Bc4 Bg4 5. h3 Bh5 6. b3 {6. b3 With the intention of 7. Bb2} 6... Be7 7. Bb2 O-O 8. Qe2 {8. Qe2 With the intention of a Queen-side castle, to push the King side pawns to cramp the Black's king.} 8... Nc6 9. Qe3 {9. Qe3 Releasing the pin on the Knight to allow it to protect the d4 square, in anticipation of later playing d4.} 9... Na5 10. g4 {10. g4 With the expectation of 10... Bg6. I had expected to move my Bishop on c4 away afterwards, but obviously Black can still capture it with 10... Nxc4.} 10... Nxc4 {10... Nxc4 Creates an isolated and double pawn. This is not good because I had expected to castle Queen-side.} 11. bxc4 Bg6 12. d3 {12. d3 To protect the c and e pawns, and allow my pieces freedom of movement.} 12... c6 13. O-O-O {13. O-O-O Even though my Queen-side pawn structure is broken, I still have the Bishop and Knight to help defend against any Queen-side attacks. I still have full intention of pushing the g- and h-pawns to cause trouble for Black's Bishop and King.} 13... Nd7 14. Rdg1 Qa5 {14... Qa5 There is no threat, so this move is ignored.} 15. h4 h5 16. g5 {16. g5 This move will prevent any possibility of Black's dark square Bishop moving to f6, to aid in a later distance attack on my fractured Queen-side pawn structure.} 16... Nc5 17. Nd2 {17. Nd2 Although 16... Nc5 poses no threat, I do not like all the pressure on my King. I am going to move my Knight later to b3 to force Black to either trade or retreat.} 17... Rab8 18. Nb3 Qb4 19. Nxc5 dxc5 20. Qd2 {20. Qd2 Again, I am going to force black to either trade Queens or retreat, as I do not like all this pressure on my King.} 20... Rfd8 21. Ne2 Qxd2+ 22. Kxd2 {22. Kxd2 After this trade, I have opened up the first rank, to allow my Rooks freedom of movement, in case Black decides to launch an attack on the Queen-side.} 22... Bd6 {22... Bd6 Even though my 21. Ne2 attacks the e-pawn (with my Bishop on b2), I would have assumed Black would play Bxe4, since my d-pawn is pinned against my King. It would be a trade of pawns, but I preferred what Black played.} 23. Ke3 {23. Ke3 Removes further pinning of the d-pawn against my King. I know the king on the 3rd rank is usually a bad idea, but I can follow that Black's Bishops have absolutely no power to threaten any type of check.} 23... b5 {23... b5 This move caught me off guard. If I ignored it, and Black plays 24... bxc4, then I must recapture with 25. dxc4, it destroys my pawn structure, and Black has both Rooks commanding the open files. I must capture it now, which allows Black to regain his pawn structure.} 24. cxb5 Rxb5 {24... Rxb5 Black choses not to restructure his pawns, but to command both open files with his Rooks.} 25. Rb1 {25. Rb1 This is my first tactical mistake - I pinned my own Bishop! However, this opens up a few trades, and opens the board enough to allow my Rook to capitalize on Black's horrible King side position.} 25... Rdb8 {25... Rdb8 Black takes advantage of my tactical error.} 26. Bxe5 {26. Bxe5 Trying to make the most of my mistake, I play Bxe5 anticipating 26... Rxb1 27. Rxb1 Rxb1 28. Bxd6, in which I lose a Rook for a Bishop and a Pawn. This means I am only down 1 point, and am attacking Black's unprotected c-pawn, which I know will force Maim to play 28... Rb5 (most computers do everything in their power to save hung pawns), which releaves me of any immediate threats from Black's Rook.} 26... Bxe5 {26... Bxe5 Because of this play, I can now trade Rooks, and I have only lost a Bishop for a pawn. This is not so bad, since Black's light-squared Bishop is useless. I essentially am even with Black for useful material.} 27. Rxb5 Rxb5 {27... Rxb5 This move was surprising. I know that Maim understands Rooks commanding open and half-open files are good, but it also knows that 3 isolated pawns, and doubled pawns are very bad. For some reason it thought the Rook's power was more important. Chessmaster 8000 and Crafty 19 both believe cxb5 was the better move. This may have been the move that lost the game for Black, although it may already be lost by this time due to its King-side.} 28. f4 {28. f4 Now that Black's e-pawn is gone, I can cramp Black's King-side position even more.} 28... Bd6 29. f5 {29. f5 This move forces the Bishop onto h7, rendering it completely useless.} 29... Bh7 30. Rg1 {30. Rg1 If black does nothing, I will play 31. g6. After an exchange of pawns, I win his Bishop. This move puts more pressure on Black's King-side.} 30... g6 31. f6 {31. f6 Black's King can only move along the back rank. If my Rook can get up there, it is mate, unless a piece blocks it. Black's King and Bishop are completely trapped.} 31... Rb2 {31... Rb2 Black can win one of my pawns.} 32. c3 {32. c3 Since Black is going to win one of the pawns, I choose for it to be the a-pawn. Even though this gives him a passed pawn, it is far from the queening square. Keeping the remaining pawns protected is easier with my c-pawn. A lone a-pawn will be an easy target, and will use up another piece to protect it.} 32... Rxa2 33. Rb1 {33. Rb1 Threatens a mate which can only be stopped by the Bishop moving to f8, which will pin it. This effectively renders this Bishop useless, as well. This also has the threat of gobbling up the Queen-side pawns.} 33... Bf8 {33... Bf8 Stops the check threat of Rb8+.} 34. Rb7 {34. Rb7 En route to Rc7 to capture the c-pawns. The reason this move is preferred to 34. Rb8 is because it attacks the a-pawn. This forces Black's Rook to stay on the a-file while I get another move.} 34... Ra1 {34... Ra1 Threatens Rh1 to attack the h-pawn, while protecting the a-pawn.} 35. Rc7 {35. Rc7 I know Black is going to get my h-pawn, but I do not care. Because it needs to get rid of my g-pawn, and then move its g-pawn, before it can move its Bishop. By the time it gets all this done, I will have caused significant damage. I will capture one of Black's c-pawns next move.} 35... Rh1 36. Rxc6 Rh3+ {36... Rh3+ A useless check like this is a typical computer move as it pushes anything bad it sees in the search beyond the search horizon. This is usually an indication that the computer is losing, since it would not delay a winning position.} 37. Kd2 {37. Kd2 The only move that protects my d-pawn. I could not move to f4, anyway, since Black would play 37... Rxh4+ and get another move.} 37... Rxh4 38. Ng1 {38. Ng1 With the anticipation of 38... Rg4 39. Nf3 which protects the g-pawn, which gives me another move, and allows 40. Ne5 ... 41. Nd7 which attacks the Bishop on f8. 42. Rc8 threatens the bishop, and mate.} 38... Rg4 39. Nf3 {39. Nf3 As expected. Protects the g-pawn, en route to the d7 square.} 39... Rg2+ 40. Ke3 Ra2 {40... Ra2 This was a bad move by Black. Rb2 would have been better to allow the Rook to get into the action once White's Knight gets up there.} 41. Ne5 Rg2 42. Nd7 {42. Nd7 With anticipation of 42... Rxg5 43. Nxf8. If King recaptures, 44. Rc8++ checkmate.} 42... Rg3+ {42... Rg3+ Another delay move to push bad things beyond the search horizon.} 43. Kd2 Rg2+ 44. Kd1 {44. Kd1 Black is going to keep checking me until I get out of the way, so I am going to move to the b3 square. It did not matter if I played Kd1 or Kc1 here.} 44... Rg1+ 45. Kc2 Rg2+ 46. Kb3 {46. Kb3 Black can no longer check.} 46... Rxg5 47. Rc8 {47. Rc8 I could have played 47. Nxf8, but I am going to play it next move, anyway. The order does not really matter, unless I wish to capture both Bishops, in which 47. Rc8 allows Black to move his King, and then his light squared Bishop to save it from a trade. I had no intention to lose my good Knight for his bad Bishop, though.} 47... Kh8 {47... Kh8 Black's only move to prevent mate.} 48. Nxf8 Bg8 {48... Bg8 Prevents discovered check, and will be required to prevent mate in the next move if it is not played now.} 49. Ne6 {49. Ne6 Attacks Black's Rook and double attacks the c-pawn. If Black captures with 49... fxe6, I can answer with 50. f7. The Bishop is pinned, so it cannot recapture or move. The next move is 51. fxg8=Q++ checkmate.} 49... Rg1 50. Nd8 {50. Nd8 Pointless move, as I was attempting to capture the f-pawn, but it is refuted easily by moving the King to release the Bishop from the pin.} 50... Kh7 51. Rxc5 {51. Rxc5 Gives White 2 connected passed pawns, although White now has to worry about the h-pawn. It is 4 squares away from being a Queen.} 51... Rb1+ 52. Kc2 {52. Kc2 I thought a long time about this move. Ka2 was my other choice. Either forces the Rook to move, however I did not want the King in the a-file to be in the way of the a-pawn when my Rook is eventually on the 1st rank, to prevent either the a- or h-pawn from Queening.} 52... Rf1 53. e5 {53. e5 Protects the f-pawn, and opens up the 4th rank to allow the White's Rook access to the h-pawn. This delays its advance for yet another move while improving White's position.} 53... Rf2+ {53. Rf2+ I assume this move pushes the inevitable loss for Black outside of the search horizon. But this worsens Black's position, as it allows the White King to get even closer to the h1 Queening square for the h-pawn. I will take full advantage of these shortcomings of chess programs.} 54. Kd1 {54. Kd1 Getting closer to the h1 square.} 54... Rf3 55. Ke2 {55. Ke2 Protects the d-pawn, gets even closer to the h1 square, and attacks the Rook.} 55... Rf5 {55... Rf5 Prevents 56. e6, since Black will win the Rook if White plays this.} 56. Nc6 {56. Nc6 Protects the e-pawn, attacks the hung a-pawn, and allows the White's Rook freedom of movement. I anticipate 56... h4 57. Ra5 h3 58. Ra1 h2 59. Rh1 blocking the Queening square.} 56... h4 57. Ra5 h3 58. Ra1 h2 59. Rh1 {59. Rh1 All moves as expected. This move blocks the Queen rather than just attacking the Queening square. If I did not move here, and Black eventually got his Rook to g1, I would be forced to trade Rooks, and Black Queens his pawn.} 59... Rh5 {59... Rh5 As expected. The computer will never let a pawn go for free if it can protect it. This allows me to advance my passed pawns.} 60. d4 {60. d4 The White King can do nothing to kill the h-pawn due to perpetual check by the Black Rook. Even if the King goes up and attacks the Black Rook, it can always move to h5 where the King cannot capture it, and it protects the h-pawn.} 60... a6 {60... a6 I can only assume the computer is trying to minimize its losses by saving the a-pawn from immediate capture. This only worsens Black's position, as I will advance my pawns further.} 61. d5 {61. d5 There is nothing black can do to stop me from Queening. The King protects the d3 square, the c-pawn protects the d4 square, and the Knight protects the e-pawn. The Black Rook is trapped from being involved. The game is over.} 61... g5 {61... g5 This move is too late. I will get the Queen and check the Black King before he gets a chance to Queen either pawn.} 62. d6 {62. d6 Chessmaster 8000 analysis, with 1MB hash tables, after 58 min 52 sec, depth 14, 752,576,212 positions: score = 15.97 62. d6 Rh4 63. d7 Kg6 64.

KxRf3} 62... g4 {62... g4 This is Black's last mistake, although the game is already over. Rh4 would have delayed the mate far enough that it cannot be seen in deep computer analysis (although the position is still lost). From here on, we both play perfect play all the way to the mate 10 moves later. Chessmaster 8000 sees the win by the same line of play that we played: in 1 minute, 1 second, depth 11, score 99.77.} 63. d7 g3 64. d8=Q g2 {64... g2 One move too late.

The King's Pawn opening move is both popular and logical. It controls the center, opens lines for both the Queen and the Bishop, and usually leads to an open game in which tactics, rather than slow maneuvering, predominates.} 1... e5 {C20 King's Pawn Game. Black responds symmetrically, making a direct challenge to the central squares.} 2. Nf3 {C40 King's Knight Opening.
