After this it would seem Black's pieces can handle any threats White can generate. However, black might also have ideas of winning. How might he do that? Well, ...Be8, ...Kc8-b8-a8, ...Rd8-c8, ...Nc5-a4 and Pc3 is a target (slow I know) . Another idea is to keep Kd2 from ever escaping to safety by advancing ...h5-h4-h3 to break open the king-side and open the h-file for Black's rooks.

Black is probably wondering why he organized his pieces to only defend light squares. Only Qa5 and Nc5 can get to dark squares and that makes White's task of coordinating much easier.

Sveshnikov - The idea is to control the center with his extra pawn (Pd7 & Pe7 vs. White's Pe4) and to do so in a way that lets him activate his two bishops more fully than in a Scheveningen; it's somewhat like a Boleslavsky set-up. But, White's pieces aren't placed the same as in a Boleslavsky; instead White goes directly for the weak spots and induces as much weakness in Black's position as possible (capitalizing if possible) .

When this opening was originally played it was thought ...Bc8-e6 was best, but ...b5 (the Chelyabinsk Variation) has become most common. There's the immediate threat of ...b4 and it offers ...Bc8-b7 as an option. It also prevents Bf1-c4.

At last, Black can preparing some offense with ...f7-f5, though it's hard to see how he can achieve much when Rb8 & Nc6 are tied to the defense. On the other hand, Nc2 isn't particularly active at the moment, so White hasn't many defensive pieces on the king-side.

This seems to me to be a key moment for White: it's from here she has to decide on a middle-game plan which will range across the entire board. Black isn't making any specific threats just yet, but the two bishops (Bf5, Bg5) and Rf8 look ominous. I'd suggest not letting Bg5 move to clear for ...Qd8-g5 or ...Qd8-h4, but there is also ...Qd8-e8-g6, so White has to act fast before a calamity happens.

If he's going to fight on light squares then it certainly makes sense to consider ...Ne7, but it weakens Pa5. A key question still remains and that's how Black might try to use Bg5 and how White can reposition Nc2. It might become obvious that Nc2-e3 is necessary, even if it allows Black to trade-off Bg5.

"hitting" e3 to make Nc2-e3 less appealing to White. It also stays in touch with Pa5 and Pb3 and cooperates with Bg5 at a distance. This isn't a plan to win the game, just to maintain cohesion of his position and to keep a little pressure on White. Now is the time for White to return to the main idea of removing Pa5 to make Pb3 a passer.

At the end Polgar could force an entry to Black's king with 37. Ra7+ Kh6 38. Bxe4 Rxe4 39. Qf7. Curiously, Polgar also drew a pawn-down ending against Kramnik (in this event) , beginning with this same opening. One has to wonder what brought the position to this; where White was doing well, but then has to give a pawn and hope to draw. Isn't this a mysterious kind of thing? I suppose White was not fully developed and active (Nc2) and holding back to avoid trades gave Black compensation for the other weaknesses in Black's position. In the end it was those same weaknesses which gave White compensation for the lost pawn. It's back to the drawing board to find a better plan for White.

Among the younger top-flite players (perhaps more from Europe) the more hyper-modern defenses like the King's Indian Defense, Benoni and Benko Gambit aren't seen as often (caveat: Polgar played the KID early-on in her career) .

White defends Pc4 and tries to force Black to relinquish the pressure, while incidentally pinning Pd7. 5. b3 is the most common alternative. Defending Pc4 with the queen almost always results in Black challenging Pd4 to show that the absence of Qd1 is significant.

All secure! A draw is the likely result. White's advantage now is that Ke4 is more advanced and his rooks are a bit more mobile than Black's. In an ending of this sort, a rook's lateral mobility can be very useful.

clearly taking aim at Pg4, though it's unlikely Pe6 would remain on the board if Pg4 is captured. Still, Pg6 is further away from the queen-side and that might make it a better weapon for Black. Also, if ...Kf6-g5xg4 then Black's king would've outflanked Ke4 and would have some advantage in the effort to support the advance of Pg6.

I thought Polgar may have missed an opportunity here, but Fritz7 found a slightly better line for White and keeps the advantage. Essentially, both promote their passers and White's king is better placed (near Pa6) for the resulting Q+P ending. The question for Black is where her king belongs, far away or as close to a8 as possible.

This line is possibly better for Black than the longish note after Black's 53rd move because Black's king is very close to a8. Is this a theoretical win for White? I don't know, but rook pawns are the hardest to advance. Ideally the defending king should stand directly in front of the pawn or very far away to avoid cross-checks (where a queen trade is forced) . Perhaps in this case the awkward White king position makes it alright for Black's king to be close to a8. In the case of many queen trades Black's king just walks to a8 and says 'Draw!'.

White recognizes the need for further piece development and begins a slow build-up. There is also the possibility of Ng1-e2 and a2-a3 to force Bb4 away, thus keeping Black cramped.

Another plan, the Hubner Variation, is to capture at c3, giving White doubled pawns, and then to play the Black central pawns onto dark squares, thereby replacing (to some extent) the missing dark-square bishop. Some players are reluctant to relinquish the bishop.

This Rubinstein Variation aims to force Bb4 to trade for Nc3 or to retreat. Trading gives White a small gain with no cost and the retreat leaves Black without sufficient central control. At least that's the Classical take on this position. I think the first part is right, but the second has to be taken with a grain of salt because Ne2 isn't very good and Bc1 is blocked-in behind Pe3. If Black plays ...d7-d5 or possibly even ...c7-c5 then he's probably alright. It doesn't take a lot of pawn moves to control the center.

neither player's dark-square bishop is very good, but Black's serves a defensive purpose, so White chooses to trade them. The curious part is that ...Bd6xb4 forces a3xb4 when it's not clear how good White's doubled b-file pawns might be.

White has the a-file and still controls c5, but Black has gotten Bb5 to defend Pc6 and guard against Ra6. White probably has to trade-off Bb5 with Bg2-f1, thereby weakening a6, Pb6 and Pc6.

Again Black has everything defended, so White has to force another trade, to remove perhaps Rb8.

Should White trade-off Ph4 or advance it? Sometimes it's good to pose your opponent with even the smallest of questions (like this) as the game nears the time control. It seems hxg5 can be answered by ...Qxg5 and then ...h6-h5-h4 might well continue to threaten White's king. On the other hand h4-h5 isolates the pawn and might lose it. Technically it's possible both are good because weakening Kg8 can't be good without greater piece activity in that region to defend.

What I found interesting about the Fritz7 notes is that it continued to "believe" the position was equal or only slightly better for White, but when the White plan came to fruition it suddenly "saw" it was clearly or decisively to White's advantage. It's horizon effect was rather distinctly noticable.

This is a key move . Black's rooks become too passive
and a powerfully placed knight on f5 or d5 still cannot stop white's break
through on the King-side .

This is one of the variations Polgar plays, so it appears Timman has decided she might not like to face it from the other side. Unlike variations with ...d7-d6 where Black uses an early ...Ng8-f6 to (more-or-less) force White into Nb1-c3 before c2-c4, in this variation the threat of an early ...Bf8-b4 helps to serve the same purpose. The thorny light square pawn structure also inhibits Bf1-c4. So, White usually aims for a Classical set-up with Nb1-c3, Bf1-e2, O-O and possibly Bc1-e3. This is one good way to get a "normal" Scheveningen position without facing the Sozin (Bf1-c4) , Velimirovic (Bf1-c4, Bc1-e3, Qd1-e2, O-O-O) or Keres Attack (an early g2-g4) . The primary cost to avoiding early king-side development (or any preparation to remove Ke8 from the center) is that White has some attacking options.

This is a variation which was conceived in the 1960s, was revived in the 1980s by Karpov (and others) and has become popular again in the 2000s. White can defend Pe4 or attempt to play on the dark squares where Black is a little weak (only pieces guarding b6 & d6) .

Black takes the moment to gain some space in the center. Though it could be argued this just makes it easier for White to force lines open for the two bishops and White's other heavy pieces I think most players would follow Timman's lead.

A Classical evaluation has to note that White has the two-to-one queen-side pawn majority when Black doesn't have a compensating central pawn presence and White has the two bishops. These are slight, but enduring positional advantages. I look at these two elements in terms of whether they help White to win: the bishops are considered a slight material advantage and the pawn majority is considered useful because their distance from the kings means that they can more easily be advanced (particularly in an ending) to create a passer which could promote.
