Beating an IM

oh yeah, that was an awesome game btw :)

First !

One thing I thought particually about the game, is where did Danny go wrong, I felt my attack built up very quickly. I think it has something to do with the opening.

I hope people will send you "trophies"....

Hi.

Well done on the win!

The game stays in book on Batch Analyzer until White's 15th move which is quite rare in blitz I should think when one of the players is an intermediate.

Here's what the BA automated engine analysis with Houdini 1.5 on a quad-core makes of the game:

You should basically ignore the cumulative match rate figures above because since the sample of non-database moves is tiny, they're meaningless, but I simply include them as a curio.

The analysis above shows move played, then the top 4 engine choice moves in the order move/engine score/depth at which score attained.

So, for example after 20...d4?? (one of the 3 key mistakes by Black) we have the analysis output:

21. Bg5 { Bh6 416 18 : cxd4 233 18 : Bg5 106 17 : fxg7 92 17 }

So you played 21.Bg5.  Houdini preferred 21.Bh6, scoring it +4.16 at depth of 18 ply.  The played move was the engine's 3rd choice, scoring +1.06 at a depth of 17 ply.

Hope that helps.

I have the DVD repetoire by Dzindzichashvili, which has similar lines to the book. I can understand Qf3, pressure on the diagonal and forcing f5-f6 more easily.

@ SteveCollyer

Thanks for the analysis, I got quite excited when I saw the match-up rates, then I realised that three of my moves where forced and easy to find, and it is not so special. :(

Which DVD?  From Roman's Lab series?

Nice one!

I don't get what tool you mean.

And it is from Roman's Forum, mastering the open forum series, crushing lines for white.

GOOD WORK
