    Performance-Enhancing Drugs in Chess?

    Maybe. Perhaps a reader with access to the journal article and a willingness to work through the material can attempt to assess the study's value, but based solely on what's in the first link the conclusion is dubious.

    These are the reported results: modafinil (sold as Alertec, Modavigil, and Provigil) improved players' performances by an average of 15%, while methylphenidate (sold as Ritalin) improved players' performance by 13%. Not to be missed: caffeine intake resulted in a 9% increase. (What exactly that means isn't spelled out: is it in terms of IPRs? Percentage scores in a player's results? Something else?)

    Was the methodology good? Is it ethical to ingest these substances (at least those which are prescription-only) for these purposes? Is it safe? These are all important questions to be asked before anyone considers taking modafinil and/or methylphenidate for performance-enhancing purposes, and as FIDE and national chess federations decide whether or not to ban such substances and test for them.

    There is an apparent problem with the study, however, and it's very odd that it is swept under the statistical rug - at least in the publicly available material. Apparently those taking either modafinil or methylphenidate played more slowly, and games lost on time were thrown out. Since tournament play always involves time controls, such an exclusion is an absurdity if the aim is to evaluate the effect on performance in competitive play.

    But maybe I'm missing something; if so, I count on my savvier readers to set me straight here.

    This Week's World Chess Column: Lu vs. Hansen from the Challengers Group at Wijk aan Zee

    It's not every day that a 2600-level GM loses with White in just 20 moves, especially without making an outright blunder, but that's just what happened in the round 10 game between Lu Shanglei and Eric Hansen in the Challengers Group in the Tata Steel Chess Tournament. For all the gory details, have a look here.

    So's Coach: Tukmakov

    For the last seven months or so, though apparently only on an occasional basis until recently, current world #3 Wesley So has been working with Ukranian GM and trainer Vladimir Tukmakov. Tukmakov had previous enjoyed a successful stint with Anish Giri; if he enjoys comparable results with So (obviously not a given, as So is starting from a higher rating and is a couple of years older than Giri was when he started working with Tukmakov) Carlsen's all-time rating record will be in danger. Regardless, So is in his quiet way becoming a bigger and bigger star practically by the month. Just a few months ago I thought that Fabiano Caruana was the clear early favorite for the next Candidates tournament; now, who knows?

    Gibraltar 2017 Underway

    The Tradewise Gibraltar Chess Festival (henceforth just "Gibraltar") has become increasingly popular and strong, and now it's a kind of super-open. World #2 Fabiano Caruana is the top name on the marquee, and then there are another 11 players over 2700, including Maxime Vachier-Lagrave, Hikaru Nakamura, Vassily Ivanchuk, Michael Adams, Peter Svidler, Veselin Topalov, and Boris Gelfand. There are some players in the upper 2600s as well, including several who have been over 2700 in the not too distant past.

    There were some upsets in round 1, and some games that should have finished in an upset. Ivanchuk's game with WGM Petra Papp was very level for a very long time, but someone he pulled it out. Yu Yangyi was even lost against IM Sahl Bjarke, but he too managed to win. But while they escaped against their much lower-rated opposition, Gelfand, Nigel Short, Surya Ganguly, and Romain Edouard were all nicked for draws, to talk only about 2600+ players. And two 2600+ players lost: Abhijeet Gupta and Grigoriy Oparin.

    It's an enjoyable 10-round tournament for the spectators, and I'd recommend checking out their website. There's live, on-scene commentary, player interviews, and master classes to boot. Wijk may be the headliner for a few more days, but don't forget about Gibraltar!

    Wijk aan Zee 2017, Round 9: So Still Leads After Almost All the Games End in Draws

    It was a quiet round in terms of results, with six draws in seven games, but there was plenty of turbulence within the games themselves. Magnus Carlsen defeated Loek van Wely pretty easily (clearly better out of the opening, a pawn up 10 moves later, in a clearly winning rook ending about another 10 moves after that followed by a smooth conversion). That brought him back where he was before his loss to Richard Rapport in the previous round; namely, within half a point of the leader, Wesley So.

    So had White in a Vienna Variation of the Queen's Gambit against Levon Aronian, and as the latter was well-prepared it was soon obvious that the game would finish in a draw. So remained in clear first with 6/9, while Aronian was a point behind.

    Two players had an excellent chance to catch up with So. Pavel Eljanov was clearly winning against Dmitry Andreikin in a fantastically complicated game, but couldn't put him away and the game finished in a perpetual. Wei Yi's game with Baskaran Adhiban was quieter (to be fair, most of Tal's games would have been quieter than the Eljanov-Andreikin adventure), but in this game too the player nipping at So's heels should have won, but didn't.

    Of the remaining draws, Ian Nepomniachtchi also failed to convert a winning advantage, though unlike Eljanov and Wei Yi he is nowhere near the top of the tournament table. His fortunate opponent, Penteala Harikrishna, isn't quite in the leading group, but is still close enough to make a run in the last four rounds. As for Anish Giri vs. Richard Rapport and Radoslaw Wojtaszek vs. Sergey Karjakin, those were correct draws.

    My analysis of Carlsen-van Wely is here, and these are the pairings for round 10 (which won't be in Wijk aan Zee, in an implicit rebuke to my labeling this tournament in the traditional way rather than after its current sponsor, Tata Steel):

    • Aronian (5) - Rapport (3.5)
    • van Wely (1.5) - Giri (4.5)
    • Harikrishna (4.5) - Carlsen (5.5)
    • Adhiban (5) - Nepomniachtchi (3.5)
    • Eljanov (5.5) - Wei Yi (5.5)
    • Karjakin (5) - Andreikin (4)
    • So (6) - Wojtaszek (4)

    Things are tightening in the Challengers Group after the co-leaders scored .5/2 between them. Ragger only drew with White against Tari, while Jones was mated by Xiong. Smirin defeated Van Foreest with Black, so now he and Ragger share first with 6.5/9, half a point ahead of Xiong and Jones, a further half a point ahead of Hansen and Lu Shanglei.

    Wijk aan Zee 2017, Round 8: So Still Leads, Rapport Beats Carlsen

    There wasn't much excitement in Wesley So's game. Sergey Karjakin played a slow system with White against the leader, and by move 22 they were already content to shake hands and call it a day. That meant that Wei Yi, Pavel Eljanov, and of course world champion Magnus Carlsen could catch So with a win.

    Wei Yi's game with Pentala Harikrishna was a short draw with Black in a Petroff, so nothing doing there. Eljanov, however, was winning against Radoslaw Wojtaszek, and at two different points in the game. Unfortunately for the early leader of the tournament, he failed to convert his advantage, and also drew. Still, that's better than what happened to Carlsen. Carlsen more or less equalized against Richard Rapport, but chose a very bad play with 22...d3 23.e3 Ne5. Perhaps this was due to a surfeit of ambition; whatever the case, he was losing two moves later, and Rapport finished with a nice little combination starting with 29.Rb6. It had been a bad tournament for Rapport and a good one for Carlsen, but even so Rapport is too strong a player for even Carlsen to take such liberties against.

    In other games: Levon Aronian demonstrated an interesting new idea in the Catalan and won a terrific game against Anish Giri, and Baskaran Adhiban also won in crushing style against Dmitry Andreikin. Finally, in a battle between players at and near the bottom of the crosstable, Loek van Wely failed to convert a winning advantage against Ian Nepomniachtchi, and they eventually drew the longest game of the round.

    The decisive games, with my comments, are here, and here are the pairings for round 9 (on Tuesday):

    • So (5.5) - Aronian (4.5)
    • Wojtaszek (3.5) - Karjakin (4.5)
    • Andreikin (3.5) - Eljanov (5)
    • Wei Yi (5) - Adhiban (4.5)
    • Nepomniachtchi (3) - Harikrishna (4)
    • Carlsen (4.5) - van Wely (1.5)
    • Giri (4) - Rapport (3)

    In the Challengers section, six of the seven games were drawn, which is very unusual - all the prior rounds had at least three decisive games (and that low number only occurred once, in round 1) and one round even saw seven decisive games out of seven. The only non-draw featured players near the bottom of the table, so the relative standings are the same: Jones and Ragger lead, half a point ahead of Smirin and a full point in front of Lu Shanglei and Xiong.

    Wijk aan Zee 2017, Round 7: So Still Leads

    Wesley So continues to lead the Masters group at the Tata Steel chess tournament with 5 points, but that is only good for a half-point edge over the troika of Magnus Carlsen, Pavel Eljanov, and Wei Yi.

    In round 7 So had White against Eljanov, and although he had a slight edge in the opening Eljanov outplayed him in the second half of the game, though not quite enough to muster serious winning chances.

    Carlsen really should have caught him, but he faltered badly against Anish Giri. Carlsen played a great first half of the game, and had mate in three (more or less; Black could avoided the mate by accepting catastrophic material losses). With plenty of time on the clock Carlsen missed this and went for another, significantly less convincing winning line, and botched that one too. Giri hung on like grim death and got the draw after 123 moves.

    As for Wei Yi, he joined the tie for second by beating Loek van Wely. Van Wely was badly prepared and was lost after just 14 moves, and although Wei Yi made life a bit more difficult for himself than he needed to he was still in control all the way.

    The day's other winners were Sergey Karjakin and Baskaran Adhiban. Karjakin beat Levon Aronian in what a very nice, clean positional game, marred only by his missing a chance to win the game on move 11. As for Adhiban's win, it was a messy see-saw struggle with Radoslaw Wojtaszek that won't make either player's best games collection.

    As usual, I've annotated all the decisive games, and as a bonus I've included Carlsen-Giri as well, here. Here are the round 8 pairings:

    • Aronian (3.5) - Giri (4)
    • Rapport (2) - Carlsen (4.5)
    • van Wely (1) - Nepomniachtchi (2.5)
    • Harikrishna (3.5) - Wei Yi (4.5)
    • Adhiban (3.5) - Andreikin (3.5)
    • Eljanov (4.5) - Wojtaszek (3)
    • Karjakin (4) - So (5)

    In the Challengers group almost all the leaders won their games, so the top standings look like this:

    • 1-2. Jones, Ragger 5.5
    • 3. Smirin 5
    • 4-5. Lu Shanglei, Xiong 4.5

    Potentially major games in round 8 include Smirin-Ragger and Lu Shanglei-Xiong.

    This Week's World Chess Column: Taking a Look at the Wijk aan Zee B Group

    The column is here, written before round 6 and thus focused on Markus Ragger's early success.

    Wijk aan Zee 2017, Catching Up!

    I disappeared for a few days, but the momentous occasion that took place on Friday, the 20th of January in 2017 has brought me back to blogging. I refer, of course, to Anish Giri's winning a game of chess at a classical time control.

    So let's get caught up on the action from rounds 2-6. Pavel Eljanov led through round 4, building on his first round win over Richard Rapport with further wins over Loek van Wely (round 2) and Baskaran Adhiban (round 4) - both with Black. Unfortunately for Eljanov things weren't so great with White: he could only draw with Pentala Harikrishna in round 3 and then lost to Levon Aronian in round 5.

    That dropped him into a tie for second with Magnus Carlsen, who won a couple of beautiful games with the white pieces, first against Radoslaw Wojtaszek in round 2 and against Wei Yi in round 4.

    The leader, however, is Wesley So. Like Eljanov, he has won three games - three in a row from rounds 3-5 - but unlike Eljanov hasn't lost any games. He was in grave trouble against Rapport in round 3, and probably should have lost that game, but Rapport faltered near the time control and lost the game. So's win over van Wely in round 4 wasn't overwhelming either, but van Wely made too many errors leading up to the time control to save the game. So's win in round 5 over Harikrishna was clean by comparison, but there too he didn't play anything close to his best chess, and he was also given a big headstart by Harikrishna's poor opening preparation. If So keeps playing so-so chess, he is not going to win the tournament, but if he can work his way into his best form his chances will be excellent.

    Other notables: Aronian, Giri, and Wei Yi are all +1. Aronian's one victory was already mentioned (with Black in round 5 against Eljanov), Giri inflicted a speedy defeat on Ian Nepomniachtchi in round 6, and Wei Yi's round 4 loss to Carlsen was offset by a win in round 2 over Nepomniachtchi and a round 6 victory over Rapport.

    I've analyzed all the decisive games from round 2-6, here. As for round 7's pairings, here they are:

    • Karjakin (3) - Aronian (3.5)
    • So (4.5) - Eljanov (4)
    • Wojtaszek (3) - Adhiban (2.5)
    • Andreikin (3) - Harikrishna (3)
    • Wei Yi (3.5) - van Wely (1)
    • Nepomniachtchi (2) - Rapport (1.5)
    • Carlsen (4) - Giri (3.5)

    In the B-group (aka the Challengers tournament) Top seed Markus Ragger raced out to a 4-0 start before drawing in round 5 in a game he probably should have won. The co-second seeds also went 3.5/4 in rounds 2-5: Ilia Smirin drew in round 1 before his streak to reach 4/5, while Jeffery Xiong was a further half a point behind as he started the event with a loss to Ragger. (That game was analyzed in my round 1 report.) Oddly, all three players lost in round 6, so the leaderboard there looks like this:

    • 1-2. Ragger, Gawain Jones (Jones's rating is just a touch behind Smirin's and Xiong's, and he's the one responsible for defeating Ragger in round 6): 4.5
    • 3-4. Smirin, Lu Shanglei 4
    • 5-7. Eric Hansen, Jeffery Xiong, Nils Grandelius 3.5

    Hans Berliner, 1929-2017

    Former Correspondence World Champion, over-the-board International Master, and computer chess programming legend Hans Berliner died this past Friday, January 13, at the age of 87, two weeks short of his 88th birthday. He was an impressive figure whose work as a chess programmer indirectly affects almost all of us today.

    Do check out the link above for an overview of his many successes in and contributions to the royal game. Berliner wrote a book a couple of decades ago called The System. There are some interesting bits in the book, but overall it's a bit nuts. It is interesting that as a programmer he realized the impossibility of "teaching" the program to play by logic rather than brute force, but then thought that a relatively simple algorithm was the Rosetta Stone to playing the opening better than even world champions.
