Parker insisted on playing a game of chess before school started. The pieces were all mumbo-jumbo in a bag all mixed together: blue, red, green, gold, orange, black, purple, pink, etc. As we were setting them up, Parker got the idea to play with both the same color. Black on black. So we did. He didn't win, but he was able to play the game out. He only asked a couple of times which pieces were his. Otherwise, he was able to keep most of it straight in his head. It was 20 - 25 move game too. Brilliant kid.
