164 Houdini Help 3.5.15.2 Can Let’s Check be used anonymously? Let's Check can be used without logging into a Playchess.com account. In this case you will receive no information about who analysed which position. 3.5.15.3 What does it cost? The use of Let's Check is included in the price of the program. It is guaranteed that the program will support this feature until the end of 2014. 3.5.15.4 What difference does the power of my computer make? The program regularly performs speed checks on your computer. Fast computers are at an advantage. By contributing your engine you can process more positions in the same time and win "credits". Deep engines also have a strong advantage. Analysing in multi-variation mode needs more time. If you log into your Playchess.com account your "speed index" will be displayed in the Chat window. 3.5.15.5 What engines are allowed? Every engine that can be used in the User interface can be used for Let's Check. 3.5.15.6 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. 3.5.15.7 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". 3.5.15.8 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. © ChessBase 2012
