Chess players usually analyse their games and chess positions interactively. They try out moves on the board and let them be evaluated by an engine that is continuously running. Unfortunately there is not always enough time to let the analysis run deeply enough. The opposite method is an analysis that runs by itself, in which an engine examines a position for a long time. There are two ways to do this in ChessBase: Deep Analysis and Cloud Analysis.

 

Cloud Analysis is a deep analysis in which several engines run in parallel, which saves a lot of time and increases the accuracy of the analysis. These engines either run on different computers, or they all run on one powerful computer, on which they have to share the ressources. The advantage of the Cloud Analysis is that the analysis can be carried out without using the hardware and software ressources of the local computer.

 

In the Cloud Analysis the engines adopt different roles. One engine always controls the analysis. Another engine evaluates the candidate moves from original position to make sure that the best possible depth is reached. One or more engines evaluate the possible replies to the candidate moves. Their search only changes when the candidate moves change.

 

A practical configuration is to use two to four engines. One controls the analysis, one evaluates the candidates, and optionally one or two reply to the strongest candidate moves. It is also possible to use several candidate engines if the moves they suggest are different.

 

If the cloud engines run on other computers the analysis continues reliably even if individual engines stop running. This can happen if an Internet connection is interrupted or someone else takes control of an engine. The controlling engine at least must run on the local computer. If additional cloud engines are added they are automatically assigned roles.

 

The function offers the deep analysis of a position with several engines that are running in parallel.
