A huge Orchestra.. many instruments but they all have one thing in common. They are reading and playing from the same sheet of music. Here are Programmers & Players.. of various talents, and all have their personal experience and background, and yes.. some preconceived notions. Trying to address an issue or enter a discussion and various opinions are naturally Posted. In many cases it's "Apples & Oranges". I would hope we could agree on some very basic fundamentals. This is not just my opinion. These are basic facts. I cannot draw Diagrams here.. But please read the Link! http://articles.roshd.ir/articles_folder/mohandesiScience/computer/Howstuffworks%20How%20Chess%20Computers%20Work.htm This is the simple but fundamental and irrefutable concept of how Chess Computers work. This is the baseline that should be established for any discussion of Chess Programming. I have read all responses and appreciate your inputs. Please if you will now do one simple thing? Start your Engine for a position or at any part of a game. Look at the analysis window What do you see? The analysis module should show the following: The name of the Engine The search depth (brute force selective) Example "12/40" means that all variations were searched to a depth of 12 ply, while some promising continuations were checked down to 40 ply. Next should show the move currently being investigated. Example f4-d6 (3/47) meaning number 3 of 47 legal moves in the position. Next it will show the speed at which the program is running. Example: 403kN/s means it is looking at 403,000 nodes (= positions) per second. This is normal on a 400MHz processor. The main variation for example shows "=(0.00)", then the best sequence of moves the program has found so far, the amount of time it has spent computing on the position,(1 min. 46 sec) and the number of positions it has examined (41937kN =41,973,000) The evaluation expressed in units of a pawn, always from the point of view of White "+0.53) means the program thinks White has an advantage of about half a pawn; " (-3.52" indicates Black is more than a piece up. If Mate is found the Program stops calculating and displays the Mate. (Mate in 6). Anyone have a problem with what I have Posted? Thanks, Chan
