  While transformers have gained the reputation as the "Swiss army knife of
AI", no one has challenged them to master the game of chess, one of the
classical AI benchmarks. Simply using vision transformers (ViTs) within
AlphaZero does not master the game of chess, mainly because ViTs are too slow.
Even making them more efficient using a combination of MobileNet and NextViT
does not beat what actually matters: a simple change of the input
representation and value loss, resulting in a greater boost of up to 180 Elo
points over AlphaZero.
