So why can the priority be lowered for the UCI engines and not for Fritz (and the other engines sold by Chessbase)? The native Chessbase engines are linked as DLL’s to the user interface, which means that unlike the UCI engines they are not external processes. There is no change in the engine’s speed, it only makes the usage smoother. This setting does not adversely affect the performance of a UCI engine! This is easy to test by analysing the same position with both settings. The setting "Lower priority" solves display problems that arise when certain UCI engines are used.Įven when the lower priority is set a UCI engine receives all the processor speed it needs and brings its best performance. Some UCI engines have problems with the default setting because they use too many ressources and the Engine Interface cannot receive the evaluation results and similar data. The Engine Interface runs with low priority to give the chess engine the maximum amout of ressources. : Stockfish 15 : Stockfish 14.1 : Our lawsuit against ChessBase. The communication between the user interface and the chess engine is carried out by a separate program, the Engine Interface. Stockfish is a powerful and open source chess engine. This has to do with the distribution of the processor time. In his latest article for Chessbase, Silver used an analogy: 'In the chess engine world with neural networks, the search is the race car and engine, and the neural network is the driver.' Silver introduced a neural-network-based chess program, called Deus X, in 2018, the same year that Leela Chess Zero was released. What does it mean if the priority is set to lower? In Fritz there is a new parameter to determine the priority of a UCI engine. There is a button entitled "Parameters" which can be used to alter the engine’s playing style. The button "Browse" opens a folder tree that can be used to select the folder which contains the engine.Īfter the path has been selected the fields "Name" and "Author" are automatically filled, as long as the engine contains this data.
I also used this for my cloud-based supercomputer.
To see how I automatically configure this to connect to a cloud-based engine, you can read about how I use a remote engine.
#CHESSBASE FREE ENGINES UCI SOFTWARE#
The program must first be told where the UCI engine has been stored on the computer. Connecting with Chessbase Once it is set up you just point your chess software to the SSHEngine.exe file and it should connect to your remote server. The installation is carried out via an intuitive dialog. The menu Engine – Create UCI Engine opens a dialog to integrate a UCI engine. The program fully supports engines that use the UCI protocol. UCIPlug allows dumping the UCI messages exchanged between a UCI compliant GUI (for ex., Chessbase) and an UCI engine (. UCI is a protocol that was devised by Stefan Meyer-Kahlen and stands for Universal Chess Interfacet. Many chess engines can be downloaded from the Internet that use the UCI protocol. The user interface and the chess program itself are strictly separated and communicate with one another via a standard interface. The program was conceived as a multi-engine chess program and allows many different chess engines to be integrated.
