The Openings Trainer is one of the most recent and useful web based applications developed by ChessBase
In order to use it you need to go to "Opening Expert Trainer"
The Openings Trainer page has a lot of features on it
So let’s get acquainted with this exciting new application. There are two main functions:
- Organize your openings and
- Remember them through regular drills
The Openings Trainer can be used to learn an opening, but its main function is to help you get organized and better at the variations you have already prepared.
The first thing you do is to start feeding in the moves of the opening you would like to study on the Openings Trainer board. You can make use of the Live Book, which has seven million games, in the form of a tree for this. Below the Live Book you have the Live Database which updates with the latest games as soon as the moves are made.
Let’s say you want to work on the Queen’s Gambit 5.Bf4 variation. After making the initial moves 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Be7 5.Bf4, you mark the 5.Bf4 as your move using the “Mark Move” function.
The mark move function lies on top at the tool bar with other options.
You can also right click on a specific move and mark the move.
You will see an asterisk on top of the move Bf4 and these five moves get added to your white repertoire
As the moves are made, the list of the live database also keeps getting updated. You can see the latest game that happened in this line is the top level encounter between Inarkiev against Aronian from the EU Cup just a few days ago.
After 5.Bf4 you make the moves 5…0-0 6.e3 Nbd7. At this point suppose it is very important for you to remember to make the positional move 7.a3 here, instead of the aggressive 7.c5. So you make the move a3 and right click on it and choose “mark as important move.”
Mark as important move is used when you would like to remember an important move in your repertoire.
You will see two asterisks on your move a3 and the entire sequence of seven moves gets added to your white repertoire
What is described here was a simple line with only one branch. You can add intricate variations lasting more than 20 moves with many branches and save them in your repertoire. Every time you would like to save a particular line just mark the final move (final white move if it is a white repertoire) as “your move.”
Once you have built a decent white repertoire, you can then choose the very unique function called “Drill White”.
With the drill function the computer will take the black side and ask you to make the first white move. As soon as you play 1.d4 it will reply with 1…d5. It will always try to remain in your repertoire until you deviate. Now you can either make your repertoire move 2.c4, or something else say 2.Nf3. If you deviate the trainer shows a message saying “not in your moves” but plays on until it has moves in the live book.
The move 2.Nf3 is not in your repertoire and hence on your right you can see the words
“Not in your moves”. Yet the trainer continues playing and makes the move 2…g6.
The training ends when the moves in the live book end. If you like the new line you can just mark the final move as your move and add it to your white repertoire. Of course, everything that was written above remains true for building a black repertoire too.
Below the notation pane you can see many important functions in the openings trainer. You can download the PGN file, insert text between moves, delete or cut a line or use the annotations palette
When you start marking a lot of moves, the size of your repertoire will increase and then the Openings Trainer will have more options to drill you. You will have your entire opening preparation in one place and also the chance to regularly test yourself on it. This will translate into more tournament points as you will remember your variations better and not forget them in the crucial games!
