How did I do so bad in this game?

I won checkmate and had the lower centipawn loss than my opponent, yet when you take a look at the computer analysis, the advantage for me is NEGATIVE, and by a LOT of numbers..?



I'm relatively new to chess; yes I joined about a year ago but there was a major hiatus in between that should be acknowledged. I'm still scratching my head at this. What did I do that made me not have the advantage besides the little knight blunder or whatever?

Hey Richard, negative always means black, so -1.0 means a 1 pawn advantage to black. If you look at the graph underneath the analysis board, you will see that black had a large advantage for most of this game

Negative means black's advantage, positive is white's advantage

It is similar also with forced mates, where -#2 means a forced checkmate in two moves, to the advantage of black

Haha!!
It makes so much sense now. I've had multiple games as black where I've completely crushed the opponent and when I went to analyze it, I was bewildered when I saw I never had the advantage(but now I know that's wrong! :P)
While we're on the topic of analyzing.. you guys got any tips for my playing?

Your move 5...d5? loses a central pawn, which he could have taken with 7 Nxe5. You played the opening too fast.

His 8 b3? loses a piece, so there is not much to analyse in this game.
You will benefit more from analysis if you post a lost game than if you post an easy win like this.

Your main weakness seems to be hanging pieces, maybe just slow down and check that every piece is safe / coordinated before making your next move. Also, you seem to resign very early a lot of the time, chances are that if you hang pieces.. your opponents will too and there is always a chance of a potential upset at any point around your level.

John Bartholomew did a great series involving coordination and piece safety (undefended pieces) which will help a lot. Youtube 'Bartholomew fundamentals'.

This one stuck out though, you resigned in a winning position..



Not resigning at all (ever) it sort of crummy, but it's definitely fair and beneficial whilst learning to play out positions.
