Before jumping straight into the new feature in the replayer, for those still getting used to the features it has, here is a quick look at the main ones that are bound to be used the most often.
Replaying moves
Obviously you can use the arrows under the board to play a move or take a move back
However you can also just use the arrows keys on your keyboard
Engine analysis
One of the unique features in the ChessBase replayer is the engine analysis. If you click on the engine button (looking a bit like a fan), it will open the Fritz engine and start analyzing the position. You do not need to own it or have it installed!
It may take a few seconds to start the first time, but once it does, you will see its evaluation and analysis under the board
Analyzing a game
If you wish, you can enter your own moves directly on the board, moving the pieces with your mouse, to see how they look, and consult the engine (see above) to see what it thinks.
Saving games
Needless to say, you can save the games. You have two options to do so, depending on whether there is only one game to save or many.
If you see a list of games below the board as above, you can choose to save them all into a PGN file for your computer by clicking on the diskette symbol below the board. This diskette will only appear if it is a base.
If you have only one game, or only want to save the game you are looking at and not all of them, then click on the diskette symbol under the notation. It will save only the opened game, but it will also save any analysis you made as well.
Opening in Fritz Online
This is the latest function added to the replayer, opening a slew of training possibilities. A common training exercise is to take a position that you would like to master and practice it by playing against someone or against an engine. Many times, the problem with the second choice is that the engine is just impossibly strong and finding a more balanced level is not always easy. With Fritz Online though, this is simple.
Let’s look at a dynamic game with plenty of fun tactics and complexity. For this purpose, here is David Navara – Hikaru Nakamura (2014), a full-blooded Classical King’s Indian. The analysis was done by GM Stohl for ChessBase Magazine and can also be found in Mega 2016.

The analysis is certainly fascinating and thorough, but there are always things to look at. Consider move 21 by White. Stohl states that 21. Nf3 was an inaccuracy and that 21. Qb2 was better, or even 21. Ra2 as suggested by Navara himself. Feel like trying to play this position as Black to see how you would fare?
First click on the move you wish to face, such as Navara’s 21. Ra2.
We must first promote this move to the main game as the function only works with main moves
Then go to the toolbar under the notation and click on the “-> Fritz” button.
It will immediately take you to Fritz Online, with the game and position. You will notice that the other moves after have been discarded. Afterall, the idea here is to practice this position.
You can now flip the board if you prefer, but more importantly you can select the level Fritz will play at. What is what? Suffice it to say that Beginner and Amateur will see it blundering quite a bit, while Club Player less, and Master and Grandmaster even less. If you are rated over 2000, you will probably prefer Master for a more interesting challenge.
Don’t forget that in Fritz Online you also have the training tools such as Assisted Calculation that can help you work your calculation and visualization skills. For more on that, be sure to see the article explaining how it works.
