Being a deep, sophisticated, profound type, my favourite form of chess is undoubtedly blitz. And during any game at a time limit over about 15 minutes for all the moves, I will regularly suffer bouts of boredom and distraction. It seems it's not the same for all chess players, though. The excellent, albeit occasional chess blogger Rocky Rook puts it like this:
Do you ever find yourself in the middle of a game and notice that your heart is racing and your palms are sweaty? It happens to me every now and then ... especially in games that are really important to me.
I've noticed that the last couple of games I've played, that when I spot a tactic, my heart rate jumps up considerably. I find myself having to control my breathing.
Rocky Rook also uncovered this piece of medical research (PDF file), entitled: Hopelessness Is Associated With Decreased Heart Rate Variability During Championship Chess Games. The title was pretty much all I understood of it, but the message basically seems to be if you find yourself heading toward a coma during a game, you're going to lose. But if you think you're at risk of a heart attack, you're going to win. Mild palpitations predict a draw.
So how is it for you?
