+### Measurement
+Given the following scenario, where we have splitted red rook, white horse and white cannon.

+And the white player would like to make the move `e7e3` to capture the red horse. In this case we will make a [measurement](https://en.wikipedia.org/wiki/Measurement_in_quantum_mechanics) to check if there is exactly one `cannon platform` between the cannon and the target. Depennding on the measurement result, you should see one of the two scenarios (with equal probability):
