Is there a software that can rate your games?

Is there a software that can rate how well i preformed in a game i want to know how good my games are and when i play better than my rating.

No. The problem is that playing the best moves does not guarantee a win. You can have a winning position for 30 moves and then have that become totally irrelevant after you make a blunder. Your moves can not be accurately judged independently of the result.

Let's say you could memorize a line and play 20 moves exactly the same as a Grandmaster but then gave up a mate in one on the first move after the line ends. How do we rate your moves?

DragonPhoenixSlayer,

Interesting question. I don't know of any such software, but I suspect it wouldn't be difficult to write, since it could just take the analysis output by this site, count up and average the inaccuraries, mistakes, and blunders, and using weighted average give an average playing level for the game, maybe based on gathered statistics that correlates rating with the mentioned weighted average.

notmtwain,

You're right as to the outcome of the game, but I believe on the average such software would work pretty well, especially if the assessment were based on at least three parts: those three mentioned components. It's just a case where the answer is multidimensional, like in film ratings (nudity component, violence component, language component, etc.).

P.S.--Somebody out there want to hire me to write it?

Maybe I am misunderstanding what you actually want, but if you are looking for a program to analyze your games and tell you what you did right or wrong, Fritz is pretty much "it" nowadays.  Chessmaster: Grandmaster Edition, which is more than a few years old at this point, is also a good program if you can still find it.  Then there are free chess engines like Stockfish that also analyze games.  I prefer Fritz (currently using Fritz 14)  and Chessmaster because they both provide "natural language" analysis that uses words rather than just numbers to point out where you went right or wrong.  

I'm not aware of software that does this. I certainly haven't seen Fritz quoting rating estimates based on game analysis - which is what DPS is looking for.

You could try to play against engines that are set to different ELO levels and see which ones you can win against, which you draw and which you lose to.

OMG, that's interesting!

Chessmaster software used to have a section where you could imput your games and it would guestimate your playing strength in the game by which moves you played, but that was 16 years ago.

first of all, chess is not new, secondly, there isn't a program which can rate a move in any given game!? How is that possible, there are countless lives wasted on the devotion to chess; almost an infinite chess game database.  We are moving toward landing people on the surface of Mars yet have no programs to rate a chess move.  I read excuses but not good founded reasoning to not having a program to rate a game per move. We can predict the best weather conditions to land on a planet millions of miles away with just over 115 years experience, yet with chess' more expansive history cannot rate one move. We are a silly species.

My two cents, I don't know if there are specific rating engines like that, i.e. one saying you're such and such a rating having looked over your games. However, you can play against Shredder engine in a mode where your rating goes up and down as per your results, and the engine adapts its strength after yours. So, say that you start at 1000 and win against the engine (playing at 1000 strength). Then you're rating goes up a certain number of points, say to 1250 or something. Then next game, you'll play against the engine at 1250 strength (because that's your current performance). When you draw your rating stays the same, lose and you drop points. The jumps up and down gets smaller and smaller the longer you play, because the performance is based on more games.

Rating individual moves doesn't really make much sense, though. I mean, if you find the first move in a sequence of say five or seven moves, what's that worth? It's impossible to know whether you actually found the move by a fluke, or whether you more or less have seen the entire sequence. And then, what if you execute the sequence in the wrong order? You've seen the idea or the motif, but overlooked a nuance. It happens to everyone. World Champions have overlooked mates in one, dropped queens in one etc. They still became World Champions.

Arguably, rating individual games makes very little sense, it's impossible to say much about a player's strength from one game only. This is one of the reasons why the k factor in the Elo rating system changes after the first 30 games.

Exactly. There are many things you can do to try to gauge this, apart from tracking your strength via an engine. An old method is to note the time you use per move (in OTB chess). Then when you go through the games afterwards, you can compare the clock times with the progress of the game. Say that you tend to blunder around move 25-30, you're probably having issues finding and implementing certain middle-game concepts, or that you tend to get into time trouble early (this could be a sign that you need to improve your understanding of openings, or that you're generally indecisive) or that almost all your blunders come when you've used only a small amount of thinking time (and need to learn to double-check for blunders before moving). And so on and so forth.

You seem to have an inaccurate idea of just what a "rating" is.

A chess rating is a number that relates your statistical win-loss performance to the pool of chess players that you were playing against.

So no, you cannot assign a rating to an individual game, and still less to an individual move.

Even if you could assign a rating to a single game, the result would be essentially meaningless because of the granularity issues... your "pool of opponents" is limited to a single player, and your "win-loss performance" can only be one of three values: 100%, 50% or 0%.

A valid statistical treatment (which is what a rating represents) requires a far larger data set.

Computer desktop software that can rate games are at this point, and how far as I know, the following:

Fritz Chess

HIARCS Chess Explorer

Lucas Chess

Sure MelvinGarvey, anyway the question was about software that can rate play in a single game, not the accuracy of that rating; for accuracy you need a good sample and easy statistics.
