It saw the mate in 8 immediately (less than half a second) when I ran it (after 44.. Nb5). Maybe your phone needs an upgrate or it's time for you to get rid of Windows 95.
Quick chess analysis needs an improvement.
@notmtwain No, of course the analysis thatchess.com has that`s done by position (when you click under learn, then analysis, the tool that analzyes one particular position) is quite good and powerful. I`m talking about, when you finish a game, there`s the box that says "quick" analysis up until "maximum," and it plays out the game and comments as it goes (with things like blunders, mistakes, inaccuracies, and the average difference).
Yes I realize that we are not paying but the quick chess analysis makes some grave errors that probably throw a lot of people off. Check out one of my games and what the quick analysis suggests on move 45
