“Deep position analysis” in the Fritz/Rybka chess playing program

If you haven’t yet read the immediately previous post to this blog, I encourage you to do so – otherwise the rest of this post might not make much sense. In that last post, we discussed the difference between the way an over the board (face to face) chessplayer analyzes a particular board position, and the way a correspondence player would analyze the same position. The over the board player must look at a static position, decide on two or three candidate moves, and try to mentally visualize the consequences of each candidate as far ahead as he can. That’s exactly how a chess program like one of the Fritz family (Fritz, Rybka, Hiarcs, Junior, and Shredder) analyzes a position in “Infinite analysis” mode. A correspondence player, however, is free to move pieces around, examine many, many candidate moves and, after deciding on one, move a piece physically and analyze that move, deciding on candidates, etc. (often by moving pieces without the necessity of “in the head” visualization) and record the moves/analysis as he sees fit. That’s similar to the style of computer analysis (which I call “creeping” analysis) which was discussed in the previous post: manually advancing the engine one move at a time, each time adding the top-evaluated candidate to a growing line of analysis.

“Creeping” chess analysis in Fritz/Rybka

In the previous blog post we examined a basic use for the “Infinite analysis” feature in the Fritz “family” of chess playing programs (Fritz, Rybka, Hiarcs, Shredder, and Junior). This time around we’re going to learn another way to use this feature, a method which is a bit more time-intensive but which yields interesting results. Continue reading

Infinite chess analysis mode in Fritz/Rybka

I’ve had a couple of interesting conversations lately with users of the Fritz “family” of playing programs (Fritz, Rybka, Hiarcs, Junior, and Shredder) who weren’t quite sure what “Infinite analysis” does, or, in one case, what it can do for them. “Infinite analysis” has a lot of uses, all based on the idea that you feed a position to the chess engine and let it chew on the position to find the best sequence of play. It’s not terribly different from the way we human analyze when we’re playing a face-to-face game: we try to figure out the best move, followed by our opponents’ best reply, followed by what we’d do next, etc. – it’s the old “If I do this, he’ll do this, then I’ll do this…” thing. The difference is that a chess engine will look much farther ahead (“deeper”) than any human could do, as well as pick better moves than we average players would normally choose. Continue reading
