![]() ![]() Sure, it might be fun to go surfing the Web while Rybka is chewing on a position, but the problem is this: everything you start/run on your computer requires some level of processor power, and every bit of that power used by another program is being denied to your chess engine. ![]() As a corollary, don’t be using other programs while your chess engine is analyzing. In this post I’ll offer two very simple tips for helping to squeeze every last drop of analytical juice out of your chess engine.įirst, whether your chess engine is analyzing a complete game or just a single position, exit out of other programs you might be running. You might already have guessed where this is headed (at least partially). What we’re trying to do is achieve as high a kN/s value as possible – in other words, to get your chess engine to analyze as fast as possible. You’ll remember from the last blog post that a chess engine running in the ChessBase or Fritz interfaces offers a display which shows you how fast it’s analyzing: the kN/s (kilonodes per second) value. How do we do this? By getting it to analyze more positions per second. We not really going to make the engine “stronger” but, more accurately, we are going to examine methods for getting your chessplaying program to do as much work as it possibly can in the time you’ve given it. So now that we understand that a suggested variation presented by a chess engine after sixty seconds is better than a variation suggested after two seconds, we can move on to the more important matter at hand: how to make your chess engine stronger. Taking the discussion a step further, I’d argue that there’s no such thing as “perfect analysis” anyway, but that’s another rant for another time. If you set up a position and let Fritz12 analyze it for one second, you’ll get a very cursory (and likely relatively poor) suggestion – but if you let it analyze for sixty seconds, you’ll get a pretty good one.Ĭomputer chess programs can’t give “Super-GM” level analysis of a position instantaneously it takes a little time (and, believe it or not, I’ve argued with a few folks down over the years who fervently believe that a chess program should be able to provide “perfect” analysis of a complete game in less than one second. I know there are always people (usually those who are new to computers) who don’t want to believe this they think that a PC works like the computer on the 1960’s Star Trek – ask it a question and you get the perfect answer instantaneously. ![]() So I’ll just leave it at this: in general, the longer the time you allow a chess engine to analyze, the better the analysis you receive in return. I’ve written extensively on the subject before and, truth be known, I’d rather drive a railroad spike into my own ear than write about it here for the umpteenth time. ![]() I’ve mentioned one particular idea many times before and I’ll repeat it here:Ī chess engine will always provide you with the best analysis it can within the limits of your computer hardware and the time allotted for analysis. But before we go there, we need to look at a couple of important (and only slightly technical) details of which you should be aware. We’re going to be looking at using a chess engine for chess training and analysis, not just in the native Fritz12 and Rybka4 interfaces, but also in ChessBase 11. I’ve spent the last few blog posts writing about chess engines (chessplaying computer programs), and it’s for a reason – this is all headed somewhere. ![]()
