Happy Holidays 2016

20161121-h22016.jpeg

The Checker Maven wishes all of our readers the happiest of holiday seasons. Regardless what holiday you might celebrate or how you might celebrate it, we hope this time of year brings you happiness and contentment.

During the holidays perhaps you have a little more free time, but even if you're busier than can be, one can always make time for some checkers. Today we present a study by that renowned player and author, the late Ken Grover; it's quite interesting and should give you plenty of holiday checker enjoyment.

Coffee and Cake, 2016

20161114-cc16-1.jpg

A bit of a holiday season tradition at The Checker Maven has been the presentation of a "coffee and cake" problem. This is the sort of problem that you show to your checker friends and bet them coffee and cake that they can't solve it.

We think this year we have one that will put you in the winner's circle and garner you a nice Saturday afternoon treat at your local café or coffee shop. Let's have a look.

You might initially ask, what's the difficulty? Are those Checker Maven people asking me to just give away some coffee and cake? But when you take a closer look, you'll see that White is mighty short of options. Maybe your friends won't get their coffee and cake so easily after all.

Now, it's only fair for you to try to solve this one first, before you spring it on your unsuspecting friends, don't you agree? So give it your all, and then click on Read More to see the solution.20050904-symbol.gif

Does Cress Make You Well?

20161003-cresswell.jpg

All over the internet and in the foodie and gourmet magazines, you can read about the many and wondrous benefits of watercress. Whether you put it in your salad or use it as a garnish, you're promised untold health benefits, with the idea that cress can indeed make you well.

Of course that leads us to a horrible pun, as we present a position that arose in a game between classic checkerists E. E. Cresswell and J. Wyllie. The problem dates back around 80 years and is our current Checker School entry.

12 Years

20161114-12th.jpg

Today The Checker Maven completes a dozen years of no-fail weekly publication, something we modestly believe is a significant accomplishment. We hope we've being doing our share in promoting the great game of checkers, and we do hope to be able to continue publishing for at least a few more years.

Someone who has contributed immensely to our game is Richard Pask, and to celebrate the "12" theme, we're taking a position that arises from Ballot 12 in his upcoming book, Complete Checkers. (It will be published by us most likely in spring 2017.)

Black has just blundered with 2-6 instead of the "star" move given in the Complete Checkers text, 17-22. How does White bring home the win? We suppose you ought to get 12 minutes to solve it, or 12 attempts, or something of the sort, but just do the best you can.

Thanksgiving Weekend 2016

20161010-weekend.jpg

We've always written about how we love the Thanksgiving holiday, a holiday that unites everyone. No matter what your race, religion, color, or political leanings, giving thanks is an American tradition that we can all support.

On this wonderful weekend we usually try to feature a problem from a great American composer or great American players. Today we'll look at a position that arose in a match game between two of the all-time greats, Walter Hellman and Maurice Chamblee.

A New Approach

20161010-oldnew.jpg

We often look for a new approach, a new way to do things. Sometimes that new way is better, sometimes not; and sometimes, it doesn't really make any difference. Is it an improved way or just another way? The answer is not always clear.

In today's installment from Willie Ryan's Tricks Traps & Shots of the Checkerboard, we continue looking at situations arising from the Kelso opening. Here's the run-up, without additional commentary.

10-15 22-18 15x22 25x18 6-10 18-14 10x17 21x14 9x18 23x14 1-6 29-25 12-16 26-23 16-19 24x15 11x18 28-24 8-11 24-19 4-8 31-26 6-9 19-15 11-16.

White to Play and Draw
W:W32,30,27,26,25,23,15,14:B18,16,9,8,7,5,3,2.

To make this a little easier (as the ensuing play is complex), we'll note right away that Teschelheit's classic Master Play gives a line with 15-10 for White to draw. Willie says he has something new, and gives 26-22 as the only move to draw. And so we simply pose the question: Who is correct? Willie, Teschelheit, both, or neither?

We urge you to explore the play for a while, and then take the old approach of clicking on Read More to see the different lines of play and the answer to our question.20050904-symbol.gif

And The Winner Is ...

20160926-winneris.jpg

This column will appear just after the U.S. Presidential election, but the time of writing (eight weeks in advance of publication), the polls made it too close to call, so we can't even guess who won.

But that lead us to the idea of publishing one of those highly irritating "What Result?" problems (but not even close to matching the irritation caused by the just-concluded political season).

Get Out and Vote

20160918-hilhead.png20160918-donh.png

In the United States, the Tuesday after this column appears is election day and Hillary and Donald are going head to head with the White House as the prize. We're writing this column some weeks in advance, so we don't know the current state of the polls, but we can safely say that this is the most, um, unique presidential election in many a year.

We urge you to get out and vote for the candidates of your choice. The right to vote is also a responsibility. Please do cast your ballot as your conscience dictates.

In checkers, going "head to head" over the board can also be quite a contest, although even as checker enthusiasts we have to admit that the stakes are somewhat lower, thankfully, than those in a Presidential election. No polls, no talking heads doing endless analysis of incredibly fine points, and, hopefully, no rancor, but instead just the enjoyment of the game.

Here's an actual "head to head" game, played long ago by Berry Mitchell and Chas. Hefter. (The actual players are not depicted below.)

2. 8-11 22-17
3. 4-8 17-13
4. 15-18 24-20
5. 10-15

11-15 is better; White now gets an edge.


5. ... 19-10
6. 7-14

6-15 may be the better choice of jumps.

Loses. 2-7 is correct.

Checker Cruncher

20161003-crunchit.jpg

Checker Cruncher is a new website under development by Brooks Thomas, and it's the first online checker tactics trainer to make an appearance.

While there's still some work to do, the site is eminently usable right now, and we found it rather impressive. We've made many repeat visits. A subscription model is contemplated for the future, but at the moment the site is completely free.

We asked Mr. Thomas to answer a few questions for us, and he graciously took the time to provide detailed responses.

20161003-cc-logo-full.png

1. So what's Checker Cruncher (CC) and what can we expect to find there?

Checker Cruncher is a web application designed to help people improve all aspects of their game and have fun doing it. The heart of the site is a large number of automatically generated tactics puzzles. Both players and puzzles get Elo ratings so beginners will be given easier problems while experts will be given more severe challenges. Other learning tools are also available such as a searchable database of expert games and an opening explorer to look at win rates and best moves. The puzzles are better for tactics and end games while the database is more for openings and strategy. Lastly, there is a forum for giving feedback and asking questions. More is coming as it's built.

All the puzzles come from real games where one player had the opportunity to win. Maybe that player found it and maybe they didn't but the engine claims the opportunity was there. Your task is to exploit said opportunity to the fullest. Some puzzles are as simple as promoting a king or choosing the better capture. Others are 20+ moves deep with zero margin for error. Each is a bite sized piece of practice for both the speed and accuracy of your calculation which is critical to avoid blunders and pounce on your opponent's mistakes. After each attempt you can check out the game the puzzle came from or look to the computer analysis for the answer. As of September, 2016, the puzzles are selected randomly because the ratings have not yet stabilized. As the player and puzzle count grows and the puzzles get sorted by difficulty I'll implement the smarter problem selection.

20160927-idea.png

2. What gave you the idea for CC?

I got the idea for Checker Cruncher from a friend at the coworking space where I work. I was playing a game of checkers over lunch and lamenting the lack of a checkers version of ChessTempo when he asked, "Why don't you build it?" At the time I was making a mobile app about billiards that I didn't have much faith in. Over the next few days it become obvious to me that Checker Cruncher was going to be both more fun to build and more likely to succeed. I knew I was on to something when I started getting distracted from building the site by practicing checkers on the site. Since then I've had more ideas then time to implement them.

20160927-clock.jpg

3. How long have you been working on it?

I started work almost exactly two years ago. I had never built a website before so HTML, CSS, and Javascript were almost entirely new to me. I actually started by doing Michael Hartl's tutorial for Ruby on Rails. Like many projects; if I knew then what I know now it would be long done. I've come a long way since then, both in programing and checkers abilities.

20160927-future.jpg

4. How do you see the site developing in the future?

I've got a huge list of features I want to add, I don't think I'll ever run out of ideas. I'd like to see a smarter problem generator, a larger game database, puzzle comments, tags, and share buttons, leaders boards, achievements, end game tutorials, live play, etc. I'm only one person so none of these are coming soon but if the site gets traction and enough users to pay for the hosting costs I'll keep adding features. Who knows where it might go?

In the near term I'm working on improving the site experience on mobile devices. It's not quite ready for phones but it's close. The smarter problem generator is also a big priority. I'd like the next batch of puzzles to be more consistent with where they start and end. It should also create fewer puzzles that have many winning moves. In the mean time, if you bump into a puzzle you don't like point it out on the forums. I can disable it and add it in my test cases.

5. Tell us a little about yourself (age, background, education, interest in checkers, location, profession, whatever you wish).

I'm 31 years old, living in Philadelphia. I got my degree in Computer Science at the University of Rochester in NY and have been a professional programmer since. Most of my experience is in windows desktop applications. Outside of work I've always had an interest in games and game theory. A little before I started Checker Cruncher I started playing chess more seriously and I'm now a 1700 rated player which I'm quite proud of. When I get the chance I also enjoy hiking and mountain climbing with my lovely wife Amanda.

I had no idea checkers was even an interesting game until reading about Chinook in One Jump Ahead. That was probably five years ago. I downloaded Martin Fierz's CheckerBoard and of course the engine Cake stomped on me so badly I didn't understand why. But I loved the simplicity of the rules vs the monstrous difficulty of the play. So I bought some pieces and started playing with whoever was willing. Now I play primarily with my friends and against my phone. I've thought about playing online but haven't really broken into it yet.

20160927-training.jpg

6. Do you think CC will become a major resource for checker training? Is that your long-term goal or hope?

Yes I hope so. I know it already works great for beginners. A few friends and I have been testing it and we've improved dramatically. Even very strong chess players have to practice tactics regularly, I think checkers must be similar. If it gets a healthy user base and good feedback I think Checker Cruncher could be a tremendous tool.

20160927-revival.jpg

7. What do you see as the future of English checkers? Is it bright or not so bright? Do you think checkers might some day see a revival?

Lots of work needs to be done of course but I think the future of checkers is very promising. One of the major reasons I play chess and checkers instead of Counter Strike and League of Legends is accessibility. Checkers has been around for centuries, it's one of only a handful of games you can play with both your grandparents and your grand kids. It's not going anywhere. Moreover I think more people are playing checkers now than ever before. The checkers phone apps have millions of downloads. People may be playing casually, primarily against their phones, or even without forced capture. But they play and if more serious players and organizations can reach and educate them I see no reason why checkers can't be a large and thriving community.

20160927-advice.jpg

8. Any advice for the aspiring checkerist and/or user of your site?

For the aspiring checkerist:

Play! Play with whoever is interested, kids, parents, coworkers. Checkers is the perfect game over a lunch break. But do warn your opponents about forced capture; at least where I am very few people know about that rule.

If you're playing against your phone or another computer turn the difficulty up to where you win or draw a little more than half the time. You should win often enough that you don't get frustrated but lose often enough to learn to be careful. As you improve, turn the difficulty up again.

For the tactics problems:

Like when you're playing over the board don't try to guess the answer. Take your time, spend five minutes thinking and try to see the whole solution before you make the first move.

20160927-lastword.png

9. Anything else you wish to say or add?

Please participate in the forums, feedback of all kinds is deeply appreciated! This is especially true for intermediate and advanced players, I'm working from my chess experience about what works, but checkers is a different game. For instance I'd love help building a list of favorite puzzles. My favorite so far is number 127.
