- There is a certain level uncertainty about where these pcs will land. Yes perhaps stockfish could try to add all possible future placements but I expect that would significantly hinder stockfish as the the number of possibilities grow hundreds of times.
Your opponent doesn’t know which piece will be where until you reveal it. Therefore can’t attack a non defended pawn on b column because you may reveal a castle on next turn.
On the overall it mitigates problems of weird openings in regular chess 960 but End game stays the same.
I built Hidden 960 Chess to bring back human creativity. At https://hidden960.onur.works, your back rank starts hidden—gray squares hide your pieces from a secret pool (1 King, 1 Queen, 2 Rooks, 2 Bishops, 2 Knights). You reveal them as you play, and if an opponent threatens a hidden square, it must be revealed immediately. When only a couple of hidden squares remain, you reveal them together. Currently rules aren't enforced and no computers.
Because of the hidden information and forced reveals, computer algorithms struggle with planning moves, making the game a true test of human intuition. Give it a try
lol. I was a going to build this. Even purchased the domain alert.now
I even have news based version active implementation at alarms.global if you install it to your phone as PWA you get push notifications when something important happens in your region or can notify you before public holidays
