A little chess experiment...

by Andrew

I have composed a couple of problems to help you test your decision making and creative thinking capacities in chess. To give myself the best chance of avoiding people hating me following this exercise, I will advise you to take a very close look at the initial position before you make your first move. Good luck!


                                  Position 1: White to play, mate in 20 moves or less




If you were able to solve this, well done. Your solution may resemble somewhat one of the following lines:



If you weren't able to solve it, was it too long? Too hard? Too boring?

Okay, I understand; try this one instead.

Position 2: White to play, mate in 1


Yes, I have given you the same position--only with a different stipulation. Well, I did say 20 moves or less.

Probably you have found the solution by now, but let us consider for the moment how this position could have arisen. What was Black's last move? For instance, the queen could not have moved last as it already would have been giving check; similarly for the light-squared bishop and d7, and for the e- and g- pawns if they had been on e6 and g6 respectively. The d6 pawn could not have moved on the last turn given the light-squared bishop has somehow made it out already. And no black piece could have moved from a square that with White to move is currently occupied by a white piece.

(By the way, this position is possible: We can assume that prior to this White had played either b6 or c6, and Black had been oscillating with knight or light-squared bishop.)

So, a close inspection reveals that, in fact Black's only possible move prior to this position was  0...g7-g5, upon which, in accordance with the en passant rule, we are allowed to play the move 1.hxg6 checkmate.



Of course it was a bit of a trick puzzle, and perhaps a few readers/solvers dislike me right now for feeling I have wasted their time, but I think it teaches an important principle: that it can be very hard to see what you are not looking for. Maybe you began by seeing the number 20 and expecting the problem to be a very long one, thereby neglecting to appraise the initial position with much scrutiny or lateral thinking. I reckon if I had presented the first problem as "mate in 1" it would have been a very different story. Our expectations and assumptions inform our judgments and the way we view the world all the time without us realising it.

To be creative and heighten your ability to see different possibilities in chess it is important to be willing to identify and question what you think you know, to be open to receiving new information, and not to cast judgment before judgment is due. This, I believe, is the sort of perspective one should try to adopt if one wants to develop and maintain a free-thinking and creative mind, for chess and for life.

I hope, dear reader, that I have not perturbed too severely your faith in my trustworthiness and that you will come back to read my future posts. Next time I will try not to be quite so mean. :)

More fun with pins

by Andrew

This time the theme is answering a checkmate (or rather an almost-checkmate) with a checkmate. The first three are pretty simple, while the last has many variations and may require a bit of effort (but hopefully it is worth it!).

Australian Juniors Nostalgia

by Junta

I'm currently working as a coach for some ACT players at the 2015 Australian Junior Chess Championships in Canberra (Results here) - I played seven Australian Juniors from 2002-2008, and I still remember the excitement from the 2002 edition as a 10 year old, playing interstate for the first time. 13 years later, I'm coaching 10 year olds playing their first Aus Juniors, and I couldn't help but check out my first ever Aus Juniors game. Not a bad game considering the rating!

Yusupov: It's a Question of Probability

by Junta

A couple of excerpts from a recent interview (originally in Russian for ChessPro) with former world #3 player, Artur Yusupov, which left an impression on me:

Why sport and fitness are important

Every element is important – the pure chess element as well, of course, but not only. It’s a case of increasing the probability of a good performance, which is something many people fail to understand. They think, “Ah! Today I didn’t play any sport but I still won, so I don’t need it”. Or the opposite. “I played sport but lost the game”. And people don’t realise that it’s a question of probability. You can do everything correctly and increase the probability of winning by some percentage, but it’s never going to be 100%. Surprises can’t be ruled out. You can, of course, do everything correctly and lose, or everything wrongly and win, but the person who does everything correctly will win more often. You can’t argue with the statistics, and that’s the big difference. Those who fail to follow a sporting regime can be very talented and win individual events, but over a long period of time they’ll do worse than the professionals, and that’s the whole point. When I went on all my runs before important tournaments I thought: “I’ll suffer now, but in the tournament I’ll pick up an extra half point!

On how wins aren't always the result of our brilliant play

A win is always the “achievement” of our opponents. I understood that very well when analysing my old games. I’d naively thought that I outplayed my opponents, but a closer analysis with the help of the computer showed: nothing of the sort! Basically my opponents had even understood the position better than I did and they played well (laughs), but at some decisive moment, perhaps, they lacked energy. They committed a bad mistake which altered the logical course of the game. Analysis showed a totally different picture. So you always win due to the mistakes of the guy sitting opposite. It’s simply not possible otherwise.

Anti-Hassberg and Ellerman Blend Themes

by Junta

Pinning and unpinning...lots of pinning and unpinning in two themes from the Encyclopedia of Chess Problems (Chess Informant), a merry book for chess problem lovers which I came across in the chess collection of the State Library of Victoria.





520 pages with 1726 problems!

Qatar Masters Open

By Moulthun Ly

Right now there is a super strong open taking place in Qatar. It has a 2200+ rating cutoff and features an abundance of top GM's over 2600. Often, while watching elite events, there may be long waiting periods while the players decide on a move, due to the small number of games. However, with so many interesting games going on that has not yet been an occurrence.

In fact, several months ago, I had the intention of playing this event but later decided not to for various reasons. This wasn't specific to this situation - it has applied on and off the board. I did feel a small sense of regret for not playing when it was possible, but this is nothing new and happens almost all the time during my games. I will choose a line only to have a change of heart shortly after.

Even at top level this can happen, for instance during the recent World Championship match when Anand missed his big winning opportunity in a crucial game. I wonder for how long that must have affected his state of mind. The best thing I have learnt to do, is take everything "move by move" and "game by game". This can happen to anyone so unless we are able to adjust, the rest of our games/tournament is pointless. So I suggest you do not overlook this, always keep looking forward.

Costeff Promotion Study

by Junta

"...When I think of an abstract idea, I manage with no board and pieces. But after that, I use the board, and every once in a while I check things with the computer...This tool helps me to save earlier versions, so you can see how the idea has evolved. For some of my studies I have in my files 100 different versions, and there is at least an equal number of versions that I do not bother to save."
- Gady Costeff,
 in an interview from the book The Grandmaster's Mind (2004)

I was compiling six studies for my column in the 50 Moves Magazine (December issue will be out on Monday!), and came across some brilliant pieces which didn't make the cut - below is just one example. The theme for this issue was promotion. The solution is playable in a game viewer below the diagram, so don't scroll down if you want to solve it. By the way, the difficulty is super-duper high so unless you're a problem aficionado (even then!), it's going to be a fatefully tough one to crack. Please enjoy the solution (and all of the beautiful variations) either way!

White to play and win


Gady Costeff, 3rd Place
EBUR {ARVES}, 2004







While I was compiling studies for the issue, I went through all of Costeff and Gurgenidze's published studies (for which the stipulation was White to play and win) - they're definitely two of my favourite composers.

Chess Reading List

By Moulthun Ly

I am often asked by people to recommend various chess books. 
Therefore, I have gone through my collection and taken note of 
those I felt helped my chess improvement or were particularly interesting. 
Of course there are many others which I may not have had a chance to read. 

I have avoided listing any opening books for now as they are specific to players
interests. However, I may also go through and list these at a later time
as there are some great books being released. 

They are roughly grouped by various rating levels in which they were read.
However, many can be enjoy by players of all levels.

Happy Chess Reading!

Vikings Weekender 2014 Open Section - Pictures

by Junta

Canberra's third biggest annual tournament (after the Doeberl Cup in April and ANU Open in July) is the Vikings Weekender held in November. This year the Open section saw 21 players and the Minor section 38 players, a healthy turnout.

There were six players rated over 2000 in the Open section.

A truly Aussie weekender in its toughness of having to play four games of 60 10 on the Saturday (10:30am-10pm), followed by three on Sunday.

6/7 - The winner was Moulthun who conceded draws with Jason and Anton. As usual he played games in his correct and positional style, not giving his opponents any chances, only being in real danger in our Round 4 encounter.

5.5/7 - 2nd was Anton who surprisingly conceded a draw to rapidly improving ACT junior Dillon Hathiramani (rated under 1700 - a great upset!) in Round 1, and otherwise just conceded draws with Moulthun and myself on the second day. It was nice to catch up with him after we played together in the Politiken Cup and Olympiad back in July and August.

5/7 - I came 3rd after losing to Moulthun in a close game in Round 4, and drawing with Jason and Anton on Day 2. I was happy with most of my games after a 3-month break from playing.

4.5/7 - three local players shared 4th-6th, with special mention going to Dillon - after drawing with Anton in Round 1, he did not slow down and scored 4.5/7 (PR 2033) against opposition averaging 1931 - his expected score was 1.75! He is coached by local trainer Peter Simpson (who has also been the trainer of Olympian Emma Guo, and has been helping many Canberra juniors over the years). 

Jason Hu was one of the players on 4/7 - he has recently been performing strongly, and in this tournament he managed to hold a draw against Moulthun, took a half-point bye in Round 4 due to illness, drew with me in Round 5 when he had a rather simple mate in the final position (instead giving perpetual check), and lost to Anton from a position of strength in Round 6. In fact, his biggest test may have been the drive to Canberra - on his last two occasions, in pretty much the same area on his way from Sydney he had crashed into kangaroos who had 'come out of nowhere'.
Dillon is on his right
Local junior Michael Kethro celebrated his 15th birthday on Day 2 of the tournament. Apart from Jason, he was the only player to play against the three IMs in the field.
