Running to find out the engine's name?Weirdly since restarting the software it seems to be working better would say this definitely looks like it is working now? I don't know why its so fiddly to start a new game though against a different engine though but thought what I have written above may help someone in the future. I can't see it executing the stockfish exe at the system level in task manager this is possibly because its executing it withing the software, like a sandbox?

I'm not sure why you can't find Stockfish in the task manager. I guess it's possible that it's being sandboxed, but none of the GUIs I use do that. In task manager, make sure you're looking at processes and not applications. Sometimes it helps to click on the "% CPU" column heading so that the processes using the most CPU are at the top.

I noticed several posts that people say engine evaluation like +2.00 is nothing. Statistically +2.00 in opening means one side is about 90% of winning. (endgame evaluation with +2.00 and flat will mean nothing and likely draw though). It is understandable that people cant follow what stockfish think , that is millions of postition per seconds.However, these are tools that you can use to visualize stockfish evaluation. Here is position of stockfish evaluation SF see likely forced win from white, at depth 48. SF recommendation is Bc6 to save bishop and win the game, But if OP play Ba6, SF is happy to trade down that bishop with kt and can make a draw for white. Conclusion, Bishop is more valuable in that position and black will likely win by saving bishop with Bc6.It is impossible for people to visualize what engines are thinking, so we usually do additional variation board on right side (by right click on the borad, and open the view)In additional visualization window, people can see how stockfish think move by move.Stockfish evaluation always come from the end of prinicpal variation, so go to the end of principal variation and you will see which position SF is evaluation as +2.13(for example)And again, if you still dont understand what +2.13 means? you can copy and paste that PGN into stockfish static evaluation here, like that. There you can see, every thread, mobility etc that should explain every single detail of what +0.01 means.

It sure would be cool if you could feed one of your games to a chess computer, let it analyze for a while, and have it spit out a multi-page plain language commentary about your chess strengths and weaknesses, including several paragraphs about your pawn structures, and a breakdown of your endgame play.Yep, that would definitely be cool.But it won’t happen. At least not anytime soon. Many computers can understand voice commands (as long as they’re programmed to do so), but they have the devil of a time using natural language to talk back to us.Some chess programs claim to offer game analysis in such natural language and they do, but it’s mostly smoke and mirrors. The responses are “canned”, that is, pre-programmed and often not very informative.A chess computer can give us a whole lot of input as to what we did wrong in a game and how we could have played better. Over the course of many such analyzed games we can also spot tendencies in how we play, categories of mistakes that we make over and over again, which will show us what problems we need to correct in order to improve. But to get that information, we’ll have to meet our computer chess coach halfway.It can’t learn to use our language but, believe it or not, it’s actually pretty easy for us to learn its language.The main thing to remember when reading a chess engine is 1.00 equals a pawn, and positive numbers mean that White’s ahead. I’m serious. At its core, it’s that easy.Reading Stockfish Chess Engine (Analysis Free)In one of my previous posts “How do Chess Engines Work” I addressed how computers play chess by using a formula called an algorithm to assign a numerical evaluation to a particular position.The Stockfish engine looks ahead as far as it can, evaluating millions of possible future positions, “backtracks” the numbers, and ultimately plays the one candidate move which leads to that best position.What’s even cooler is that the computer will show us what it’s thinking. Pretty dang near every chess program ever made has some form of “analysis window” in which it will show the user what moves it’s pondering at any given moment.The best way to illustrate how to read the info in a Stockfish analysis window is by using a practical example. I’ll be running Stockfish in the Chess Analysis app on android store.When we look at this position (with Black to move) we see the tempting Rook on f1 which is attacked by Black’s Bishop. Would taking the Rook be a good idea?Let’s fire up Stockfish and see what it thinks!Obviously, different programs will display chess engine analysis in different ways. Several pieces.

So I am using Fritz 17, its a bit tricky to use, I am using it to play against multiple engines easily, however the reality is not so easily have I done this right because there is not much indication that is what engine is running inside fritz when I start a new game:Step 1:I click on classic menu:Step 2:Not going to explain how to install another engine as its relatively easy to do but the screenshot below just shows the engines I have installed:Step 4:Here I made sure stockfish is the main engine being used:then I select it in the menu that pops up then click ok:I can now see that the engine is some sort of implemented in the main windowsStep 5:To start the new game you would think you click 'New Game' in the 'Home' menu at the top but I found this does nothing. Instead you have to click 'Levels' sub menu then choose an option here, I chose long game for 15 | 10 game.Next DON'T click OK click start game!I then begin playing a game against an engine as per below screenshot and as per earlier one the engine no longer says stopped it says stockfish, it also does not allow me to click the blue play button, no other indication anywhere comes up saying what engine I am now playing against.So my main question is:Is this actually playing against stockfish engine now or is it playing against fritz by some sort of default? Note the computer is playing against me fine with no issues.Also does anyone know if its possible to load custom chess pieces into fritz 17? I haven't used Fritz in many years, so I have no specific input. But, it looks like it's running Stockfish, because I can see the NNUE info. But can't you just look at the Windows task manager when the engine is running to find out the engine's name? duntcare wrote: what the heck is fritz basically I wanted something that plays against computer engines well, and this was the best GUI I could find after trying many free ones which were over the top with configuration when all I wanted to do was play chess, this even has a one game button play in easy mode which is perfect for beginners, not badly priced either, good if you want endless beginner level matches against decent engines, I am not always online either.
