A Position to Pawnder - Pyre's Reflections on his Journey into the World of Chess

The following is an article written by Pyre, one of my chess students, reflecting upon his transition from competitive SC2 to chess. My thoughts on Pyre's progress will be published here soon.

========================================================================

When playing Starcraft, I was very often asked by friends and family, “What is Starcraft?” and “How do you play Starcraft?”. My response was always, “Well, it’s sort of like chess, but faster and more difficult”. On the one hand, who can argue that Starcraft isn’t a faster-paced game? Starcraft is in real time and chess is turn-based. Some Starcraft games end in 5 minutes, while some chess games last for 7 hours! However, I could never have been more wrong when assuming that Starcraft was a harder game than chess. Learning how chess pieces move is one thing, but mastering the art, beauty, and complexity that encompasses it is as different as night and day. 

Pyre used to be one North America's most promising SC2 talents and was consistently ranked among TOP 16 on the GM ladder before he turned his attention to chess

Optional Backstory:

      If you don’t know who I am, it's because I haven’t logged onto battle.net for about 8 months. Back in September, I joined my high school’s chess club thinking that my strategic brain would easily be able to convert my grandmaster Starcraft abilities into grandmaster chess play. I was terrible at first, and the mere thought of eventually becoming good at chess was slowly slipping away. I lost to every single person in the chess club every week and wondered why I was good at Starcraft and not good at chess. But eventually, the constant defeats and humiliation got to me and I decided to seriously train to become better. The same competitive drive I applied to Starcraft in my humble beginnings was being applied to chess. What began as a side-project to Starcraft shortly took over as I regained the desire to become better at something--the same something that attracted me so much to Starcraft in the first place.

      With this ambition, I was lucky enough to fall under RevTiberius's wing and become a chess student of his. Soon enough, I started to see results. It was not long before my first competition happened, which was the culmination of all the high schools nearby and I got third place. Good right? Well, not as good as I had hoped. All this did was tell me that I still had a really long road ahead of me. But after several hours a day of studying and playing from January to now, I can confidently say that my chess is at a decent level (approximately 1800 ELO from 1000 ELO) and I hope to continue at the same rate during my stay at UCSD. 


 "I could never have been more wrong when assuming that Starcraft was a harder game than chess". SC2 GM and chess enthusiast Pyre reflecting upon chess and SC2
      “We ain’t so different you and I”. It’s true. Both Starcraft and chess are similar games where both players start evenly and through smart decision making, the better player should win. There are starting imbalances very similar to that of terran, protoss, and zerg, although I doubt “white” is going to get patched anytime soon. There is a large amount of theory, strategy, and overall knowledge required in both games to be successful. Taking expansions in Starcraft is the same as developing your pieces and castling (bringing your king to safety, while bringing your rook into the game) in chess. Going for a baneling bust, or a 6 pool, is very similar to the infamous “Scholar’s mate” (trying to checkmate your opponent in 4 moves) in chess or even just moving your queen out too early and trying to do damage with it. 

      The strategy in both games is really no different. In both games, you build an army and often there is a main fight that decides the game. For all you positional, quiet players who like to “turtle” in Starcraft, guess what? You can do that in chess, too--just close up the position with pawns and its equivalent to a widow mine and siege tank line! And for all you attacking players who like blink stalker openings, roach baneling busts, and 1/1/1s, there’s aggressive type play in chess as well with what are known as gambits (sacrificing material for hyperaggression). 

      Both games have gone through changing times and changing ideas throughout their existence. In the beginning of Starcraft 2 in 2010, everyone (including zergs) opened on 1 base and it remained that way until even the 7 minute mark. Struggling, zergs eventually realized that they needed the extra larvae and they needed the extra base, so they started going hatch first. As a response, terrans started making reactor hellions to start putting pressure on the expansion. These are examples of trends. From the 1500s-1800s, chess players strived to control the center immediately and valued fast development. However, at the dawn of the 20th century, ideas changed and certain people (called “hypermodernists”) decided that as a response, chess players could let their opponent control the center at first, but then flank attack it later! This idea had never been seen before, but it changed the way people thought chess was played and it led to even more innovation further down the road. 

      Tournaments are seen in both chess and Starcraft 2 at the professional level and the amateur level. One of the most intriguing things I had found out about when I first started getting into chess was the fact that most local chess tournaments have sections. This was a new thing to me, as no Starcraft tournament I ever went to had a “diamond-only” section or a “platinum-only” section with cash prizes for them too. This seemed genius to me. Everyone who participated in these chess tournaments had something to play for. They weren’t just going to get “beat by a gm, then watch”.

      There are also chess pros, just like there are Starcraft pros. The “Flash” of chess would be either Garry Kasparov or Bobby Fischer. Both of these chess players are legends of their time and have been internationally recognized outside of the chess world. The “Taeja” or “Mvp” of chess would be Magnus Carlsen. Magnus Carlsen is currently the world #1 at only 22 years old! He is a superstar in his own world just as Starcraft players are in theirs.

      If you’re a fan of just one of these games, then I highly encourage you to try the other. As a non-Starcraft player, if you feel intimidated by the speed at which Starcraft is played, let me assure you that you don’t need 450 APM to be good. Plenty of successful Starcraft players, like Polt, are able to out-think and outplay their opponents purely out of strategy, tactics, and immense game knowledge. If you play Starcraft and have never gotten into chess, then just imagine you’re playing Starcraft except without the APM and constant movements--just the strategic portion. Nothing can match the pleasure of beating someone in a game of raw intellectual strength.

Episode VI - How to Analyze a Position and Formulate a Plan

A critical skill for any chess player to have is the ability to accurately and systematically analyze positions. During a chess game it is very tempting to just look at "interesting" moves or randomly start calculating variations. This approach however, will almost always neglect the deeper positional characteristics of a position. And unless you're playing blitz, this will also make it hard to make good use of the time allotted to you.

Therefore, now that we have covered some of the basic tactical elements in chess, in our last lesson I taught Pyre a more systematic way to analyze a position, and form a plan based on the results of the analysis.

There are many good books about this topic. I think eventually I'll post a list of useful resources for beginners and novices. The approach I was taught many years ago by my first chess coach is based on Karpov and Mazukevich's recommendations in their book "Find the Right Plan". By the way I think this is a book that does not get the attention it deserves.

The basic idea is that in order to choose the right course of action, a chess player must first have a good understanding of the current position. This will not only make it easier to select a good plan, it will also help identifying candidate moves.

According to Karpov and Mazukevich, to get a good understanding of any given position, a player must look at each of the following 7 evaluation criteria:

1. Material Balance
2. Immediate Threats
3. King Safety
4. Open Files
5. Pawn Structure, Strong and Weak Squares
6. Center and Space
7. Development and Coordination among minor and major pieces

This analysis does not need to be performed after every move, but it has to be done regularly. For example, a player could form the habit of doing this after move 10, 20, 30, 40 etc. This analysis should also be done whenever the position on the board changes dramatically, for example after a player sacrifices material.

After discussing these principles in general terms, Pyre and I looked at an example to practice this approach. We analyzed the game between Boris Gelfand and Vassily Ivanchuk from the 2013 Canadidates Tournament in London, which had been played earlier the same day. The players reached the following position after Gelfand's 17th move Ng5:

Gelfand-Ivanchuk at the 2013 FIDE Candidates Tournament in London 2013; position after 17. Ng5
We tried to to come up with a good plan for Black. As the first step, we analyzed the position through the lens of the 7 evaluation criteria:

1. Material Balance: the material balance is even. The only difference is that White has the bishop pair and a knight while Black has two knights an a bishop.
2. Immediate Threats: neither side has any immediate tactical or positional threats.
3. King Safety: Both kings are fairly safe. Black and White have castled queenside which means that neither side can easily launch a pawn storm on the opponent. Due to the missing c-pawn, White's king is a little bit more exposed, but this will probably not have a significant impact on the game.
4. Open Files: There are no open files in this position. White has the half-open c- and g-files available to him and could potentially double up rooks on either of them. Black currently controls the half-open d-file.
5. Pawn Structure, Strong and Weak Squares: Despite the double pawn on the f-file, White has the better pawn structure. He doesn't have any potentially weak pawns. At the same time his pawns control many important central squares.
White has strong squares on e5 and g5, and possibly c5 even though Black can control that square with a pawn if necessary. F3 is a weak square though it is currently not easy for Black to place a piece there. White's pawn structure also does not have any real weaknesses.
Black on the other hand has (somewhat) strong squares on e4 and d5, but also several weak squares: e5, g5 and g6 are permanently weak, and c5 can only be controlled if Black is willing to compromise his queenside pawn structure. The backward pawn on g7 is weak and in an endgame the pawns on e6 and h4 are potential weaknesses as well.
6. Center and Space: The center is closed. White has a slightly more solid pawn mass in the center while Black's minor pieces better control the central squares. Neither side has an obvious space advantage. Both Black and White have more mobility on the queen side than the king side.
7. Development and Coordination among minor and major pieces: Both sides have completed their development. The white knight on the strong square g5 looks impressive, but it is unclear what role it serves there. This in fact may be a good example that a "strong" square isn't necessarily also a "useful" square. White also has the bishop pair.  The bishop on c4 is very strong indeed, indirectly targeting the Black's weak pawn on e6. The bishop could also pin Black's knight on c6, which could be very unpleasant for Black indeed, especially if White doubles up in the half-open c-file. However, White's main problem and in fact the defining characteristic of this position is the bad bishop on h2. The bishop doesn't contribute anything to White's game, and activating or exchanging it will require a lot of time.

Formulating a Plan:
After this in-depth analysis of the position, we started formulating a plan for Black. In my opinion assessing the 7 evaluation criteria is the easier part. It is more difficult to come to the right conclusion what the analysis of these criteria means, and which of the criteria are more important than others in any given position. For example, is it more important that White has the better pawn structure in this position, or that Black has two knights, which in a closed position such as this one should be favorable? It takes a lot of skill and experience to draw the right conclusions from the analysis. However, for Pyre's purposes it isn't important to get it right 100% all the time. In fact, even grandmasters regularly get this kind of analysis wrong. The point is that if Pyre learns to do this analysis regularly and systematically, he'll be able to take his chess to the next level.
In this example the critical point is to realize that White's bad bishop on h2 is the single most important characteristic of the position.
Basic chess strategy recommends that when one of your opponent's pieces is - temporarily or permanently - locked out of the game, the right course of action is typically opening up the game on the other side of the board because that is where in essence your opponent will be a piece down.
In this position Black can achieve that by playing c7-c5, ideally after bringing the rooks over to the c-file. The thrust c7-c5 opens the position without exposing Black's king too much.

And this is pretty much what Ivanchuk did in the game. The entire game can be found here:
http://www.chessgames.com/perl/chessgame?gid=1713206

The game ended in a draw because as so often Ivanchuk ended up in time trouble and couldn't convert the very promising position he achieved after opening the game on the queenside.
However, for the purpose of this exercise it isn't necessary to analyze the remainder of the game. The important point was to do an in-depth analysis of a given position with Pyre, which is something we'll keep doing going forward.

Vassily Ivanchuk and MarineKingPrime
A Word about Vassily Ivanchuk:

To me, Vassily Ivanchuk is the MarineKingPrime of the chess world. "Chucky" as he's called is one of the most brilliant players on the chess circuit, and has been a dominant force at the top level for many years. However, his inability to keep his nerves under control has prevented him from ever being a serious contender for the world championship title, or win more top level tournaments. In the 2013 Candidates tournament alone he's already lost 3 games on time.

Despite his volatile performance, Ivanchuk is one of the very few players who, on a good day, can beat anybody, including Carlsen, Anand, and the rock-solid Kramnik.

All of this is very reminiscent of MarineKingPrime who clearly has the skills to win MLGs but rarely does so because - among other things - it seems he is a little too emotional and nervous.

The following clip is from a chess olympiad match between Ivanchuk and Kramnik:



I'd be nervous too if I was playing Vladimir Kramnik, though 2700 ELO Super GMs typically play their moves a little more confidently than Ivanchuk does here.

Nevertheless, Ivanchuk is a fan favorite, and I have great admiration and respect for his creative chess, too!
