A few end of season things to take note of:

  2. Everyone will need to fill out a new registration for season 7. For those who want to compete in season 7, the moderators have set up a mailing list. Please fill out the google form ( if you want us to email you when season 7 registration opens (in addition to the regular announcements on slack/reddit).
  3. Please send any fun stats/awards you want to be highlighted in the Season 6 End of Season Awards/Stats page to @tnan123. See the previous pages of awards for an idea: Season 5 and Season 4 page Who wins this year's Giri Award, Marathon Man, Accuracy King and much more?!
  4. We will open nominations for season 6's best games. Nominations will be done via the website. Each player can only nominate 1 game. When you have a game in mind send @chesster a DM with nomination 45 and you will be given a link to enter your nomination. The link will expire after 1 hour.

In Lonewolf, there are 4 rounds remaining with over 100 participants still playing. @DonJohn retains the sole lead with an amazing performance of 6.5/7 points. @Groundhopping and @ghdef457 are the closest chasers with 6/7 points.

In Blitz-battle we had our first repeat winner in the strongest field yet (including FM @lovlas, and past winners: @Alex_1987 and @FelixNL). Congratulations to @Abhy0024 for his 2nd Blitz-battle win.

Finally, here's an update on the ladder league as well: @Alex_slow currently holds the top spot. @theino has been the biggest mover. He only recently joined but has made his way up the entire ladder into 5th place! If you are interested in participating in ladder join #ladder on slack.

Coaches Corner

This is a new feature in the Ledger and hopefully other chess coaches in our community will find something to contribute.

Here’s a tip on chess calculation by FM @lovlas

Chess calculation technique suitable for every age and level

You might have heard of the common phrase: ”Patzer sees a check gives a check”. It’s used to describe players at beginner level who gives a check without any thought. You will usually notice this behaviour with kids, who just learned the rules. What if I told you it isn’t necessarily a bad approach?
I certainly don’t mean that you should always give a check, but rather that you should always look at the most forcing moves first. The most forcing move is the one that leaves your opponent with the least options. If this move turns out to be rubbish, we look at the second most forcing move, and so on.
Take this position for example:

Black has four moves that leave white with only one response: Qxh2+, Qg2+, Qf1+ and Qxf3+. We can easily conclude that the first three simply blunders a queen. That leaves Qxf3+. After a quick calculation, we can conclude that white is getting mated after 2.Bxf3 Bxf3#.
Next one:

A less informed player would probably start calculating 1.Qh8+, but we know better. The most forcing move is 1.Qxf7+, which leaves black with only one option Rxf7. After doing the math we see that 2.Ng6+ Kg8 3.Rg8# is mate.

This approach to chess calculation allows you and your student to find the position's killing blow while saving time. It can also be applied to any position and will usually give you the answer, especially at lower levels. It’s perfect for teaching your students how to calculate, no matter their level.

For additional reading I would highly recommend Forcing Chess Moves by Charles Hertan.

Chess For You


Among a great many other things that chess teaches you is to control the initial excitement you feel when you see something that looks good. It trains you to think before grabbing, and to think just as objectively when you’re in trouble. When you’re making a film you have to make most of your decisions on the run, and there is a tendency to always shoot from the hip. It takes more discipline than you might imagine to think, even for thirty seconds, in the noisy, confusing, high-pressure atmosphere of a film set, but a few seconds’ thought can often prevent a serious mistake being made about something that looks good at first glance. With respect to films, chess is more useful preventing you from making mistakes than giving you ideas. Ideas come spontaneously and the discipline required to evaluate and put them to use tends to be the real work.

—Stanley Kubrick, in a September 1968 interview
with Eric Nordern for Playboy magazine


Chess Puzzle

From a round 8 game in 45+45 on board 6: @thebishopschaplain vs @hive. Black just played Qd7. White to move. This one might seem easy at first, but think about black's response to the obvious move you might be thinking about. 

For the answer see gamelink.
