Tactics for beginners: the fork, the pin, the double attack

Alexey Mudry
The overwhelming majority of amateur games are decided not by strategy but by one move somebody failed to see. We go through six motifs that cover almost all tactics at beginner level, and a way to learn to see them. The rules of the pieces are in the article on rules of chess.

What tactics are and why they matter more than anything else

Tactics are a short forcing sequence of moves that wins material or gives mate. Unlike strategy, they can be calculated exactly: either the motif is there or it is not.

For a beginner this is the main subject, and here is why. Up to a certain level, games end not because somebody placed their pieces better but because somebody hung their queen. Studying opening subtleties while dropping a piece every ten moves is time wasted.

The one-question rule

After every move your opponent makes, ask yourself one question: “what is he threatening to do now”. That question alone removes more than half of all blunders.

The fork

One piece attacks two or more at the same time. The opponent saves one, you take the other.

  • The knight. The great specialist: its L-shaped move is hard to spot, and a fork on the king and queen wins the game on the spot.
  • The pawn. The most galling one: a pawn attacks two pieces at once and both are worth more than it is.
  • The queen. Often attacks the king and an undefended piece at the other end of the board.
  • The rook. Catches two pieces on the same rank or file.

How to spot them: look at your own pieces standing on squares of the same colour a knight's move apart, and at any two pieces on the same line. Check separately the squares your opponent's knight can jump to with check.

White to move: Ng6+ - check to the king on f8 and an attack on the rook on h8 at the same time. The king steps away, the knight takes the rook.

The pin

A piece cannot move because something more valuable stands behind it. This works only for long-range pieces: the queen, the rook and the bishop.

An absolute pin
the king stands behind the piece: it may not move at all, the move is simply illegal
A relative pin
a queen or a rook stands behind the piece: it may move, but at a cost

A pinned piece effectively stops defending anything - that is the most important consequence. The classic motif: pin the defender and attack what it was defending a second time.

What to do if you are the one being pinned: do not panic and do not start trading everything off. Usually it helps to move the king or the queen off the line, bring another defender to the pinned piece, or trade off the piece doing the pinning.

The bishop on g5 pins the knight on f6 against the queen on d8. Moving the knight is technically legal, but then the queen is left en prise - that is a pin, not a prohibition.

The double attack and the discovered attack

Two related motifs that beginners often confuse with each other and with the fork.

  • The double attack. A broad term: any simultaneous threat against two targets. The fork is a special case of it, but the threats can also be of different kinds: an attack on a piece plus a mate threat, for instance.
  • The discovered attack. You move one piece away and open a line for another standing behind it. Two moves work at once instead of one.
  • The discovered check. The same motif, where what is opened is a check to the king. The piece that moves away can do whatever it likes - nobody will take it, because the king has to be saved.
  • The double check. The strongest version: both pieces give check at once, and the only reply is a king move. No block and no capture will help.

The double check is worth remembering separately: it is what the most beautiful mating combinations are built on, including the smothered mate.

Deflection and decoy

Motifs for making an opponent's piece end up somewhere they do not want it.

  • Deflection. A piece is defending something - you give it a more urgent job. The classic: a check with the queen after which the defender is forced to move away and the square it was guarding is left empty.
  • Decoy. The reverse: you force a piece onto a particular square where a fork or a mate is waiting for it. Usually with a sacrifice that cannot be declined.
  • Removing the defender. The straightforward version: simply trade off the piece holding the defence together, even at the cost of the exchange.
  • Overloading. One piece is defending two things at once - which means it is defending neither. You take the first, and the second is left undefended.

What all four have in common: look for your opponent's defended pieces and ask exactly who is defending them. Tactics most often start with the answer to that question.

Why beginners lose pieces

They look only at their own plan
and do not check what the opponent is up to
They do not see long-range pieces
a bishop from the far corner of the board is invisible to a beginner's eye
They forget about the knight
the L-shape does not read intuitively, unlike straight lines
They move fast
most blunders are made in the seconds before the clock is pressed
They do not check the checks
an opponent's check opens up half of all tactics
They think a piece is defended
when the defender is pinned, overloaded or itself under attack

A working habit before every move: check all the checks, all the captures and all the attacks - your own first, then the opponent's replies. It takes about twenty seconds and saves you a piece a game.

How to train tactics

  • Solve a few puzzles every day. Fifteen minutes daily does more than two hours once a week: a motif should be recognised, not computed.
  • Solve them in your head, without moving the pieces. Otherwise what you train is shuffling pieces by hand rather than calculating lines.
  • Go through your mistakes. A puzzle you missed has to be understood to the end, not scrolled past.
  • Start with mating patterns. Ready-made mating patterns are the fastest progress at the start: a catalogue of positions and trainers.
  • Check your own games. After a tournament, run through your games and see exactly where the tactics were - on analysing your games.

And above all - play. Tactics spotted in a puzzle and tactics spotted at the board with the clock ticking are different skills. The second one is trained only by tournaments - a tournament for beginners.

Try your tactics at the board

Working through puzzles is useful, but a motif sticks when you have managed to play it in a live game. The next evenings for beginners are in the Vibe Chess app, and questions go to Telegram.

Common questions about tactics

What is a fork in chess?

One piece attacking two or more at the same time. The opponent can only save one of them. A fork is most often made by a knight or a pawn, but any piece can make one, the king included.

How is a pin different from a fork?

A fork is an attack on two pieces at once. A pin is a situation where a piece cannot move because something more valuable stands behind it. Only long-range pieces pin: the queen, the rook and the bishop.

What is a double check and why is it dangerous?

A check given by two pieces at once: one moves off a line and opens a check from another, while attacking the king itself. You cannot block it or capture the attacker - a king move is compulsory.

How do I stop blundering pieces?

Before every move, check all the checks, captures and attacks - your own first, then the opponent's possible replies. And after every move your opponent makes, ask “what is he threatening with that”. It takes about twenty seconds and removes most blunders.

How many puzzles a day should I solve?

Fifteen minutes every day beats two hours once a week: the goal is for a motif to be recognised instantly, and that comes from regularity. Solve them in your head without moving the pieces, and always go through your mistakes.

A tournament without a paper crosstable

Everything people usually keep in a spreadsheet is already in the app: pairings, points, tie-breaks, round order. Free, with no subscriptions and no cap on the number of players.

  • Swiss
    many players, one evening: four or five rounds are enough
  • Round robin
    the fairest format for six to ten players
  • Free meetup
    not a tournament, just an evening of chess - who is free and who is playing is visible in the app

More than a bot: the app, FIDE rules and a TRF report

  • The app. Besides the bot there is an app - inside Telegram and simply at playvibechess.com/app: what is on in your city, the player list, a live table, the current round, your profile and game history - everything that is awkward to read as chat messages.
  • Pairings by FIDE rules. Pairings are computed by bbpPairings, an open-source engine implementing the Dutch system: score groups, floats on an odd field, colour alternation, no rematches, and no player gets a bye twice.
  • A TRF report. A finished tournament exports as a single file in the FIDE data exchange format - the one arbiter software and federations accept. Your profile stores the FIDE ID, national federation code, title, sex and date of birth for it.
  • Free. All of the above, with no subscriptions, paid plans or limits on the number of tournaments and players.

At the board since childhood: hazy about his rating, precise about every rook he has blundered. Counts an evening as a good one if the opponent stayed to talk afterwards instead of rushing off to check with an engine. Message →
