Removing variations from games using Fritz 13 chess software

We’ve looked at various types of chess engine analysis using Fritz13, including multiple-engine chess analysis in last week’s post, all of which are features in which the chess engine can add replayable variations to a database game. You can also add your own variations to games manually using Fritz13.

But once in a while you may want to remove some variations. For example, you’re annotating a game and have finished and saved a variation, when you suddenly realize that the variation doesn’t work. Or you’ve had three or four chessplaying engines analyze a game and you’d like to remove a few superfluous variations from the gamescore. Continue reading

The “Compare” chess analysis function in Fritz 13

We’ve already discussed the “Full analysis” and “Blundercheck” analysis functions in the Fritz family of playing programs (Fritz 13, Junior 12, Hiarcs 13, Shredder 12, and Rybka 4). But there’s a third method of analyzing games which we’ve not yet considered. I recently saw a comment in which a user appeared concerned that Fritz only pointed out a user’s errors, and didn’t provide an “attaboy!” for good moves in the analysis modes which we’ve previously explored. My response to that concern is that the “attaboys” are implicit rather than explicit; if Fritz isn’t criticizing a move, then it’s safe to assume that the move was sufficient (at least relatively, given the “Threshold” parameter that’s used in the game’s analysis).

But there is a way to get Fritz’s opinion on every move in a game, as well as to have multiple engines analyze a game in one go. It’s called “Compare analysis”, and it’s the topic of today’s uscfsales.com blog post. Continue reading

Fritz13’s “chess dashboard”: the Measurements display

Happy St. Valentine’s Day! While we’re on the subject of that holiday, uscfsales.com is having a special sale to celebrate – I’ll give you the details later in this post. But first we’re going to look at a feature from the Fritz “family” of chess playing programs (Fritz 13, Shredder 12, Junior 12, Hiarcs 13, and Rybka 4), namely the “Measurements” pane. It’s a sort of “chess dashboard” which can provide some visual cues about the presence of important tactical or positional motifs in a given chess position. Continue reading

Generating “threat” identifiers in the Fritz13 chess program

Over the years, I’ve occasionally seen this interesting question appear on chess message boards: “What’s a threat?” For the old chess grognards like myself, that seems like a pretty elementary question, one which we take for granted, but for newcomers to the game the answer may not be at all obvious or intuitive.

Think about it for a moment. How many times do you see the word “threat” (or its various derivations such as “threaten”) used in chess articles, tutorials, annotated games, etc.? As a chess term, it’s pretty ubiquitous, right? Even some of our treasured chess maxims contain the word, such as Nimzovich’s famous “The threat is often stronger than the execution”. Continue reading
