Ofir Press(@OfirPress):My brother developed a method that allows LMs to explain why one chess move is better than another. The LM does this by writing code that analyzes the board, the LM knows how to write this code since it gets access to 200k board states from real games along with engine analysis.

LMs can play chess, but they can't really explain their moves well (chess engines can't at all). Our new BinProp scaffold tackles this, and nearly triples LMs’ score on our chess-explanation benchmark. It works on other games too! Try it on your own games on our site-🧵👇
