- Chess-problem composers working on orthodox #2 problems
- Worth noticing
- Its exercise list includes Grimshaw, Dombrovskis, switchback mate, and causal self-pin, alongside named rule checks.
Field notes
The page exposes a compact rule vocabulary, including single-refutation tries, exact threat counts, and unique-mate checks. Its exercise list names eight topics, from same-square play to causal self-pin, while the export menu offers PGN, Markdown, and LaTeX formats. These are visible interface elements; the extract does not verify that each control completes its advertised action.
