How to control the whole board with 8 standard pieces (one king, one queen, two rooks, two knights, two bishops)?
P.S. A piece doesn't control a cell simply by staying on it, so another piece must control it.

It's a studied problem: Oxford journal page
The three possible solutions are listed at the top of page 4.
Also noteworthy: there is no option with the bishops on opposing colors.
