Can someone explain why moving the rook D1 is a brilliant?

It was the 29th move for black and after the game found out it was from analyse got a first brilliant move. Thought it was due to the end game where a queen sac caused unstoppable promotion but it was actually a bishop sacrifice by moving the rook. Don't know why it was deemed a good move and seemed like didn't blunder during the brilliant but wanted to know what special moves the evaluation bar wanted after the brilliant. https://www.chess.com/analysis/game/live/141294672834/review?move=57&move=57&tab=review&classification=brilliant&autorun=true

It won black alot of pawns, but the analysis didn’t give why it was sooo good.

Apparently, you would have been able to win 3 pawns for the bishop, and since you temporarily sacrificed a bishop, it was called brilliant.

The truth is that computers can't actually tell what's hard to find for a human, thus cannot tell what's 'brilliant'. The definiton now is that a "Briliant" move is important to the game, the top engine move and involves a sacrifice, hard to find or not.

Like Game Review's rating estimate, they're just for fun... there's nothing wrong with that as long as you don't take it too seriously.

More importantly you should be asking why you missed 33...Qg3+

The best part is the period between move 6 and 10, when both sides ignore the free knight and every move is a horrible blunder.

yep, 2000 is terrible... we're all complete trash at chess compared to our 3888 Stockfish overlord. 😆

jenny mod characters The rook move might be marked brilliant because it sets up a deeper tactic, like the bishop sacrifice you mentioned, which engines recognize as key to winning.

You're looking for what you'd call "brilliant", but computers can't tell since it can't be something easy to find, almost by definition, and they don't think like we do. They tried early on to look at moves that weren't the top choice before a certain depth of analysis but that turned up too many odd results, so they changed the definition. A "brilliant" move now can be any move that involves a sacrifice, even an obvious one, if it's the "best" move and important to the game.

chess.com, 2022:

"We replaced the old Brilliant algorithm with a simpler definition: a Brilliant move is when you find a good piece sacrifice. There are additional conditions: You should not be in a bad position after a Brilliant move. You should not be completely winning even if you hadn't found the move. We are also more generous in defining a piece sacrifice for newer players compared to those who are higher-rated."

The thing you're answering to is a spam message made by a commercial spambot. The first 3 words are a link, the rest of the post is a generic AI-generated nonsense. It's hard to not notice it.

Big deal, genius. There are more than the three of us here and misunderstanding, about "brilliant moves", is common.

But there's no misunderstanding here, it's just a spambot spamming nonsense. It should be reported and deleted.
