In last week’s post we learned how to submit positions for analysis to the worldwide community of Fritz13 users. Each time you submit a position, it costs you a credit – which obviously leads to a followup question: how do you earn more credits? That’s the question we’ll answer today…
Earning credits doesn’t cost you anything, other than a little time. Maybe you’re going to spend a few hours away from the computer watching some football (or, if you’re like me, some futbol). Perhaps you’re going to spend some time with the family. And we all need to sleep sometime. It’s during these times, when using your computer isn’t a critical task, that you can best earn “Let’s Check” credits by analyzing positions submitted by other users. The best part is that the process is automatic; you don’t have to do a thing except click a couple of buttons to start the process.
We’ll begin by launching Fritz13 and clicking on the “Play Fritz” command in the splash screen. Next we’ll load the engine we want to “volunteer” for the analysis by either hitting F3 on the keyboard or clicking the “Change Main Engine” button in the “Engine menu” to get this dialogue:
…then selecting the engine we want from the scrolling list, and setting the hash table size and other parameters by clicking the “Advanced” button. You can use any engine for this purpose (as long as it will run in the Fritz13 interface, obviously).
After we’ve selected the engine, we’ll click the “Let’s Check” button to connect to the server:
Bear in mind that the current board position on your Fritz13 chessboard doesn’t matter; the “Let’s Check” server will soon be feeding positions to your computer for your chess engine to analyze. After your machine has made the connection to the server, you’ll see that the “Contribute engine” button is now available:
Clicking the “Contribute engine” button starts the process of analyzing positions submitted by other “Let’s Check” users. You can walk away at this point and come back at a later time to stop the process (by clicking the “Contribute engine” button a second time). But let’s look at the process in action…
When you click “Contribute engine” you’ll see an information box appear in the middle of your screen:
…which indicates that the Fritz13 software is waiting for a position to be sent from the server. After a position is received by your computer, you’ll see the information box change:
…to indicate that the first position has been received – you’ll also see the position on your Fritz13 chessboard switch to the position being analyzed.. The chess engine you’ve selected will analyze the position for several minutes, then the server will send another position for analysis:
When you contribute an engine to analyze other users’ submitted positions, the progress bar in the engine analysis pane gives an indication of how long the engine will analyze until another position is submitted:
The bar gradually turns green as the engine’s analysis of the current position nears completion.
This process will continue until you stop it by clicking the “Contribute engine” button a second time. When you stop the process, your total number of credits earned (that’s total, not just the number you earned in that particular analysis session) will be displayed in the scrolling informational pane:
You can later “spend” these credits to submit positions you choose to the “Let’s Check” community for their engines to analyze (“returning the favor” so to speak).
When I’ve said in blog posts and “how to” videos that Fritz13’s “Let’s Check” users are a worldwide community, that’s no exaggeration or mere hyperbole. Scores of chessplayers from around the world are helping each other out by analyzing chess positions and submitting their own interesting positions for analysis. So please keep in mind that you can use your own “computer downtime” to run this automatic analysis function, thus helping other players, and be rewarded in turn with credits which allow you to submit your own “knotty” positions for analysis (as we saw in the last post to this blog).
Have fun! – Steve Lopez
