{ You can request an analysis of the computer when it comes to analyzing your games, since in this way you will discover your mistakes and you will know what was the correct way to play, remember that mistakes are learned.
This was my first game against a weak player.
This was a game of mine against a good friend, who likes chess but is still a weak player. } 1. d4 { [%eval 0.0] I am going to analyze this game with the help of the computer so that you take this as an example for you to analyze your chess games. } 1...

It's a dubious move, in my opinion. The computer doesn't say anything about this move but, on a3 the white knight is an offside piece, I think 5...Nbd2 would have been more accurate. } 5...

From the computer analysis, can we assume that this 6.Ng5?! it is an inaccuracy. This move does not make sense, it was more correct to continue with development with 7...Be2 as suggested by the computer. } ( 7. Be2 d5 8. c4 c5 9. dxc5 Bxc5 10. O-O Qe7 11.

I probably wouldn't have played like this with more time on the clock, but I can still maintain the advantage in the game. } ( 30... Rf7 31. Rxf7+ Kxf7 32. Rxc8 Bxc8 33. Ne4 Ba6 34. Nd6+ Kf8 35.

Black can think of exchanging pieces, and advance the passed f4 pawn at the end,
to that adding the bishop of advantage, White is lost. [%csl Bh4][%cal Bf4f1,Rc6e5,Yd8d1] } 37. Ke2 { [%eval -12.31] } 37... Be7 { [%eval -6.72] } 38. Nc4 { [%eval -6.83] } 38...

Whenever you play a game, request the analysis of your computer and learn from your mistakes so that you are a great player. } *
