Blitz chess
Blitz chess is a fast format where each player has about three to ten minutes for the whole game, so decisions rely heavily on pattern recognition and quick tactics.
Also called: blitz
In blitz, the clock is a constant pressure. A typical game gives each side three to five minutes, often with a small increment such as 3+2 or 5+3. You cannot calculate deeply, so you rely on what you have already learned: opening patterns, tactical motifs and basic endgames.
Blitz is excellent for building familiarity. You see many positions in a short time and learn which structures and tactics come up again and again. It also trains you to stay calm when time is short. The risk is that fast games can reinforce careless habits, such as moving without checking what the opponent threatens.
A balanced approach works best. Play some blitz for enjoyment and pattern practice, but keep most of your improvement time for slower games and study. Always look at your opponent's last move before you reply, and take a moment when something forcing is happening. Ratings in blitz are kept separately from other formats, so a number there does not predict your classical strength exactly.
It sits close to Hyperbullet. Hyperbullet is an extremely fast online format with only a few seconds, often fifteen or thirty, for the whole game, where reflexes and premoves matter more than thought.
It sits close to Time odds. Time odds is a handicap in which one player is given less time on the clock than the other, so a stronger player can face a weaker one in a more balanced game.
Also worth reading is Bughouse. Bughouse is a four-player chess variant on two linked boards, where each capture hands the taken piece to your partner, who may later place it on their own board instead of making a move.
