Blitz Chess
"While taking a break from work, I went online to play a couple of blitz games in preparation for tonight's event. I lost the first, badly. The second was worse. After three losses in a row, I knew I was in trouble.
That's how the addiction works: losses mean more play. The game plays second fiddle to the struggle for rating, for pride, for something."

Quoted in Robert Desjarlais, Counterplay: An Anthropologist at the Chessboard (2011)
In a game G/30 which turned into a blitz game I played last Week at Windward Chess Club with only seconds left yes two knights worked nicely, but had I not promoted a pawn to knight instead of Queen that forked the King a nearby Rook and thus alowing a checkmate as the other knight was within range to prevent King running towards the center and running out the clock. But had position been slightly different a lost on time may have occurred instead of win by checkmate via a Queen and promoted Knight on black's back rank. :-)

In blitz, the knight is stronger than the bishop. - Vlastmil Hort
Playing rapid chess, one can lose the habit of concentrating for several hours in serious chess. That is why, if a player has big aims, he should limit his rapidplay in favour of serious chess. - Vladimir Kramnik
Like dogs who sniff each other when meeting, chess players have a ritual at first acquaintance: they sit down to play speed chess. - Anatoly Karpov
Yes, I have played a blitz game once. It was on a train, in 1929. - Mikhail Botvinnik
He who analyses blitz is stupid. - Rashid Nezhmetdinov
It is very difficult to play a single blitz game! You want to play for a long time. So I tend not to do that anymore. - Viswanathan Anand
Blitz chess kills your ideas. - Bobby Fischer
