The Komodo Files |
The London Chess Classic did not go well for me. If you include the Super Rapidplay before the FIDE Open, I drew and lost a number of games I should have been strolling on paper. Clearly my chess was stuck in a rut. Probably had been for years to tell the truth. Perhaps it was time to jump on the gravy train and do what all the top players seem to be doing these days: work with an engine.
I asked Chess & Bridge if they could send me a copy of Komodo, which was rumoured to be one of the strongest engines around, if not the strongest. I remember this Icelandic GM telling me about it a couple of years ago at the Scottish Championships and had vowed to get my hands on it ever since. The DVD duly arrived through the post a day later. In trembling anticipation I loaded it up on my laptop.
It didn’t take long before I got an insight into Komodo’s fearsome strength. In a number of training games I was brutally savaged. Press "Ctrl +" to enlarge the comments in the following JavaScript replay board (and Ctrl-0 to switch back to normal).
In my second game in Hastings I was paired against John Anderson. I noticed his theoretical knowledge was fairly good and that he was playing the Slav pretty much every time against 1 d4. To prepare I played a number of training games against Komodo in the Geller variation of the Slav. I think that’s one of the advantages of using an engine. Think how tedious it must have been to prepare for games 40 years ago. You’d have had to lug around these huge great Informators and spend hours flicking through them and other opening manuals.
With the engine it’s just much quicker; you learn how to play an opening exponentially faster. I can charge up Komodo and just play some games with it. So I was playing the Anderson side, the black side of the Slav, and Komodo would take White, just so I could get a feel for how the computer handles the position. Once I felt I’d mastered one sub-variation, I’d move on to the next. Then the plan was to try and replicate Komodo’s play over the board. However, the reader may have already spotted a flaw in this plan...
So my first real experience of preparing with Komodo ended in near total disaster, although that wasn’t the machine’s fault. Only when I was forced to think for myself did the old human frailties come to the surface.
– Part two will follow soon. In it Danny tells us how he used Komodo
to work out a line virutally to checkmate after White's seventh move –

Komodo is a chess program that is different from the rest. Its search makes greater use of extensions than any other top engine, which results in a slightly lower average depth, but helps the actual playing strength significantly. It also allows Komodo to see deeper than any other engine, even if it is displaying a lower search depth.
The evaluation of Komodo differs from its main rivals because, unlike the automated tuning generally employed, Komodo's evaluation represents a blend of both automated tuning and the judgment of a grandmaster and computer expert (Larry Kaufman). The programming team have avoided terms and weights that don't make sense to him, even if they happen to test a bit positively. Automated evaluations are subject to rather large sample error, and applying some chess judgment appears to be beneficial, both in results and in the reasonableness of reported evaluations.
Komodo is primarily known for superb positional play. Of course it also one of the top few engines in tactical strength as well, but the programmers have not been willing to sacrifice positional play just to score better on tactical problem sets. It is generally recognized that all good engines are far stronger tactically than any human player, but that when positional judgment is involved, top grandmasters are still superior in many positions to any engine. Therefore it makes sense to emphasize positional play rather than tactical skill: it is better to improve one's weakest point rather than just to further improve the strongest feature.
Larry Kaufman of the USA is a man of many talents. Not only is he a grandmaster and the
2008 World Senior Champion, but he’s also a shogi expert and the brains behind Komodo 8!
Komodo is especially useful for opening analysis, because as an opening specialist Larry Kaufman has always paid close attention to checking whether the program's evaluations in the opening agree in general with accepted theory. Another point in which Komodo excels is the play and evaluation of positions with material imbalance, which it handles more correctly than other top engines. The endgame of Komodo has been improved by the use of Syzygy Tablebases, which are considered the best for actual play and game analysis as they provide only the most essential information to save time and memory.
Another unique feature in Komodo is its superior handling of multiple processors, using a method that is quite different than the usual one. This is most noticeable when using eight or more cores. There is little doubt that Komodo 8 is and will remain the top rated commercial chess engine on most rating lists.
