Blitz chess
Blitz chess is high-speed chess that allots only 5 minutes or so per side. The world championship in blitz chess allows only 3 minutes per side but 2 extra seconds per move. Blitz chess is faster than "rapid chess," which allows 10 minutes per side.
It is common for a player to win blitz chess when his opponent runs out of time (flagging). This happened to world champion Magnus Carlsen at the Sinquefield Cup in 2019 where blitz chess is used as a playoff if classical chess and rapid chess fail to produce a clear winner.
Blitz chess rewards quickness, and players who excel at blitz chess are not necessarily the same who prevail at the slower, classical chess. However, mastering classical chess is considered essential prior to excelling at blitz chess.

Overall strategy
Quick, conservative moves during the opening phase, while attempting to build an advantage in time or position, is a winning approach. Vigilance for blunders by the other side to gain an advantage in pieces, while carefully avoiding blunders of one's own, can help win in a majority of these games.
Placing the opponents queen in jeopardy with protected pieces, and likewise for the opponent's king (without the need for protecting the attacking piece), can help attain a time and positional advantage.
Common mistakes
Here are some common mistakes made in blitz chess:
- instinctively running from an attack and missing opportunities to capture the attacking piece, or counterattack; likewise, moving too quickly when attacked, rather than considering options
- failing to recognize a double threat created by an opponent's move, mistakenly focusing on only one of the two problems the move created.[1]
- failing to recognize the imminent possibility of checkmate by either side, particularly when an opponent's queen lurks in the vicinity of your king.
- failing to recognize hidden attacks.
- advancing your queen too early in the game.
- failing to notice what the most recent move by the opponent was.
- failing to see all the options available to an opponent's knight and yours.
- failing to recognize and use the long diagonal reach of bishops.
- failing to be watchful for an opponent's blunders, as when the opponent advances his queen.
- overreacting to one's own blunder in losing a piece - top players can win starting without even a queen.
If forked
If two of your pieces are placed in a fork by the other side, then an often-missed way to escape the predicament is to use one of the pieces to place your opponent in check.
Strategy based on time or relative position
At any point beyond the initial opening, you will be either ahead or behind on the clock, or ahead or behind in pieces. Each of those situations entails different strategy.
Ahead on time
When ahead on time in blitz chess, the strategy should become more defensive as the other side is required by the clock to take more chances. Protect your king and queen, and look for mistakes by the other side.
The emphasis if ahead on time should be to use the extra time to avoid blunders while capitalizing on blunders by the other side. The clock often decides the outcome in blitz chess.
If the other side then plays defensively then you'll win on the clock; if the other side aggressive attacks your defenses, then you can capture their pieces and gain an additional advantage.
Don't be afraid to exchange major or minor pieces when ahead on time. Better to exchange them in an even trade than have the other side capture them with aggressive play to catch up. Also, simplifying the material on the board means it is unlikely the other side can score a surprise checkmate.
Ahead on pieces
When ahead with major (queen or rook) or minor (knight or bishop) pieces, then in blitz chess it is advantageous to immediately force trades in other pieces with the other side. Their arsenal diminishes as does yours, but it becomes impossible for the other side to prevail.
Pawns are not considered "pieces" but if you have an edge of several pawns over the opponent, then a trading strategy should also be considered.
The bigger the advantage on pieces (such as capturing the other side's queen), the more aggressive the trading strategy should be.
Ahead on position
When ahead on position, then focus on attaining checkmate without being distracted by the opponent's clock. Managing enough time to checkmate the opponent becomes the priority. Your opponent is unlikely to recognize your positional advantage and may feel overconfident if it has an advantage on time or in pieces.
Behind on time
Hikaru Nakamura, considered the greatest speed chess player in history, recommends simplifying (exchanging pieces) when significantly behind on time:
| “ | When you are up a lot of material — or down big on time — it’s important to eliminate your opponent's pieces to simplify the position. If you have two rooks vs bishop and knight, sacrifice one rook for the knight. Simplifying allows fewer chances for checks, counterplay, or complications.[2] | ” |
Behind on pieces
Time Management
Managing the time effectively is perhaps the most important tactical consideration. Sizing up the board while the opponent thinks of his moves, and quickly assessing the threats that his pieces and movements present, is essential.
When a player is behind on the clock with less than 2 minutes to go, the best strategy is not to try to catch up on time, but to manage what time is left in order to achieve checkmate. Moving quickly when ahead on the board but behind on the clock is a mistake in blitz chess. Instead, ignore your opponent's clock and instead manage the time in pursuit of checkmate.
When down on the clock with less than 30 seconds remaining, look to advance pawns as a way to build time and position.
Spending less time on early moves and more time when one's king or queen is in jeopardy is helpful. When ahead on the clock, taking a bit more time to be careful is worthwhile. When behind on the clock, look for opportunities for capturing pieces which result from mistakes by the opponent as he moves too quickly.
Successful tactics
Placing your opponent in check quickly is an often successful approach to blitz chess. But if ahead on pieces near the end of the game, repeatedly putting the opponent in check can simply waste valuable time which could instead be used to develop a path to victory by checkmate.
Algorithm
Quick algorithms are helpful to manage time. When the other side moves, quickly review:
- does their move jeopardize, directly or indirectly, one's king or queen
- did they blunder in their move such that their piece can be captured
- can you move a piece out of jeopardy by placing the other side in check, or jeopardizing one of their pieces?
