Slim pickings

Unlike round robins, swisses are normally a feast of good and bad chess, where every game is important (except maybe the last round), and players bounce up and down the standings with great regularity. Unless of course it is an elite swiss, in which case, every treads warily, keeping a close eye on all the games to make sure no one is getting too far ahead.
The Mallorca Grand Prix is providing slim pickings for anyone who likes the score table to contain lots of 1's an 0's. Not to disparage a good hard fought draw, but with over 60% of the games ending that way, not every draw is a result of players battling till exhaustion.
Of the decisive games, there have been a few that have jumped out at me. The one I've chosen for this post was Svidler's win over Hammer. Apart from the rarity of seeing 'actual mate on the physical chessboard', the fact the White king gets hacked on the kingside in a sicilian also adds to its attractiveness.

Happy Birthday Capa

Toady is the 129th anniversary of the birth of Jose Raul Capablanca. Generally considered one of the "Top 5" World Champions (along with Alekhine, Fischer, Karpov and Kasparov) he started as a child prodigy, before  become a full time player at the age of 20. He won the World Championship in 1921 and then lost it to Alekhine in 1927. He never had another chance to play for the title, and died at the relatively young age of 53.
Capablanca was considered a positional player, focusing on piece placement, and improving his position through 'petite combinations'. This enable him to outplay his contemporaries, although he met his match against Alexander Alekhine. His style influenced the next generation of chess players, especially Bobby Fischer and Anatoly Karpov.
Even at the end of his career he was still able to target a weakness and build an entire game around it. In the game below (his final tournament game), he isolates Black's c pawn on move 9 and then builds up pressure on it. Black is forced to make positional concessions to defend it, and eventually ends up in a lost position.

Chess and Beer

Due to a number of other activities I haven't been running Street Chess recently. Today was my first time back since the start of October, and on my return, I received a pleasant reward.
One of the event sponsors, King O'Malley's Bar, was running a 'design your own beer label' promotion, in conjunction with Adobe. This was too good an opportunity to pass up, so I created a very limited run of "Street Chess Beer". So limited that only 4 bottles were made. Three were given away as prizes(although not to the tournament winner Sankeertan Badrinarayan as he isn't quite 18), and one I kept myself (although I only have the bottle, as my 19 year old son consumed the contents).
A couple of people wondered If i had brewed the beer myself (No), but maybe this is something worth looking at in the future.
"Drink & play responsibly"

FIDE Grand Prix resumes

The final event of the 2017 FIDE Grand Prix series begins today in Mallorca, Spain. While the GP series tends to get lost among the other big events on the calendar (GCT, World Cup plus big opens in Iceland, UK and Isle of Man), it still helps determine the qualifiers for next years Candidates Tournament. The top two finishers (who did not qualify through the World Cup) qualify for the Candidates, and at this stage there are 4 players still in with a chance. 
Mamedyarov and Grischuk currently hold down the top two places, but have already played there 3 events (each player plays 3 of the 4 GP tournaments). As a result, there is still a chance they can be overtaken by Vachier-Lagrave and Radjabov. Ding Liren is also in the leading group but has already qualified (via the World Cup).
The official site for the tournament is https://worldchess.com/gp2017/ I'm pretty sure there is no free coverage from this site (it is a pay for view event), and I'm not seeing any of the other major websites with links to coverage (although I may have missed them). Whether this is due to legal reasons or indifference (or indifference caused by legal reasons) I do not know.

The injustice of it all

While wearing my ICCF Tournament Directors hat, I discovered something I had not previously been aware of. There are some Queen endings where two connected passed pawns aren't enough to win. This was drawn to my attention when a game in an event I was directing was drawn after one of the players made a tablebase claim (In Correspondence Chess a player can claim a draw or win if the position is assessed as such in a 6 piece or less tablebase). While the claim was perfectly valid I did feel a little sorry for the other player involved.
Even without the advantage of modern technology, the game may well have been drawn anyway, as it turns out there have been some precedents.  In 1985 Boris Spassky was defending exactly the same position against Zoltan Ribli and successfully held. Here is the game in question, with Black having a completely drawn potion by move 82.

Ooooopsss!

I've just caught wind of an unfortunate occurrence at the 2017 World Seniors. In the game between GM Rogelio Antonio and IM Alexander Reprintsev, the following miniature occurred. 1.e4 d5 2.exd Qxd5 3.Nc3 Qb5?? 1-0
In moving the queen to a5, Reprintsev placed it on b5 instead (or at least enough of it to matter), at which point it was able to be captured by bishop or knight (One report indeed had 4.Bxb5+ as being played, although this didn't appear in the online version I saw).
There is some argument that Antonio should have let the queen go to a5 as intended, and if I was White in these circumstances, I would have done so. On the other hand, if I was Black, I would have let the move stand, accepting the responsibility for my mistake. And finally, if I was an arbiter, I would almost certainly let the players sort it out among themselves (ie if neither player claimed a breach of the rules, I wouldn't go jumping in)

2017 Vikings Weekender - GM Anton Smirnov wins

GM Anton Smirnov has won the 2017 Vikings Weekender with a perfect 6/6. He had to face IM Andrew Brown in the first round of the day, and then 3rd seed Fred Litchfield. Winning both those games he then been Tim Pearce in the final round to finish the event on 100%.
IM Andrew Brown recovered from his loss to Smirnov to win his two remaining games to finish second on 5/6. However he was once again fortunate to survive some difficult positions, being in a lost position against Donato Mallari with seconds left on his clock, only to see Mallari overstep the time limit. Mallari at least had the consolation of finishing in equal third, along with Dillon Hathiramani and Angelito Camer.
Amol Kiran finished first in the Minor event on 5.5/6. Kiran (who finished equal first last year) drew with Athena Hatirmani in the final round to finish a point clear of Hathiramani and Lachlan Ho.
Despite the numbers being down 25% this year (65 last year, 48 this time), the organisers were able to pay out more than $3000 in prizes, due to the generous sponsorship of Tuggeranong Vikings Rugby Union Club, Street Chess and Jim Flood. The ACT Chess Association also provided financial and material support for the tournament, as did the Tuggeranong Chess Club, who hosted the event.
Full results as well as games from the top 4 boards of the open (for each round) can be found at http://tournaments.streetchess.net/vikings2017/
