Anyone who's interested to see how brilliant AlphaZero played against the best chess computer (then), with solid explanations: [VIDEO]
A great example I love showing people is Alpha Zero's infamous "Immortal Zugzwang Game" against Stockfish [0]. Stockfish gets utterly annihilated in a trap that seemingly springs out of nowhere, though of course the reality is that Alpha Zero was actually really in control the entire time. [0] [VIDEO]
Here’s a chess stackexchange of positions that stump engines [LINK] It basically comes down to “ideas that are rare enough that they were never programmed into a chess engine”. Blockades or positions where no progress is possible are a common theme. Engines will often keep tree searching where a human sees an obvious repeating pattern. Here’s also an example where 2 engines are playing, and deep mind finds a move that I think would be obvious to most grandmasters, yet stockfish misses it [VIDEO] That being said, I’m not sure that this necessarily correlates with brilliancy. There are a few of these that I would probably get in classical time and I’m not a particularly brilliant player.
