I am talking about move 38

It goes from -90 to 0

# Why it goes from 99 to 0 with the recommended move

If you play Bx24 on move 38, the position becomes the same as it was on move 34.

The only difference is that you has an extra pawn.

In other words, playing Bx24 on move 38 clearly improves the position compared to the one on move 34.

At this point, the AI stops calculating and says -99.0.

My problem was it did go from 99 to zero in the analyis here after 38 Bx24. With the blue arrow showing the move.

So i was confused why the recomended move made my winning position an equall one

It's important to note that this "-99.0" does not indicate a high probability of winning.

The actual evaluation is almost even.

The "-99.0" shows that the position has "definitely improved" compared to the previous one.

This is a characteristic of the YaneuraOu analysis tool.

If you make a move on 38 and the position changes, it starts the calculation again.

So the move i made didnt change to postion so it showed 0. Is that it?

The "0.0" represents a standard evaluation of that position.

This value is determined through calculation, so you might see different values if you try multiple times.

By playing the move at 38, the evaluation changed from being just a sign of "-99.0" to a reasonable assessment of "0.0."
