Okay, I dont know if you have tested that kata, but doesnt even works as intended, has a lot of complains, and its super old. I think this kata deserves to replace that one.

I dont know Why I seen the random test cases not well formated, idk if is there something I misunderstood or the tests dont work

[
  [
    ' ', ' ', ' ',
    ' ', ' ', ' ',
    ' ', ' '
  ],
  [
    ' ', ' ', ' ',
    '♔', ' ', ' ',
    ' ', ' '
  ],
  [
    ' ', ' ', ' ',
    ' ', ' ', ' ',
    ' ', ' '
  ],
  [ ' ', ' ', ' ', ' ', ' ', [ '♛', '♜', '♝', '♞', '♟' ], ' ', ' ' ],
  [
    ' ', ' ', ' ',
    ' ', ' ', ' ',
    ' ', ' '
  ],
  [ ' ', [ '♛', '♜', '♝', '♞', '♟' ], ' ', ' ', ' ', ' ', ' ', ' ' ],
  [
    ' ', ' ', ' ',
    ' ', ' ', ' ',
    ' ', ' '
  ],
  [
    ' ', ' ', ' ',
    ' ', ' ', ' ',
    ' ', ' '
  ]
]

Sometimes, it has arrays into the arrays, like, 3 dimensional instead of two, Idk if this a Kata problem or what

I would expect something like

[
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', '♟', ' ', ' ', ' ', ' '],
			[' ', ' ', '♔', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ']
	]

but instead is something like

[
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', [' ', ' ', '♟'], ' ', ' ', ' ', ' '],
			[' ', ' ', '♔', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '],
			[' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ']
	]
