I made a free tool called ChessGrammar that finds tactical patterns in chess positions.
Paste any FEN or a full PGN and it detects forks, pins, skewers, discovered attacks, back rank mates, and more (10 patterns total).
Search for "ChessGrammar" to try the playground — no signup needed.
It also works on full games: paste a PGN and it shows every tactic that was played or could have been played.
Would love feedback from the community!
I must say it looks nice, good work here.
I think it's fair in what it detects.
