Calculation and Evaluation in chess

Often during a chess game, you have so many different choices of moves in a position (especially, in a middlegame position) and each of them might seem reasonable. The important part is that we need to calculate the attacking possibilities very precisely.

Most players would spend about 20-30 minutes in the process of making a decision in that ‘critical position’ and unfortunately, that player would eventually play a bad move or make a terrible blunder. Have you been there?

Let’s take a look at a practical example.

White to move

Black just played 23…Qc8 and it is White’s turn now. How would you evaluate this position? Well, White is two pawns up; one of them is doubled on the c-file, while Black has a Bishop pair for White’s Knight pair.

How would you play here as White? You may also record your calculations/variations for your convenience. Please, take a few minutes and consider this training as a serious one. After calculating all possible variations, continue reading.

The above position is from the game of our guest coach IM David Miedema. As I have already mentioned in the beginning of the article, he took a lot of time in this position, and ended up making a blunder. But what was your evaluation and calculations? I hope you did not make the same blunder. ?

You’re welcome to see what happened in the game and check your calculations by watching the video lesson below:
