chess Notebook of Its Own Mistakes

threesadpandas.com Observed source
Editorial interest 78/100 Selection signal · not a rating of the site

A public chess improvement blog collecting games, blunders, book notes, tools, and lessons from the board.

Landing page captured for the 2026-08-28 issue.

Field notes

The notebook separates played games, recent posts, guides, and book notes, with RSS and a linked Lichess identity providing paths beyond the homepage. Its examples mix personal failures with canonical chess material: one entry examines a Four Knights game using Stockfish 18, while another revisits Paul Morphy’s Opera Game. The author also describes a four-step blunder-check system that failed to prevent a rook blunder, giving the improvement project a concrete and self-deprecating subject.
