# Chess/Sample chess game

This is a sample game of chess, recorded in standard algebraic chess notation and accompanied by commentary.
White has the first move and therefore a significant initiative. White wins 10% more often than Black simply on the power of that initiative. It is important not to squander the opening advantage with a move that does nothing.

##### 1. e4

White chooses an excellent move, common among beginners and experts alike. The move has several advantages:
* It stakes out territory in the center. A player who controls the center with pawns will probably be able to find good squares for their pieces.
* It opens a diagonal for the king's bishop to move out and attack, which also facilitates kingside castling.
* It opens a diagonal for the queen to move out and attack.
This move follows the two most important principles of an opening move: 1. develop a piece, or facilitate the development of a piece, and 2. control the center.

| | a | b | c | d | e | f | g | h | |

##### 1... e5

This move for Black is good for the same reasons listed above. Note that the two e-file pawns are not threatening to capture each other, because pawns capture diagonally. Instead, they merely block each other until something breaks the logjam.

| | a | b | c | d | e | f | g | h | |

##### 2. Nf3

White makes another fine move. White is mobilizing forces by bringing a knight forward into an attacking position. Because the white knight is attacking Black's e-pawn, White is maintaining the initiative by forcing Black to react. So now, Black must choose a move that defends the pawn, or else he might lose it. The initiative may appear to offer only a slight edge, but at the hands of a master, it can be deadly.
White could have moved out the queen instead, but that would be dangerous. The queen is generally too valuable to trade for any other piece except the enemy queen (however, it can be traded for multiple enemy pieces of equivalent total value, such as two bishops and three pawns; two bishops and a knight; or a rook, a bishop, and a pawn, for instance), so it can't do much by itself unless the opponent carelessly leaves pieces unprotected. Thus, your opponent can keep attacking your queen with different pieces. And while you are simply moving your queen around, your opponent will be able to keep developing their pieces. It is better to wait until there are other pieces in the fray which can serve as shock troops for her.
White also could have moved out the kingside bishop. That would not be a bad idea, but it isn't clear yet whether the bishop wants to be at c4, b5, or possibly even behind the pawns. The knight, on the other hand, usually goes to f3 anyway, because the other squares it could move to are inferior: on h3, it would not attack the center, and on e2, it would be temporarily in the way.

| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 2... f6?

Black makes a worthless move, entering the infamous Damiano Defense. Black needed to defend his pawn with either 2...Nc6 (main line) or 2...d6 (Philidor Defense), or counterattack White's pawn with 2...Nf6 (Petrov's Defense). Either of the knight moves would have maintained the balance of the game by contesting the center. If Black felt brave, he could also venture into the murky waters of 2...f5 (Latvian Gambit) or 2...d5 (Elephant Gambit).
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. This weakening is called "opening the door," and White must take advantage of this.
Black has failed to follow the principles here and has received no compensation. He has affected the center, but the move 2...d6 would have done the same and gained some control on the queenside. Also, he has not developed a piece, nor has he facilitated the development of a piece. 2...Nc6 would have developed and gained control in the center, and 2...d6 would have gained some control on the c8–h3 diagonal and facilitated the development of the light-squared bishop. Black has also weakened his kingside. Any pawn moves in front of a castled king can be useful weaknesses for the opponent. Since pawns cannot go backwards, you should be very cautious of any pawn moves on the side you wish to castle on (usually the kingside).
The moves 2...f5 and 2...d5 seem to not adhere to the principles. Why have these moves been brought up? The fact is that the best moves in a position will sometimes break principles, but they will offer compensation for whatever gains are lost by not following the principle. So, in a sense, the principles tell us what questions to ask ourselves when making a move, such as, "Should I develop now?" So it is important to understand the principles in order to decide if you are getting enough compensation. It is not always good to blindly do whatever the principles dictate.

| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 3. Nxe5

White attacks immediately, sacrificing the white knight for a pawn, although White would generally need three pawns for the knight to have material equality. Before making this sacrifice, White has to calculate to make sure he is going to gain something that compensates for the lost material. In this case, as the following moves show, White knows that he will gain an attack on the enemy king, forcing Black to either surrender more material or allow checkmate.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |
| 7 | | | | | | | | | 7 |

| | a | b | c | d | e | f | g | h | |

##### 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 and pawn and putting pressure on White's 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 kingside 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.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |

| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 4. Qh5+

The game's first check! There are three legal ways to respond to check:
* Capture the piece giving check. Here, this is impossible, as Black has nothing which can move to h5.
* 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.
* 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 to move 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.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |
| 7 | | | | | | | | | 7 |
| 6 | | | | | | | | | 6 |

| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 4... Ke7

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.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |

| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 5. Qxe5+

Another check. Black now has only one legal move: Black can't interpose anything between the king and queen, and he 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 threatening.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |
| 7 | | | | | | | | | 7 |

| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 5... Kf7

Black moves the king; it's the only available move to play. 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 that the white queen could target is defended by something, so the queen has done all it can do by itself. It is time to bring in reinforcements.

## Moves 6-10

| | a | b | c | d | e | f | g | h | |

##### 6. Bc4+

This is an excellent move to keep the pressure on Black because it develops a piece and gives check while preventing Black from consolidating.
If White had played less energetically with 6.Nc3, the advantage would have evaporated instantly. Black could answer with 6...Nf6, bringing a piece to the defense. If Black gets his king to safety, Black might actually be winning: White has only two pawns for the sacrificed knight, giving him a material disadvantage.

| | a | b | c | d | e | f | g | h | |

##### 6.... d5!

Black makes an excellent defensive move. Never forget that 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 counterattack.
| | a | b | c | d | e | f | g | h | |

| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 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:
* Capture the piece giving check. Black could play 7...Qxd5. However, White would simply take the queen with 8.Qxd5+. With such a huge material disadvantage and an exposed king, Black could resign without feeling like a quitter.
* Interpose a piece. Black could play 7...Be6. However, 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#.
* 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.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |
| 7 | | | | | | | | | 7 |
| 6 | | | | | | | | | 6 |
| 5 | | | | | | | | | 5 |
| 4 | | | | | | | | | 4 |
| 3 | | | | | | | | | 3 |
| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 7... Kg6

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.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |
| 7 | | | | | | | | | 7 |
| 6 | | | | | | | | | 6 |

| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 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 is important in some mating combinations. Finally, there is some chance the rook will be able to join the attack down the h-file.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |
| 7 | | | | | | | | | 7 |
| 6 | | | | | | | | | 6 |
| 5 | | | | | | | | | 5 |
| 4 | | | | | | | | | 4 |

| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 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 enough 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."
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |
| 7 | | | | | | | | | 7 |
| 6 | | | | | | | | | 6 |

| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 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 of four extra pawns, and he can win slowly and surely with patient developing moves like 12.Nc3. (Note that after 9...Bd6 10.Qa5, Black cannot play 10...Bxb7 because of 11.Qf5+, with the same play as in the main variation below.)
As it happens, Black does not understand the danger.
| | a | b | c | d | e | f | g | h | |
| 8 | | | | | | | | | 8 |
| 7 | | | | | | | | | 7 |

| 2 | | | | | | | | | 2 |
| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 9... Bxb7?

Black grabs the bishop to gain a material advantage (bishop plus knight versus four pawns). This is Black's critical error, allowing White's attack to break through. From here on, White has a forced mate.
| | a | b | c | d | e | f | g | h | |

##### 10. Qf5+

The crushing move can be unleashed at last. Black has only one legal reply.
| | a | b | c | d | e | f | g | h | |

| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 10... Kh6

This is the only move to get out of check: the white queen cannot be taken, and any other moves for the king would leave it under attack.

| | a | b | c | d | e | f | g | h | |

##### 11. d4+

White continues the attack with a special kind of check, a 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. But because it is an option, this is not yet checkmate.

| | a | b | c | d | e | f | g | h | |

##### 11... g5

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 is 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.

##### 12... Qe7

Nothing can save Black now 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 that 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+! However, White must have foreseen this possibility when playing his last move.

| 1 | | | | | | | | | 1 |
| | a | b | c | d | e | f | g | h | |

##### 13. hxg5+

This checks Black's king and destroys Black's pawn cover. Black can't get out of this check by interposition or by moving the king away. All retreat is cut off by White's well-placed queen. The only option is to capture the checking piece.

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 Black's queen 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 has been behind in material almost the entire game, including in the final position, but comes away with the victory nonetheless.
