Usually, in a zugzwang, the idea is to limit the number of moves that the opponent can make so that they will have to make a bad move. But what if we decided to give them lots of freedom, given that no matter what they do, they lose?
Thus an idea came to my mind for a construction task: What is the highest possible number of moves by the losing side in a zugzwang position?
Without prompted pieces, and counting different promotions as different pieces, I found a total of 73 in the following position.
[FEN "6K1/PB2q3/2p1p1k1/1NNPB3/6P1/1p4p1/1QPPPP1P/R6R w KQkq - 0 1"]
Yes, this is actually a zugzwang position for White. No matter what defense they employ, there are simply too many mating threats by the Black queen to handle. It's a mate in three at most according to Stockfish.
Is better possible for without promoted pieces? What about with promoted pieces?
I don't mind if you give an already known position-I highly encourage it in fact!
And have fun and good luck if you are making a new position on your own!
