How to use post game analysis effectively.

Hi all. I always want to learn from games played and use post game analysis. So after it says my move was a mistake or whatever I tap on the magnifier and it takes me through moves that the computer would recommend. However when I run through these “computer” moves often it says inaccuracy or mistake. Why is this? Also my last two game reports each said on the “throwaway “ “one player was winning, then blundered it away”. One of those I had an accuracy rating of 93.7 and my opponent 94 ending in a draw. The other my accuracy was only 37.4 against my opponents 78.1. There is no way I was winning at any point in that game and was beaten easily by better play. Any help in using analysis appreciated. Thanks

Well the analysis of your last game shows, that you had a winning position after nine moves. If you had played the nice tactic 9..Nxc3 (his Bishop on d3 is hanging) you would have been around two pawns up. So one way to use this game analysis could be to train more tactics - you can use chess.com's tools for that.

Not sure because after Nxc3 Queen can just move out to protect bishop. However my more important question was the first one. Why, when I tap on magnifier and go through computer suggested moves is there so many times that those moves are “inaccuracy” or “mistake”. surely these should be best moves?

Even if he protects the Bishop you have won an extra important pawn. But I am not sure that I understand your question. Do you think that 9..Nxc3 will come out as a mistake? It is quite seldom that the best computermove will prove to be a mistake when you give the engime more time to calculate. But of cource it will often end up with a better first move. Can you give an exampel on a proposed move that turned out to be bad? 

I wish to print off my games analyses, however I am getting a pop-up message telling me that I do not have the relevant app. I am running Windows 10. Is anybody able to give me any help?

Thanks for your help Toldsted. Ignore that one example for now. What happens when I go through post game analysis is this. I click through my moves and it might say inaccuracy or mistake, and there is a small magnifying glass which I click on and then in brackets there are the moves that the computer suggests which I follow through to see where they lead. OK so far....BUT then when I am clicking through those moves suggested by the computer those moves themselves often flag inaccuracy or mistake. I thought these computer suggested moves would all be “best” moves to learn from? I wish I could post an example or a pic I took of the screen shot but can’t seem to do that.

Ok. The computer are best at figuring out the best move in the position. Then it also gives the line it consider best. But the longer you go in the line the less time it have used calculating the moves and the greater possibility for a mistake (= given more time to calculate the engines funds a stronger move). Only seldom does this mistake influence the original best move decision (but it happens and this is what correspondence chess players try to use against their opponent). Chess is still complicated also for engines! But you can almost always trust the engine when it says that you made a 'mistake' like not playing 9..Nxc3. 

Ah, thank you Toldsted , that does make sense. I was getting frustrated trying to work out why it happened! I appreciate you taking the time to comment to help me.👍

Try using this game as an example:

The "report" generally uses low depth and isn't always "accurate" itself (ref. move 5...Nf6 in the game).

 

This has actually been a pretty useful thread, thank you 

How did you do the in game notation thing, i cant figure it out.
