    Cenerentola is in the comp I've entered, advice? Do I bother making a move or let the clock run down? In saying that he could beat me without the help of an engine???

    My first choice moves only score 43% with Houdini.

    But I'm winning loads of games with my 43%. The machine know nothing!

    In both games my 4th highest score which should be my highest
    comes nowhere near any of his scores.
    This is depressing me. I'm awful.

    Are these figures not kind of bias because of the massive grade difference.
    and I did not get a chance to play good moves instead of two move tricks which
    require the only a few replies. Meanwhile my position goes further downhill.

    (I have another games with him...gonna to resign them.)

    How about this game where our grades are similar and I know I played some
    good and only moves. I must be better than 43%. (I'm sulking about this...I want to be good.).

    I thought this a draw till White gave up the e-file. Then I started looking for Knight
    Forks and Hook Mates.

    This is excellent analysis.

    I know you have just run the games through a computer but hey surprise surprise!

    If like me, the best way you can think of to improve is to play a few games and then to peruse the blogs that Greenpawn supplies us with, then for those that can't see what this represents, allow me to elaborate.

    The themes throughout Greenpawn's blogs are mating patterns, blunders, sacrifices, attacks, checking checks etc. He trawls our games, he displays our human weaknesses, he humbles us and we learn. I find his blogs educational, informative and entertaining, he is our own BBC! Yet despite his brilliance, he only matches at 46%! Anybody achieving 40% above this benchmark should provide a similar level of enlightenment...

    I think the 43 is false, I want 60-70-80.
    either that or I challenge that computer to a game.

    I think it's cos I sac something, either a piece or my position,
    then the other lad has to play exact from crisis to crisis till they win.
    I need blunders to win, I cannot recall simply outplaying anyone
    by playing legal moves. I played against him what I play against
    everyone. I try to keep the pot boiling. I hate retreating...alwasy have.

    Gosh you lot must be playing 25% 1st choice.

    It looks like White was trying to play Rb5, and didn't realize he went one square too far. Black's queen was trapped. If this was an OTB game, this wouldn't have happened.

    I think it could happen OTB- I have seen some funny blunders, many of which I made myself.

    One year at the US Open I got up to go to the restroom, and when I came back, I sat down at the wrong board- it was the one next to my seat. I was "in the zone" thinking about the position, as was not paying sufficient attention.

    I sat all the way down, looked at the board, became completely disoriented by the position, looked up at my opponent, and then realized what I had done. It all happened in the space of a few seconds, and we all laughed.

    I have also grabbed the wrong piece, grabbed the right piece but placed it on the wrong square, and hallucinated a tactic because I thought my queen or bishop was on a different diagonal.

    And don't even get me started on OTB pawn endings...

    I think it's cos I sac something, either a piece or my position,

    I need blunders to win, I cannot recall simply outplaying anyone

    Against an opponent finding lots of engine moves you'd expect not to score so well as there is less in the position to latch onto. I'm sure against more human opponents you'd find the 43% figure go up as they make mistakes you can agree with the machine about.

    43% is not necessarily bad if this is based on a 30s/move Houdini analysis. That will not catch many of the best moves. I ran some tests and found that close to half of the moves rated best by 30s Houdini are not actually the best move, I will paste a PGN below of a game I ran between Stockfish and Komodo where they had an hour per move. and a 30s Houdini analysis of the game, excluding the first 5 moves. Only 55% of the one hour Komodo moves and 64% of the one hour Stockfish moves were Top 1, and you can bet the one hour moves that were not Houdini's top choice were better than Houdini's choice. For 1 hour Stockfish, only 88% were Top 3.

    Such percentages are not positively correlated with play quality at the top levels. At some point the percentages go down with increasing player strength because the engine's positional analysis is pretty weak and the engine's overall ability relies on brute force, which is limited at 30s/move. I am sure that a super GM would find some of the better moves that 30s Houdini does not and so this kind of analysis would probably imply that a super GM is not as good as a 2400 player, or even Cenerentola.

    The analysis posted earlier certainly does not confirm Cenerentola is using an engine. In fact I would say that it at least implies he is not using an engine doing one hour per move analysis because his percentages are too high. I did an analysis of another Komodo-Stockfish match where I only gave them 5 seconds per move. 30s Houdiini put 98% of Stockfish's moves in the top 3, so 30s Houdini thinks that 5s Stockfish is much better than 3600s Stockfish or Komodo!

    I could not get the pgn to post properly, but here's the analysis:

    I think you totally misunderstand what the analysis is designed to do.
    The analysis I posted simply shows how engine-like each player was, given the same conditions for both players. It's not designed to find the de facto best moves in any position.
    I've tried running analyses for different durations per move & it really makes very little difference. Different engines often give slightly different results, and Stockfish often varies with Houdini, Rybka etc.
    What you can say, given the parameters I used for those games above is that Houdini very much agrees with one player's choice of moves & far less so for the other.
    Another issue is that I doubt very much idiot cheats on this site have their engines running overnight on a particular move. Most log in, fire up the engine, wait a minute or so & then play the move of their choice that doesn't drop more than 0.10 of a pawn!
    A decent hash & cumulative analysis as I have done mimics that process very well, whilst also being practical & not taking 6 weeks to get analysis for 20 of a suspect's games.
    If you're really interested then you should look at the work done by various people over on chess.com where the basic analysis that I'v done has been taken far further by various programmers & it's a site where they do still investigate & ban idiotic engine users.
