Analysing with Fritz 16

by Martin Fischer
3/11/2018 – Today, in the time of strong engines, analysing chess games seems to be easy: fire up the engine and let the computer work out the lines. This is useful but does not help your chess as much as analysing actively. ChessBase offers a lot features that help to analyse, from entering games to analysing professionally. | Drawing: ChessBase

Analysing with Fritz 16

Let's assume you just played a game (maybe in a tournament, maybe in a club match) and on your way home the game is still very much on your mind. If you have time and a mobile device you can use the ChessBase Web App "MyGames" to enter the game into a cloud database. While entering the game you have access to the LiveBook and you get a better understanding of the game because the engine indicates tactical errors. Later, you can access the game in the cloud with all other devices by using your ChessBase account.

The cloud: you only need an internet browser to access your data.

At home Fritz 16 is the best tool to analyse. Click "ENTER & ANALYSE" on the starting screen.

Fritz 16

A new function in Fritz 16 is "Resolve Score Sheet Problems". This helps to reconstruct the game when a move is missing or you wrote down a wrong move in the heat of battle or when you enter games of other players.

Coaches like to stress how helpful it is to analyse games without an engine. But of course you can also turn to Fritz immediately: the basic mode for analysing is the function "Infinite Analyses" (under the menu "START").

Infinite analysis

"Infinite analysis" tells the engine to analyse the position that is currently on the board. The "Let's Check" function tells us whether other players analysed the position in-depth and with strong engines. 

Full analysis

Tactical analysis

Another option to analyse games is offered by "Full Analysis" (under the menu "START" and "Analysis"). This function helps to find errors and inaccuracies in games.

The program adds comments and lines to the notation, considering the following:

  • Opening theory
  • Tactical motifs, strong moves, combinations, piece sacrifices, double attacks
  • Possible errors and inaccuracies
  • Weak moves which were not played (to answer questions such as "Why can't I take here?"). Usually, the reason why a certain move would have been bad is indicated
  • Threats and attacking motifs
  • Defensive ideas, attacking possibilities, manoeuver, endgame classification and game results that are not logical


The tab "Analysis" lists the main functions for analysis

1. Blunder Check

"Blunder Check" does not lead to a comprehensive analysis of a game but runs a purely tactical analysis to find errors. The dialogue offers several options to find the biggest error.

2. Deep Position analysis

"Deep Position analysis" analyses a concrete position, but not the whole game. This function is very useful for a detailed analysis of critical positions. For correspondence players, it is extremely important. The function creates an analysis tree for the position in question. You can tell the program how deep it should analyse and how comprehensive the analysis tree should be. Moreover, you can define which kind of moves you want to exclude from the analysis.

3. Let's Check!

"Let's Check" saves time. This function allows you to access all information saved on the Let's Check server, including the analyses of positions which countless engines have analysed in detail, sometimes on powerful computers: "Let’s Check" contains analyses of more than 200 million positions, including the endgame turbo with 5-piece endgames and the most important 6-piece endgames!

4. Compare Analysis

The results which different engines arrive at can be compared with "Compare Analysis". This helps to see the strengths and weaknesses of different engines.

5. Shoot out

"Shoot out" leads to an engine duel — engines play a certain position against each other. This is an engine test and helps to evaluate the most common endgames or middlegames better.

6. Monte Carlo

"Monte Carlo" tells the engine to play a huge number of games against itself. The results are shown in a statistical tree. However, not all engines support the so-called "Monte Carlo Analysis": only the engines developed by Vasik Rajlich (Rybka 3 or 4 — including the Deep versions — Fritz 15 and Fritz 16) support this feature.

Deep Rybka 4 Multiprocessor Version

For years now Rybka has dominated the computer chess scene. No other program has been able to achieve a similar increase in playing strength. For chess analysis Rybka has long become one of the most important analyis tools of professions and amateurs alike. So that this state of affairs will continue in the future, the Rybka-team gathered around programmer Vasik Rajlich has developed a new version which is even better: “Rybka 4 plays more aggressively and more tactically”.


Cloud Engine

If you want to analyse a position with a top engine running on strong hardware you can rent an engine that runs on another supercomputer! You always have access to superfast computers which calculate more than 100 million positions per second — which is 20 times faster than a normal PC. And you do not need resources from your own computer - that's how modern professionals analyse today…

Just give it a try - you will see that analysing with Fritz is more than activating "Infinite Analysis".

Fritz 16 - He just wants to play!

Fritz 16 is looking forward to playing with you, and you're certain to have a great deal of fun with him too. Tense games and even well-fought victories await you with "Easy play" and "Assisted analysis" modes.

@Martin_Fischer: Thanks, Martin.

@ celeje: The precision feature is part of Tactical Analysis. It will be working in every game you check with Tactical Analysis. The precision feature shows you how much your game is identical with engine play, not counting easy recaptures,legally or virtually only moves.

@Martin_Fischer Many thanks for taking the time to answer.

@ Martin_Fischer:

What about the precision % feature for White or Black?
Will this be available in Fritz, ChessBase &/or Playchess for users' chosen games/sides?

@ notebook03: If you opt for fine in tactical analysis, the program will comment on almost any move were, according to the engine, a better move, even just a little bit better, was available. In the case of medium the missed move has to be significant better and in the case of coarse the played move has to be a blunder to be criticised. The program do not use fix numbers of centipawns, but will use other factors, like the length of a variation for example, too.

My recommendation is to think for whom you are doing the Tactical Analysis: Do you analyse games from Beginners or do you look for combinations (played and missed ones) coarse might do he job. If you do analyse top games you may opt for fine.

What do the Fine, Medium and Coarse options do under Tactical Analysis? Is it a metric, like centipawns? If so, what's the difference between them? By the way, I can't find the answer to this in any of the Fritz documentation.

@ genem: With Fritz you always have the option to look at any given position from White's or Black's point of view. Simply press X when runnning an analysis and the program will switch the right to move. Therefore it is indeed quite easily to have a look what is threatening or which options both sides have.

Fritz' self-named feature of "Full Analysis" is better understood as only half-full.

After White's 14th move, of course we want to know what Black's best reply move or moves are. However, according to more chess authors than I could hope to count, a good player as Black also tries to understand what new positional or tactical options White created for himself with White's 14th move. Do not consider only your own pieces.

So why does ChessBase refuse to offer its paying customers the option of telling Fritz to report the best move for BOTH White and Black, regardless of which color is on turn? Who understands a studied game better - the student who does know what the color off-turn would like to play if it was his turn again right now, or the student who does not know?

The article claims: {"Today, in the time of strong engines, analysing chess games seems to be easy"}

No, until the half-full analysis feature is improved to be a full analysis, it is not easy to fully analyze a chess game. It is implausibly time-consuming.
