Technically, blitz is 3 minutes a side or longer. What they're describing is actually next level fast. The chess they're talking about is called bullet. All serious chess needs to be played with time limits, and, to me, chess has always been the best corollary for football. I'm a huge football fan and a fairly serious chess player and have always called football the chess of sports. The whole he-goes-there-I-go-here-and-if-he-goes-there-next part is a lot like calling plays, changing defenses, adjusting formations and so on. I love this, and I think there is great value in teaching bullet chess. Way to go. And I would love to see JA try this.
