Is it possible to setup a chess board where every square on the board is only controlled once. Occupying a square does not mean controlling it.

If it is possible, with how little pieces?

Piece Cost:

  • Pawn: 1

  • Bishop: 3

  • Knight: 3

  • Rook: 5

  • Queen: 9

You are not allowed to use the king.

I found it very hard to only control each square once. Any attempt at limiting the physical number of pieces was turning into an issue. I suspect this can be beaten, but I can manage the whole board in 32 pawns. At least they're only 1 point each.

32.

32 Points

  • $\begingroup$ @skv would it have mattered if they were all white? Each square would still only be controlled once. $\endgroup$

  • $\begingroup$ @Joel Great work! I wonder if it's possible without it all being 32 pawns... Can 32 be beaten? $\endgroup$
