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:
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)
