I developed an online version of Hand and Brain Chess to play against a computer. In each move the BRAIN (stockfish engine) will highlight the piece or pieces that are the best move and are the only pieces that you can move. It is your job as the HAND to play the correct move.
At first I thought this was stupid, but after giving it a try it's addicting. It's great to get instant feedback on a move you aren't sure about.
Edit: Is there a variant of this without limit the piece you can move? Basically I just want the instant feedback without getting told which piece to move.
Can someone explain to me why this was called an "excellent move"? https://imgur.com/a/Fyg4PuW I eliminated a night but I feel like the pawn could eliminate my bishop easily. See also the second picture for another (to me) inexplicable situation.
In the first position that pawn can´t take the bishop because then you can move your rook attacking their queen and she is pinned (can´t move because is aligned with the king). The second position you can move the rook, attack the queen, and he must take it. The common value of the pieces are pawn:1, bishop,knight3, rook:5, queen:9 so winning a quen for a rook is an excellent trade.
You can use lichess.com to analyse the moves. Here is the position if you want to take a look https://lichess.org/analysis/standard/r3k2r/pb1pqppp/1ppb4/4...
Also You can copy & paste the generated moves of the game (like 1. e4 d5 2. exd5 c6 )to the pgn text area.
Really cool! But it doesn't seem to be deterministic. I played a "perfect move", took it back, played it again, and it was downgraded to something less than perfect. Also, I took a different move back and was presented different pieces to move. Maybe the engine, given a chance to run longer, updates the list of best moves?
That's interesting, probably a bug in the take back function. There are multiple engine evaluations running in the background at the same time, current evaluation, opponent evaluation and the brain evaluation, so it could be possible that when you take back there is some problem with synchronization

In the original variation 2 players plays together against someone, one say the piece name to move (BRAIN) and the other must move it (HAND). There are some really funny videos online https://www.youtube.com/watch?v=TL2pn1yIs2Y https://www.youtube.com/watch?v=N-fSQAX4wkg
