Po 1. e4.

1. e4

Beli ima prvo potezo in s tem pomembno prednost, zaradi katere beli v povprečju zmaga 10% bolj pogosto kot črni.

Beli je izvral dobro potezo, pogosto med začetniki in tudi med poznavalci. Poteza ima več prednosti:

  1. Zavzame prostor v središču. Igralec, ki nadzoruje središče s svojimi kmeti ima pomembne prednost.
  2. Odpira diagonali za damo in lovca.

Poteza je dobra za črnega iz podobnih razlogov, kot so navedeni za belega. Kmeta se ne napadata, saj jemljeta diagonalno pač pa se blokirata.

2. Nf3

2. Nf3 (Skakčeva otvoritev, C40)

Beli vključuje v igro nove sile, hkrati napada kmeta na e5. Poteza je precej boljša od Sh3, kjer je figura na robu ali Se2, kjer blokira lastne figure.

Beli sicer bi lahko odigral z damo, vendar se v otvoritvi praviloma igra najprej z lahkimi figurami. Beli bi lahko igral tudi z lovcem na c4 ali b5, ki sta tudi znani otvoritvi.

Skakčeva otvoritev in ouznaka C40 opisujeta vrsto otvoritve. Imena otvoritev so se razvijala skozi stoletja, za bolj natančen opis glejte ECO.

2... f6

2... f6?

Črni je odigral slabo potezo, kar označimo v zapisu z vprašajem. Poteza vodi v slabo varianto Damianova obramba.


Black needed to defend his pawn with either 2...Nc6 (main line) or 2...d6 (Philidor Defense), or counter-attack White's pawn with 2...Nf6 (Petrov's Defence). If Black felt brave, he could also venture into the murky waters of 2...f5 (Latvian Gambit) or 2...d5 (Elephant Gambit). Either knight move would maintain the balance of the game by contesting the center.

The move 2...f6 appears to defend the threatened e-pawn, but this is an illusion, as the game shall demonstrate. Black has weakened the kingside, allowing attacks on the f7 square, which is protected by nothing other than the king itself.

3. Nxe5!

3. Nxe5!

White attacks immediately, sacrificing the white knight for two pawns, although generally White would need three pawns for the knight to have material equality. Although White can't calculate far enough ahead to know exactly how the sacrifice will pay off, it is judged that the attack will be at least strong enough to compensate. If White weren't confident of the soundness of this sacrifice, either 3.d4 (occupying the center) or 3.Bc4 (pointing the bishop at Black's weakened king-side) would also be strong.

3... fxe5

3... fxe5

Black makes the only move consistent with 2...f6, but it is not best. The best try for an equal game was 3...Qe7, skewering White's knight, pawn, and king. That is to say, the queen would indirectly be attacking everything in the e-file. After the knight moved away, the queen could take on e4 with check, regaining the pawn. White would, however, have a large advantage because of his lead in development and Black's weakened king-side pawn structure, e.g. 4.Nf3 Qxe4+ 5.Be2, likely followed by 0-0 and Nc3 (attacking the queen).

Retaking the knight now merely invites White's queen to jump into the fray with check. The fact that Black cannot afford to take the knight shows that 2...f6 did not really protect the pawn at all.

4. Qh5+

4. Qh5+

The game's first check! There are three legal ways to respond to check:

  1. Capture the piece giving check. Here this is impossible, as Black has nothing which can move to h5.
  2. Interpose a piece between the king and the piece giving check. Black could play 4...g6. But that would lose a rook to 5.Qxe5+ and 6.Qxh8.
  3. Move the king out of check. Moving the king to f7 leaves it in check, and is thus illegal, so e7 is the only square for moving out of check.

Note that White has forked the king on e8 and the pawn on e5. There is no time for Black to protect both, so no matter what Black does to get out of check, White's queen can take on e5.

Normally, it would be a bad idea to move out a queen this early in the game. But Black's exposed position makes it worthwhile.

This move leaves Black in a dangerous position, because the black king is so exposed. Furthermore, the black rooks, bishops, and queen still have no way to get out. The Black position is no more developed than it was at the start of the game.

5. Qxe5+

Another check. Black now has only one legal move. Black can't interpose anything between the king and queen, and can't take the queen, so the black king must be moved out of check. There is only one square next to Black's king which White's queen is not attacking: f7 (marked with an X on the diagram).

5... Kf7

White's queen is a dangerous attacker. However, because it is too valuable to trade for anything, it can only take undefended pieces. Everything in Black's camp is defended by something, so the queen has done all it can do by itself. It is time to bring in reinforcements.

6. Bc4+

6. Bc4+

This is an excellent move to keep the pressure on Black. Because it develops a piece and gives check, White prevents Black from consolidating.

If White played less energetically with 6.Nc3, the advantage would evaporate instantly. Black could answer with 6...Be7, giving the king room to retreat to f8. Once Black gets his king to safety, Black might actually be winning. White has only two pawns for the sacrificed knight, which leaves White at a material disadvantage.

6.... d5

6.... d5

Black makes an excellent defensive move. Moving the king isn't the only way to get out of check!

Admittedly, Black's d-pawn is a dead duck. It is attacked by White's bishop, queen, and pawn, three times altogether, while it is defended only once, by Black's queen. The sacrifice is worthwhile, though, to open up lines for the queen and bishop so they can help with the defense. Now if White fails to find the best continuation, Black has some chance to counter-attack.

This move is necessary, since 6...Kg6? 7.Qf5+ Kh6 8.d4+ g5 9.h4! would leave White with a crushing attack.

7. Bxd5+

7. Bxd5+

White gives check yet again, which prevents Black from doing anything constructive. Let's review the three ways to get out of check:

  1. Capture the piece giving check. Black could play 7...Qxd5. But White would simply take queen with 8.Qxd5+. With such a huge material disadvantage and an exposed king, Black could resign without feeling like a quitter.
  2. Interpose a piece. Black could play 7...Be6. But that would be inadvisable, because the bishop would be defended only once (by Black's king) and attacked twice (by White's queen and bishop). In fact, White could end the game at once with 8.Qxe6++ checkmate.
  3. Move the king. Alas, the only square which is not under attack by White is g6, even further into the open. It beats the alternatives, though.

Now White must think of a way to continue the attack. White would like to play 8.Qf5+, driving Black's king to h6 where it can be cornered and checkmated, but Black's c8 bishop is guarding the square f5. If Black hadn't interposed with 6...d5, Black would now be subject to a forced checkmate. As it stands White has to be more creative to keep the initiative.

8. h4

Again White finds a strong continuation. White is threatening to force the Black king to h6 after all with h5+. Also the pawn protects the g5 square, which may turn out to be important down the road. Finally, there is now some chance the rook will be able to join the attack down the h-file.

8... h5

8... h5

Black plays a tenacious defense in a precarious situation. White's pawn is blocked from further advances, and the king has a new escape square on h7. Black's position is still precarious, but there is no immediate way for White to force checkmate.

Now let us take a step deeper into chess reasoning. White knows Black is on the run for the moment, but if Black has a chance to regroup, the game is far from over. Three pawns for the sacrificed knight is roughly material equality.

If White brings additional forces forward with 9.Nc3 or 9.d4, the obvious developing moves, Black will harass White's queen with 9...Bd6. That would force White to lose time protecting the queen. Black would gain time to get the black pieces out and get the black king to safety.

White desperately wants a quick kill, but can't see how to get it. White is annoyed that Black's bishop on c8 prevents White from playing 9.Qf5+ and administering the coup de grace. Therefore White asks the question, "What if Black's bishop were not on c8? If only that annoyance were removed, I could do great things."

9. Bxb7

White finds a forceful continuation that puts Black in dire straits. Black's best bet now is to ignore White's bishop and harass White's queen with 9...Bd6, but then White calmly plays 10.Qa5, maintaining the threat on f5 and forcing Black to lose material. One possible line of play is 9...Bd6, 10.Qa5 Nc6, 11.Bxc6 Rb8. The checkmate has been avoided, but now White has a large material advantage (four extra pawns) and can win slowly and surely with patient developing moves like 12.Nc3, or even snatch a fifth pawn with 12.Qxa7.

10... Kh6

Black had no choice, but note how precarious this position is. Black's king is in extreme danger; it's still very exposed on Black's third row, a bad place to be while there are still powerful pieces such as queens and rooks in play. Black's king has nowhere safe to move, White's queen is extremely near Black's king, and Black's king has an open diagonal right to White's side of the board. Black's rook on h8 is hemmed in and cannot aid the king, and the king also blocks one of the places Black's knight on g8 could go. At the end of move 10, the only pieces Black has really developed (by moving it out) is his king -- and that is definitely not good; the king needs to be protected. White is relatively poorly developed for being at move 10, but White at least has his queen out, and is being well-compensated by having a superior position compared to Black.

White continues the attack with a special kind of check, the discovered check. White moves a pawn, but it isn't the pawn which gives check. It is White's bishop, attacking from its home square, which delivers the blow.

Note that Black's king has no legal moves, and White's bishop is safe from capture, so interposition is the only option.

At this point White has an easy win with 12.Bxg5+ Kg7 13.Bxd8. The material advantage of a queen and five pawns for a bishop and a knight would be overwhelming. However, weak players have been known to play on in completely hopeless positions rather than resign. In order to forestall a long, boring mop-up operation, White looks for a direct kill.

Nothing can save Black short of White forgetting the plan, but there is some logic to Black's move. Where can White's queen go? Any of Black's pieces it could take are protected. If White trades queens, then the attack is over, and Black is winning. Finally, if White's queen simply retreats, Black will strike back with check: 13...Qxe4+!

But White must have foreseen this possibility, or White would never have played 12.Qf7 instead of 12.Bxg5+.

13... Qxg5

13... Qxg5

This move by Black saves the king, but leaves Black's queen open to being captured by a lowly bishop. Black is now vulnerable to White's playing Bxg5, and losing his queen, but a worse fate is possible...

Checkmate. Black can't interpose anything, because the rook is giving check from an adjacent square. Black's king can't move away, because White's queen covers all retreat squares. Black's king can't capture the rook, because then it would be in check from White's queen. Finally, Black's queen can't capture White's rook because it is pinned. If it moved away, White's bishop on c1 would be giving check to Black's king.

Notice that, although material considerations are very important in chess thinking, one doesn't win by having the most pieces. One wins by delivering checkmate. White was behind in material almost the entire game, including in the final position, but came away with the victory nonetheless.
