My thought process was, let me try out a few moves that attack Black. There aren't that many, so... Kb8? No, not allowed. Kb7? No, not allowed. Pa7? No, that doesn't really help. Ra7? No, that doesn't lead to anything useful. Ra6? Oh, yeah, that works.

But I wasn't thinking in text, I was thinking graphically. I was visualizing the board. It's not beyond the realm of possibility that you can tokenize graphics. When is that coming?
