US Champ R4: Peace

4/5/2015 – It was not the best played round of chess, and the excitement level went down just a little bit. The open section had six draws, some more exciting than others. The anticipated match up between So and Nakamura finished in a draw after Nakamura blundered a pawn, but was able to hold the draw. Meanwhile the action in the Women's was very up and down to say the least.

WWch Final G2: Muzychuk takes lead

4/4/2015 – The second game probably caused no end of heart attacks from fans of both players. The nerves, compounded by more than two weeks of non-stop play without break, began to show, and after a highly theoretical Ruy Lopez Breyer, Muzychuk set up a huge attack, while missing winner after winner. Would Pogonina regroup and defend, or would Muzychuk finally cash in? It was drama to the end.

US Champ R3: Sevian defeats Top Ten

4/3/2015 – The round was wild for all sides, and all boards, but the news of the round, without question, was 14-year-old Samuel Sevian's defeat of World no.8 Wesley So, who resigned just short of getting mated. This was hardly the only surprise as Nakamura let Kamsky escape after squeezing him the entire game, while Irina Krush was on the wrong side of a massive attack by Paikidze. Nakamura-So tomorrow!

Google Tooth?? You must be kidding!

4/3/2015 – Yep, the Google X lab project to replace human molars with electronic devices (and use them to play 3000+ level chess) was the April 1st hoax. Pure invention – well, as far as we know. So we are left with having to believe in a possible refutation to the English Opening and that the minor planet Vishyanand is circling the sun. Perfectly true – in fact you can name a planet yourself!

Clear case

4/3/2015 – Tactics can seem deceptively simple, particularly when seeing an engine analysing grandmaster games. Strange, however, how difficult it is to find the right move and to calculate variations properly when playing yourself. It is easier if you solve tactical puzzles regularly. In the ChessBase Magazine and his tactics column Oliver Reeh helps you to do so.

WWch Final G1: At last

4/3/2015 – After over two weeks of relentless competition, the final match has arrived. It is hard to imagine the toll this has had on the players, since this is not like a two week tournament, each two games determined whether they would stay or go home. At last, only two warriors still stand, and both went through their own trials of fire. Report, game and player impressions.

U.S. Champ R2: Favorites perfect

4/3/2015 – One did with a very clean game, the other with a bit of luck. Hikaru Nakamura cleanly wiped Varuzhan Akobian off the board after Akobian sacrificed a pawn, got no compensation and lost. Wesley So had a win against Sam Shankland, missed it, and a huge blunder by White in that game gave So the win. The best game of the day, though, without a doubt, was played in the Women's section.

Karpos Open under way in Macedonia

4/2/2015 – With the so many events running, it would be easy to overlook the lovely Karpos Open, currently being held in Skopje, Macedonia, but it shouldn't considering the excellent conditions, held in a five-star hotel, and generous prize fund that has attracted 98 titled players of whom 33 are GMs ready to fight for their spot in the sun. An illustrated report by Diana Mihajlova

Interview with Boris Gelfand

4/2/2015 – Since the 1980s Boris Gelfand has been one of the world's best players.

In a 33-minute interview with Tania Kisilevski from the Russian TV station ETV he now revealed interesting things about his life as a chess professional.

Master Class - José Raúl Capablanca

4/2/2015 – How does one dissect a player such as José Raúl Capablanca, considered one of the greatest talents to ever live, and described as a "chess machine". Three grandmasters do exactly that, unveiling surprises about the champion's play. Add to that tons of training questions, plus hundreds of his games analyzed by Lasker, Alekhine and Capablanca himself, and you have a DVD you must not miss!

U.S. Champ R1: Comedy of Errors

4/2/2015 – At least you can say the games were exciting! Many of the games, in both sections, were decided by blunders or big mistakes. Nakamura won thanks to a blunder by Holt, So because of a blunder by Naroditsky, Onischuk blundered a pawn but managed to hold a draw, Robson beat Troff also because of a blunder. In the Women's section, something very similar happened.

Google Tooth – the latest in wearables

4/1/2015 – Everyone is doing it: after the iPhone and Android we are now confronted with Google Glass, Apple Watch, the Pebble. Computers are getting smaller and can be built to accompany you wherever you go. Now Google X, the semi-secret facility run by the search giant, is working on a dental computer. Why do we tell you this? Because Google Tooth comes bundled with a chess app.

April 2015 ratings: Youth on the rise

4/1/2015 – After an incredibly busy couple of months, the April ratings list was a fairly quiet one for the top players for the most part. It isn't that the players were all on vacation, hardly, considering David Navara logged in 29 games in just one month. On the other hand, the juniors and girls saw several incredible results, including the rise of 10-year-old Abdutassorov, now rated 2465.

Minor planet named after chess player

4/1/2015 – In 1988 an asteroid or minor planet was discovered, but remained unnamed for more than ten years. Michael Rudenko, committee member of the Minor Planet Center, a chess buff with a Playchess account, decided it was appropriate to name the object after Viswanathan Anand, himself an astronomy buff. It is now officially known as '(4538) Vishyanand'.

The Bremer Counter Attack

4/1/2015 – Can an opening be solved, can a line be thoroughly refuted and unplayable? How about the Anglo Scandinavian (1.c4 d5) being used to bust the English Opening?

WWch Semis TB: Oh the humanity!

3/31/2015 – The Women World Championship has been one of the most exciting on record, with drama, tension, front runners, and comebacks, and plain old fighting chess.

WWch Semis G2: the queen of must-wins

3/31/2015 – Three times Natalia Pogonina was faced with a must-win situation, a draw would see her in the spectators side of the cordoned area, and three times she pulled it off to press her claim to the Women World Championship. Harika Dronavalli drew her second game with Mariya Muzychuk, so both semifinals will be decided by tiebreaks. Report and interview with Pogonina.

Hawaii GM Challenge (Part 2/2)

3/30/2015 – The string of activities in Hawaii left the players with almost no time to do anything. Once the GM Challenge kicked off, it was clear that Waikiki Beach would have to wait until the tournament ended.

Aeroflot R3: Brilliancies

3/30/2015 – The news of the day is that one player was able to move to a perfect 3.0/3: Krishnan Sasikirian from India showed excellent handling of the Black side of the Scotch to be the only player remaining with a perfect score.

WWch Semis G1: Cramling scores first
