List of Crazyhouse engines I want to get a list of all (because they are certainly only a few existing) crazyhouse engines. I searched in lichess forum posts by googling "crazyhouse engine" and collected many names and links from 3 different posts.

Initial list, to complete:

Sunsetter

Stockfish (a well known engine, recently implemented for crazyhouse, seems to be the strongest for this variant in this thread, is the default used in lichess for crazyhouse, important news: has beaten jann lee consistently in informal match in this playlist)

Sjeng

Tjchess

Immortal

nebiyu

pulsar

sjaak
