Wednesday night. Nine moves. Fried Liver. Six seconds. Checkmate. 100%.
Is it possible to get 100% accuracy in a game?

Only if you are using stockfish or another AI that is built to do the best moves.
Or, if you have ever studied chess.

I played a 100% game
I’ve played all but the last move quite a few times. 4…Qc6 is a horrid move.

It's both 100% for both players if you play the Blackburne Shilling Gambit with the smothered checkmate- they're all book moves

I got 100% accuracy with both players 7 or 8 moves so yes it is: mikecala versus zenlover911 - https://www.chess.com/live/game/72294724107

Officially a lame thread I get 100s and 90+ all the time and I only know about 2 or 3 moves theory on maybe 2 books

All Book/Excellent/Best/Great/Brilliant.
99% though, in 16 moves.
yes, if the game stops after few moves.
