Vladimir Nabokov's third novel "The Defense", involves which activity?

SQinfoNUTS, well don't know about books on chess but I find your comments always hard to swallow.

just watched the Netflix series, the queens gambit. It's a drama about a women's lifelong love of playing chess.

can always imagine a defensive art in Singing and cooking, with those high notes and the defence of the wooden spoon.... HOWZAT!!
