Thank you for your comment, I've fixed itp3, "cheekmate" -> "checkmate". I guess you had the next page's cheek pinching scene on your mind.
p4, "stalematess" -> "stalemates". Stalematess sounds like an insult for a girl who always ties.
Anyway, unhinged analogies are apparently expected from high level chess players, so the music rant is in line with that.
