Using these libraries will help us focus only on the most interesting task: creating the algorithm that finds the best move.

We’ll start by creating a function that just returns a random move from all of the possible moves:

Although this algorithm isn’t a very solid chess player, it’s a good starting point, as we can actually play against it:

Now let’s try to understand which side is stronger in a certain position. The simplest way to achieve this is to count the relative strength of the pieces on the board using the following table:

With the evaluation function, we’re able to create an algorithm that chooses the move that gives the highest evaluation:
