Cx(10,9)!?
Chess on an Infinite Plane (HorribleTomato - captaintugwash)


I'm just bulding a board for analysis, I'll get back to you in a minute on whether I think this is even, or if I have a serious attack. I assume you covered the mate in one threat, I haven't even looked what square your queen moved to.

I think you mean Q(1,4), since it's legal and defends the immediate threat. Assuming that move, this is a visual aid, but the coordinates will be no help...
Also, sorry it's wider than needs be, if I resize it now I lose it all so deal with it.

I don't think there's any way you can defend both the mate in one threat and this one. I wish I could say I saw this earlier, but I didn't, I was too busy defending.
This is surely running out of steam...
51... R(10,9)
