For opening books, the book opening repertoire will be automatically loaded into the opening trainer when youfirst purchase the book. However if you remove the book repertoire from the trainer, or have deleted parts of the repertoire and want to load the full repertoire again, you can use this action at any time.
Opening variations have a per variation 'Drill' button that will launch the opening trainer with the variation selected for revision. Note when launched in this manner 'Review in order' training mode will be selected so that you can traverse the entire variation. If you normally use spaced repetition for training , click on 'train branch' after the position has loaded and that will use your default training method with the variation position selected.
Reading through the repertoire lines in reading mode or study mode. Study mode does not provide an interactive training mode for opening material like it does for problem material. You can use the opening trainer for that type of training.
Move lists are the basic building block of chess relatedmaterial. They can be used as stand-alone objects used to present asequence of moves or can be embedded inside book content such as chessproblems or opening line variation definitions.
As well as holding text content, PGN games can obviously hold descriptions of chess moves. These include full games, chess problems, and opening repertoire moves. There are a series of tags that further specify details for each type, and some tags that are specific to the particular type of chess content being held. The following sections cover these Tags.
You can use RepertoireMoves games with non-initial position in an opening book, however you will need at least one RepertoireMoves game that joins up the missing moves that lead to the initial position, otherwise the repertoirewill not be usable once imported into the opening trainer. For example if all the variations in your book are in the Ruy Lopez, then you can start most of the repertoire moves games from the position after the moves 1.e4 e5 2.Nf3 Nc6 3.Bb5 have been played, but you need at least one repertoire moves game that includes those leadup moves.
You may want to create book material that has comment text in repertoire moves that you only want visible inbook reading mode, and would prefer to not make visible in the opening trainer. This can be achieved byadding the string [%fmt otIgnore] to the comment. For example:
The Opening trainer allows you to create and manage an opening repertoire,and then train to learn the moves using spaced repetition and other drilling modes. The opening repertoire also integrates into thePlay online feature by providing immediate post-game feedback on where your games deviated from youropening repertoire.
If you want to focus only on moves from lines up to a particular depth , then you can set the Maximum learning depth inyour opening trainer settings. When a maximum depth is set , the summary stats shown under the board will reflect the current depth limit. NOTE: Graphs showing training status always use the full depth when displaying data.
To determine how much context is shown, the system looks at the full line from the move chosen for display up to thestart position in the game. If the moves are extremely well known the system may skip them completely, if they aresomewhat less known the system will choose to display them as context, with how well known dictating how fast the systemwill move through the moves. This enables the system to provide you some context, but make sure you are not wasting yourtime seeing context that is already second nature to you. The system may also decide that a move that appears earlierin the line than the move that is chosen for display was close to being scheduled, and so present that move as atraining move before reaching the target move. This further optimizes the use of context by using the context to presentmore than one training target from the context line for training. There are several settings to control the contextbehaviours in your opening trainer settings, including options that can be used to make the system ask you to play ALL the leadup context moves.
Choose between our main chesstempo game database (the one containing OTB games, including master games), a recent snapshot of games played on the playing server (the last 3 million games matching the rating criteria), and your own games played on chesstempo. Each of these has different pros and cons. Using the main game database produces stats that reflect quality game play, especially if you choose a master level rating range for the rating filter. Stats based on move choices in master games will produce a better estimate of move quality than estimates extracted from games played on chesstempo or most likely your own games. Using data from chesstempo games will not reflect the high quality play of the OTB master games, but if you want to use the opening explorer data in conjunction with the common positions first option, the data may better reflect the positions you will experience when playing online, especially if you choose a rating range that reflects players of a strength you regularly play against. Choosing your own chesstempo games as the playing source provides game counts that are very specific to the lines you are playing in your online games, but may lack statistical power in low frequency lines.
There is also an opening trainer wide setting on the opening trainer advanced settings that controls the opening explorer based stats, and can be used to set a minimum number of games before a stat will be used, this can be useful for the win/rate, and opening performance rating colouring methods as smaller game numbers can produce misleading colouring due to small sample sizes, so considering using this setting (which is off by default) if you find low-sample size colours confusing.
Any comments you have made on a position or move in the comment panel, or comments imported automatically from a PGN import will bemade visible in the personal comments panel. You can control when these items will be visible via the 'Show our move comments' setting in the opening trainer settings panel.
You can draw arrows and highlight squares on the main opening trainerboard using right click (square highlight) or right click and drag (draw arrow), combined withCtrl/Shift/Alt key combos for choosing the colour of the square or arrow.
The opening explorer provides a view of the popularity and performanceof moves in the current position. If you are considering adding a newmove to the repertoire, it can be used as a guide to see what masterlevel players are choosing to play in the position, and their successwhen playing each move. You can also turn on the option to show themost popular move in the explorer as an arrow on the main openingtrainer board.
The London System is a popular opening among chess players. From beginners to grandmasters, the London System is considered a very solid variation in which White often gets a playable position with little to no risk of losing. Thus, it is essential to find an opening to take London System players out of their comfort zone.
When I first started playing chess, I used to play the London System with a lot of success. I was able to win plenty of games with White without spending a lot of time studying openings and rather focusing on calculation and strategy. It also allowed me to beat stronger players without worrying about getting caught in opening prep. 1e1e36bf2d
