Oscillating Stockfish Evaluation on Laptop

I'm using stockfish-9-bmi2 on my laptop to provide me move by move evaluation of games. I've set Stockfish to evaluate to depth = 25 plys. I find that the evaluation provided oscillates move-on-move after a certain number of moves. Below is the plot of the evaluation:



Stockfish evaluation on laptop



In the above plot, the ply-count is on the x-axis, the evaluation from Stockfish is on the primary y-axis (left), the Mate-In number is on the secondary y-axis (right). The Blue line with white circles is the plot of the evaluation and the red circles depict the mate-in number.



However, for the same game, when I jot down the evaluation from lichess.com's analysis board, which is also using Stockfish 9, I get a much more stable evaluation move-on-move. Lichess.com's analysis board also uses depth = 25 for most moves but can use a different number for certain moves. Below is the plot for the same:

In the above plot, the Blue line depicts the evaluation. The break in the trend is because of a Mate-In-3 on ply count = 63.



Considering that both methods use Stockfish 9 and is set to depth = 25, can someone help me with why the results on my laptop oscillates so much?



My Laptop's configuration:




  • OS: MacOS High Sierra

  • Processor: Intel core i7 2.2 GHz

  • RAM: 16GB

  • Stockfish: stockfish-9-bmi2


The game used is Praggnanandhaa vs Vishy Anand - Tata Steel Chess India Blitz 2018

          If I understand correctly your x axis is the moves. Your script implied Anand and Prag were blundering every time they make a move,



          Clearly you have a bug in your script. Stockfish engine always give you a score relative to the player making the move, NOT white. You need to multiply the score by minus one if it’s Black to move.



          Please do this and you will be fine.
