3.13.6 Can variations and evaluations be manipulated?
Since Let's Check is open for all engines it is possible that old, bad or manipulated
engines can be used. Destructive content is always possible whenever people can
share content in any form of online community.
The hardware power and the processing time of variations play a role, so it will be
difficult to falsify an analysis even if an engine has reported having made the deepest
analysis.
In the Let's Check window we also see how often a variation has been verified by
other users. The system cleans itself, and so unverified variations and the obsolete
evaluations of older engines will disappear with time.
3.13.7 Can senseless moves be input and analysed?
All legal positions and moves are valid for analysis. Rarely visited moves without deep
analysis expire after a while.
If you don't want to see any senseless moves you should check the option "Hide ra re
m ov e s".
3.13.8 How are the Let's Check honours lists created?
Points are awarded for winning a variation. The number of points depends on the
popularity of the position and the time spent calculating it. The starting position is the
most valuable position because it is visited the most. If you lose a variation to
someone else you lose some of the points you were awarded for winning this variation,
so your points can fall when you are not active.
3.13.9 What do the two diagrams in the LiveBook window mean?
The left (or upper) diagram shows the most popular position, i.e. the position that is
being analysed by the most visitors. The right (or lower) diagram shows positions that
have been reported as discovered or won in the Chat window.
