in puzzles it always shows white to move, but some puzzles need black to move first how to change that?
Randomly stops working after like 10 minutes.
overall works really well, but sometimes it just freezes forever until another move is made. it'll start working again if i go back a move, but when i go forward again it just freezes. no matter how many moves i go back, no matter how many times i refresh, it just can't find it in itself to...just work. if you could find this bug and fix it i (WE ALL) would appreciate it :) thanks!
work so bad, think what not my roock is mine actualy
Works for lichess puzzles as well. Directly suggests the best lines, shows arrows. Just need to reload the website sometimes, and might be a little slow. and press arrow keys to go to the previous move so that it works well again but, over all very good. Better ChessVision AI which requires you to press scan button and turn on stockfish for everymove.
Love this tool. Full Stockfish analysis directly in the browser, no server, no login, no tracking. Fast and clean UI.
