Chess engines are in general, but in conjunction with scid, I noticed that SF also produces quite a diarrhea of notifications on the pipe towards scid. The scid-end of this pipe is implemented in tcl, and tcl has a tough job of interpreting everything that comes in. Some day I will look into this. Maybe it helps to implement this pipe in C; maybe some of the SF notifications can be "switched off" by setting some UCI options. > The Stockfish engine came with a default setting at 128mb Hash.Is that > too high? I read somewhere that the settings should be between 20-128mb? Hash size is a hairy subject. A big hash kills engine performance if you have many hash misses (simply because it takes more time to find out that you are in a new position). Consider relative weaker blitz games, where unexpected lines are played more often... Hence, increase the hash size with the time allotted for the game. How much hash to actually apply with SF I do not know. You may want to experiment while enabling the Engine Info in the analysis window. This engine info line that appears at the top produces a kN/s figure. You want this number to be high. > Could anybody point me to a resource from which i read about how to best > use these engines within SCID on the macbook pro,on a basic level,please? > Also where can i learn about .bin Opening Books? Check e.g. this: http://wbec-ridderkerk.nl/html/details1/PolyGlot.html Polyglot is essentially a "UCI adapter" - what that means, you can read there - but it has this nice feature of .bin opening book creation from a collection of pgn files.
