How to get Fritz13 to explain all the moves in a chess position

A typical chess position can contain a couple of dozen (or more!) legal moves, and a beginning player often can become overwhelmed by the possibilities, neither knowing nor understanding the point of a particular candidate move. Likewise, every chess player (regardless of their level of experience) should look at a move his or her opponent has made and always immediately ask, “Now why did he play that?”

It’s not always easy to understand the point of a particular move, whether one is a beginner or a grizzled veteran – heck, I’ve been playing for many years and I still often find myself wondering why a particular move was played. The Fritz family of playing programs (Fritz, Hiarcs, Junior, Shredder, and Rybka), chess playing software which is available from uscfsales.com, contains a feature which can help point you in the right direction when you’re trying to figure out the reason behind a particular move, a feature called (not surprisingly) “Explain all moves”.

“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

The Fritz/Rybka/etc. chess program’s shared user interface

I’ve recently received a few panicked phone calls and e-mails from new users of two or more of the Fritz family of playing programs (Fritz, Hiarcs, Rybka, Junior, and Shredder). “I just double-clicked on the Fritz12 icon and it launched Rybka4! How do I get my Fritz back???”

The fact of the matter is, your Fritz didn’t “go” anywhere. Both chessplaying engines share the same user interface – the “wrapper” containing the on-screen chessboard and all of the program’s various user commands. Continue reading

Automatic multi-game replay in Fritz/Rybka

One of the first features of the Fritz family of chess playing programs (Fritz, Rybka, Hiarcs, Junior, Shredder) learned by new users is how to manually replay database games by using the keyboard cursor keys or the on-screen VCR buttons. But more than a few folks don’t realize that they can load a database and have Fritz, etc. replay the games automatically, one game after the other, while they sit back and watch. Continue reading

Post-game chess engine analysis: zeroing in

Although I’ve stressed in prior posts that a chess engine, such as one of the Fritz family of playing programs (e.g. Fritz, Rybka, Junior, Hiarcs, and Shredder) can best be used to point out chronic recurring problems in one’s chess play over the course of many games, you can also use a chess engine to zero in on a particular problem point in one of your recent games.
