Playing the back marker

You're cruising along, have a couple of wins under your belt, when you have to play someone at the tail end of the field (note, I'm talking about round robin events). Suddenly you have to make a choice. Do you (a) decide that the point is in the bag no matter what you do, and so play for the brilliancy, (b) play extra cautiously as you don't want to blow a sandshoe, or (c) ignore the scoreboard and play the position on the board?
Most people would say that (c) is the correct choice, but I suspect that in practice, the actual split may well be 40% a, 40% b and 20% c.
An extreme example of some choosing box A was Frank Marshall in the 1903 Monte Carlo tournament. Although he finished slightly below 50%, he decided to have some fun against possibly the most famous 'back marker' in tournament history. This was the event where Charles Paul Narcisse Moreau (known to chess history as Colonel Moreau) scored 0/26, losing all his games to the other 13 competitors. While Marshall was known for his attacking play, this game saw it taken to the extreme, playing a Muzio Gambit, offering two pieces within the first 8 moves. The unlucky Moreau was doing OK until move 16, where Bc6 turned out to be the losing move, as the pin down the d file resulted in material lose.

So much late night chess

Spring must be a popular time for chess events in the Northern Hemisphere as three big tournaments are running at the moment. In Germany the Grenke Classic sees Carlsen, Caruana, MVL, and Aronian battling in an 8 player round robin, while the accompanying Open has attracted a massive field. In Reykjavik the Open is underway, with 33 GM's in the 266 player field. And the Gashimov Memorial is just starting, with So, Kramnik, Karjakin and Adams in the 10 player field.
The best bit about all these events is that they are all being broadcast live on Chess24. This makes following the tournaments a little easier, as you can just jump from tournament to tournament, without having to jump from site to site. And if you are pacing yourself, the Gashimov Memorial starts mid evening Canberra time, Grenke at 11:30pm and Reykjavik a couple of hours later.

2017 O2C Doeberl Cup - An arbiters reflection

As the Tournament Director of the 2017 O2C Doeberl Cup I think the tournament ran very well. In fact one common comment from the arbiting team was how quickly it seemed to finish, which usually indicates there were no major issues (which there weren't).
This was especially noteworthy as the field of 280+ players was the second largest on record, and the venue was a little trickier to handle this year. here were a couple of reasons why the tournament ran well this year, first and foremost due to the growing experience of the organising team. I was able to hand off most of the routine tournament management to my fellow arbiters, while I concentrated on pairings and keeping the DGT boards broadcasting (Note to self: A new laptop next year!).
On the whole the players themselves were much better behaved this year, almost certainly as a result of decisions taken last year concerning serious misbehaviour. We still have to patiently explain the 'no mobile phones' in the playing hall to parents (and no, having them on silent is not an excuse), and some conversations were a bit loud, but the spectators were pretty good this year as well.
There were a couple of interesting incidents in the tournament, including a game in the Premier where a player accidentally captured his own piece (two minute penalty and he had to move the piece first touched). A few players are still confused about the time control, with one game seeing both players surf the 30s increment until move 70, not realising that an extra 30 minutes was added when one clock went to zero. Next year we may shift the Premier back to a straight 90m+30s, in part because of this confusion.
The level of withdrawals was thankfully low, with only a few forfeits (one of which was the organisers fault), and 'silent' withdrawals. Disappointingly the last round of the Premier had one player forfeit his game stating he was unwell, but this seemed to be a short term illness as he hung around to watch the complete round.
I'd like to thank the rest of the team for their work this year. Charles Zworestine (Premier), Alana Chibnall (Major), Lee Forace (Minor) and Miona Ikeda (Under 1200) put in an enormous number of hours to make the tournament a success, and I for one am very grateful for their efforts.

Oh No, another time waster

Blizzard have just released a free version of the original StarCraft, along with the expansion. It has been patched to fix any bugs that have been noticed over the last 8 years(!) and runs under all the Window releases (including 10). You can download it from the Blizzard site.

An arm-brain puzzle

Arm-Brain is a partnership variant where one player names a piece to be moved (eg King or Knight), while their partner decides which piece (if there is more than one) and the move to play. It is a fun game, although I find it very challenging. But not as challenging as the following puzzle.
While not quite 'Arm-Brain' the conditions of the puzzle are as follows: White starts with 1.e4 and can then tell Black the type of piece they can move (again, Knight or pawn etc). Black is free to make any move with the type of piece named (so if White says pawn, any pawn move will do). Can you find a Mate in 5 for White? (NB White can name a different piece for each Black move).
This challenge was set by GM Michal Krasenkow over dinner after the Doeberl Cup had finished. Tournament winner GM Surya Ganguly solved it in around 20 minutes, while I gave up after 10.

2017 O2C Doeberl Cup - Ganguly dominates

The 2017 O2C Doeberl Cup has finished with a dominating win for Indian GM Surya Ganguly. Going into the final round he led by a point over GM Michal Krasenkow, and a relatively short draw with GM Bartlomiej Heberla secured him outright first on 8/9. Krasenkow had a tougher game on board 2, but was able to hold off a strong attack by Fedja Zulfic to take outright second. GM Zong Yuan Zhao was the best of the local players, finishing in third place with 7/9.
Ganguly was clearly the dominant player of the tournament, beating Krasenkow in their decisive Round 5 games, and only conceding draws to Zhao and Heberla. Krasenkow also showed his strength, winning 7 games, and drawing with Zhao in round 7. Zhao should also be pleased with his performance, drawing with the top 2 seeds and finishing undefeated.
Further down FM Luis Chan had an excellent tournament, picking up the prize for the best Australian junior. Unrated Longfei Zhao (CHN) also did well, scoring 5/9 in his first international event.
The Major was won by Brendan Zou with 6/7, while the Minor saw Parunithan Ranganathan and Aiden Odenthal  share first prize on 6.5/7, having drawn with each other in round 4 and winning all their other games.

2017 O2C Doeberl Cup - Day 3

Day 3 of the 2017 O2C Doeberl Cup saw the top seeds continued domination. GM Surya Ganguly went to 5.5/6, with a win over GM Michal Krasenkow in the morning round, before a hard fought draw in round 6 against GM Zong Yuan Zhao. Krasenkow recovered from his round 5 loss to score a convincing win over IM Trevor Tao to finish the day on 5/6. GM Zong Yuan Zhao is also on 5/6 after his draw with Ganguly, and he and Krasenkow are due to play in round 7.
IM Gary Lane, IM James Morris, IM Junta Ikeda and English FM Brandon Clarke are just behind the leading group on 4.5, with Clarke in the frame for an IM norm, while good results for the other players could leave them with GM norm chances.
Last night saw the traditional Doeberl Cup Lightning, which attracted a field of 105 players. IM Junta Ikeda entered at the very last minute, and proceeded to dominate the tournament, starting with 8 straight wins before a final round draw secured an easy first place.
