Brilliant move, and I've done the occasional brilliant move, is generally a move that wouldn't stand out in a crowd, yet ultimately is the dagger that starts a chain of moves that leads to your opponent's downfall.
A move that quickly, after a couple more moves, becomes apparent that the move was a game changer: suddenly a stale drawish game, or perhaps you were on the ropes, sucking wind just to not get mated or crushed, turns your game into win as long as you don't blunder or make a critical mistake.
Certainly a brilliant move by someone 1200 would not compare to a brilliancy be a player rated 1600 or 2200 or Magnus Carlsen. That's what nice about brilliant moves: they can scale according to what would be expected of a player at a particular rating level.
If a 1200 finds a brilliant move, its probably something a 1700 would find in a few seconds or less under time pressure.. 😉
I have played a lot of games and analyzed them but i think i could never played a brilliant move. Anyone did? Show me below.
