I have intentionally eschewed it Dave.  Chess is such a cool game, it can devour one’s life.  I might download it to analyze these games however, unless someone beats me to it on game 5.

I should not have used the term “evidence” but rather “indication.”  Evidence proves something, in sufficient quantities.  Indications suggest something, in sufficient quantities.  Read on please.

That would indicate an Elo rating for Alpha of about 3565, waaaay the heck above this year’s TCEC champion Houdini 6.03 with its paltry 3412.

Dave, do you play?  What did you think of f5 in this position?  It still loses I think (everything does here) but loses slower than that awful Kh8.  Kh8 looks like something one would find in a basket of deplorables.  

 

Do you have StockFish loaded and ready to run?  Anyone else?

 

 



 

If you can find a way to get StockFish to offer Kh8 here instead of f5, we might be the first ones to indicate all is not what we are being told.
