How to calculate in chess: a method, and two ways to train it

Calculating is not seeing ten moves ahead. It is looking at the right few moves, in the right order, and checking what your opponent can do back. Here is a simple method for it, and the two trainers in Chess Coach that turn it into a habit.

A calculation exercise in Chess Coach: four numbered candidate moves drawn as arrows on the board

A method for every move that matters

  1. Read the position first. Who is better, and what does your opponent threaten? Many club blunders come from never asking that question.
  2. List your candidate moves. Checks, captures and threats first, because they force the reply and are easier to calculate. Then one or two quiet moves that fit the plan.
  3. Calculate each one to a quiet position. Follow the forcing line until nothing is left to take or check, and judge the position there, not halfway.
  4. Look for your opponent’s best reply. Before you play, ask what the strongest answer to your move is. If it hurts, go back to the list.

Train it with decisions

The Decision Trainer in Chess Coach walks you through those steps on real positions. Before you move, it can ask who is better, what your opponent threatens or what the plan is. Then you choose your move, and often you also play how your opponent will reply. If your move allows something strong, you have to find it yourself. There are 149 exercises, grouped by theme.

Train it with repetition

The other half of calculation is not needing to calculate: seeing the pattern at a glance. That is what the Woodpecker method trains: the same set of positions, again and again, faster each cycle. In Chess Coach each position shows four candidate moves as arrows; you pick the best one and then play the line that follows.

What is free

Five decision exercises are free, and so are the first ten positions of each Woodpecker set. The rest of the Calculation Lab is part of Premium.

Questions

How can I get better at calculation in chess?
Use a fixed method on every important move (candidates first, forcing moves first, check the opponent’s best reply), and train on positions where you have to commit to a move before you see the answer.
How many moves ahead should I calculate?
As many as it takes to reach a quiet position, and no more. In forcing lines that can be many moves; in quiet positions, judging the position well matters more than depth.
What are candidate moves?
The short list of moves worth calculating in a position. Choosing them well, and checking forcing moves first, saves you from calculating the wrong things.
