Well I think it's a nice win because you were never in trouble, goes to say that the evaluation was always to your advantage probably.
In fact the analysis system is broken, but you definitely should have spoke about the brilliant move controversies and the CAPS averaging as well, I played an extremely chaotic games with 2 blunders by me and 2 missed wins from my opponent, we both got 90+% I couldn't believe it
I see people all the time complaining on here about the Analysis grading system. Everything from bragging about a 99 to using it as a basis of accusations and everything in between.
Well, this post will put the complete kibosh on the validity of the entire system.
Take a look at the following game. It was about as chaotic as can be. Everything from Black playing screwy, pathetic moves to it being a 3-minute game, which means no way White (myself) plays all the best moves, and I don't play all the best moves. Actually, I am sure I made numerous mistakes (remember, this is not a brag post, this is to show the Analysis system is crap).
Well, I just ran the Analysis bit to see what numbers it gave.
mid 60s for White
mid 20s for Black
At game conclusion, it says "Nice win. You were never in trouble."
I may never have been in trouble. But how on earth can anyone say that 66 or 67 is a "Nice Win". The whole game was crap with just a cute end to it where a pawn mates and it opens up the Bishop to cover the escape square and otherwise Black self-blocked himself.
This is NOT a "Nice Win". This is "eh" play by White and terrible play by Black
"Nice Win" - PA-LEEZ!
