GAME 1 - Novel opening play from Komodo leads to quick equality.

Opening line used:
1. e4 d5 2. exd5 Qxd5 3. Nc3 Qa5 4. Nge2

I feared for Komodo after it played 6....Nc6, as normally in a Qa5 Scandinavian, the pawn goes to c6 to allow a retreat for the queen. However, the Be6-Bc4 manouevre was good enough to gain equality. After the queens came off, an interesting middlegame followed in which Stockfish initially had a tiny advantage due to its better mobility and the semi-open c-file. Clever defensive play from Komodo was able to turn the tiny advantage around in its favour, but despite being able to win a pawn in the endgame, the result was always going to be a draw.

GAME 2 - Stockfish exchange sac defuses kingside danger.

Opening line used:
1. e4 d5 2. exd5 Qxd5 3. Nc3 Qa5 4. Nge2

The opening in this game was played in a more classical manner by Stockfish, but led to its having a more passive position. Komodo looked as though it might be able to create some problems on the kingside, but a clever exchange sac from Stockfish quickly defused any danger. Due to the power of the black bishop pair, Komodo had to give back the exchange, and the resulting endgame, although tricky, was destined to be another draw.

GAME 3 - Komodo endgame error leads to defeat.

Opening line used:
1. c4 e5 2. g3 c6 3. Nc3 f5 4. d4 d6 5. Bg2 Be7 6. e3 Nf6 7. Nge2 e4

Komodo's 10...g5 was like waving a red flag at a bull. Stockfish immediately started out for the jugular with 13.h4, opting to castle queenside into the face of a counter-attack. As you'd expect, an intriguing middlegame followed, but neither attack proved decisive. The double rooks endgame that eventuated seemed fairly harmless, but it would appear that Komodo erred with 38...d5. After that, Stockfish always felt that it was winning and was indeed able to eke out victory. So Stockfish strikes first to take a 2.0-1.0 lead in the match.

GAME 4 - Komodo queenside pressure met with resourceful kingside counterplay.

Opening line used:
1. c4 e5 2. g3 c6 3. Nc3 f5 4. d4 d6 5. Bg2 Be7 6. e3 Nf6 7. Nge2 e4

As white, Komodo began building up pressure on the queenside and was becoming increasingly happy. It was seemingly just a case of which pawn push would be the one. However, once the decision was made, Stockfish immediately countered on the kingside in what turned out to be both a resourceful and effective manner, with 25...Qf6! being a key move. Although there was still plenty of interest and play to come, both sides soon realised that there was nothing to be gained, and the game eventually ended in a draw. Stockfish leads the match by 2.5-1.5.

GAME 5 - Plenty of activity, but both sides evaluate 0.00 for the entire game!

Opening line used:
1. c4 e5 2. g3 c6 3. Nc3 f5 4. d4 d6 5. Bg2 Be7 6. e4 Nf6 7. dxe5 dxe5 8. Qxd8+ Bxd8

Despite a prolonged period of tactics and exchanges straight out of the opening, I think that this is the only game I've ever recalled playing where the evaluation for both sides was 0.00 throughout the entire game!

GAME 6 - Opposite side castling, but no advantage to be gained.

Opening line used:
1. c4 e5 2. g3 c6 3. Nc3 f5 4. d4 d6 5. Bg2 Be7 6. e4 Nf6 7. dxe5 dxe5 8. Qxd8+ Bxd8

As Black, Stockfish opted to castle long to try and maintain a grip on the centre. However, there was nothing to be gained as Komodo easily maintained equality into the endgame. Stockfish leads the match by 3.5-2.5.

GAME 7 - Stockfish attempts to inject life into the game are thwarted.

Opening line used:
1. c4 e5 2. g3 c6 3. Nc3 f5 4. d4 d6 5. Bg2 Be7 6. e4 Nf6 7. exf5 exd4 8. Qxd4 Bxf5

Stockfish was happy early on, but Komodo was able to show that there were no gremlins in the position. With 22.f5 and 23.b4, Stockfish attempted to inject life into the game, but to no avail. Komodo's passed d-pawn (which could be viewed as either a weakness or a strength) gave itself up for the white h-pawn, and the resulting endgame was dead equal.

1/2-1/2[/pgn]

GAME 8 - Stockfish plans fail to achieve any advantage, as Komodo holds equality throughout.

Opening line used:
1. c4 e5 2. g3 c6 3. Nc3 f5 4. d4 d6 5. Bg2 Be7 6. e4 Nf6 7. exf5 exd4 8. Qxd4 Bxf5

As black, Stockfish chose to keep its bishop pair and create a passed c-pawn. When it became clear that there was nothing to be gained from that decision, Stockfish sacced the exchange with 44...Rxf4 to open up Komodo's kingside. However, with so little material left, that plan failed to gain anything either, and the eventual endgame was drawn. Stockfish leads the match by 4.5-3.5.

GAME 9 - Kingside threats lead to decisive gains elsewhere for Stockfish.

Opening line used:
1. e4 g6 2. d4 d6 3. f3 Nf6 4. c4 Bg7 5. Be3 c6 6. Nc3 O-O 7. Bd3 Nbd7

Stockfish loved this line as white, as it was able to use threats on the kingside to breakthrough in the centre and win material. Whereas the move 25.Nd5 was pleasant on the eye, it was the quiet move 28.b4 which was the killer. A second win to Stockfish sees it leading by 5.5-3.5.

GAME 10 - Back to back wins extend Stockfish lead to 6.5-3.5.

Opening line used:
1. e4 g6 2. d4 d6 3. f3 Nf6 4. c4 Bg7 5. Be3 c6 6. Nc3 O-O 7. Bd3 Nbd7

As white, Komodo preferred to look to queenside play for an advantage, but Stockfish was able to launch a kingside pawn storm. Seemingly oblivious to the pending danger, Komodo could likely have forced a repetition with starting with 25.Nc7, but still felt that it had an advantage. The tide began to turn with 37...Nc7, as Stockfish ignored the loss of queenside pawns to push on with its kingside attack. With Komodo's pieces tied to defence, 54...e4 was the killer move for Stockfish. Stockfish now has a 6.5-3.5 lead, and with three wins on the board, is halfway there toeards winning the match.

GAME 11 - Early endgame leads to expected draw.

Opening line used:
1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. Bd2 Bg7 6. e4 Nb6 7. Be3 O-O 8. h3 e5 9. Nf3 exd4 10. Nxd4

As black, Komodo was hoping to take early advantage of the white king still looking to castle. However, Stockfish was soon to castle long with equality. The pieces started coming off quite quickly, leading to an early endgame. This failed to change the outcome though, which both sides always regarded as level.

GAME 12 - Some spectacular fireworks only lead to a draw.

Opening line used:
1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. Bd2 Bg7 6. e4 Nb6 7. Be3 O-O 8. h3 e5 9. Nf3 exd4 10. Nxd4

The return game followed a different path, as Komodo was prepared to ignore the possible loss of the e4 pawn in order to castle kingside. A complex sequence of tactics followed, and after the smoke had cleared, Komodo came out with queen, bishop and two extra pawns against rook and three minor pieces. Despite all of the fireworks, both sides considered the position as 0.00 from move 25 on, and Stockfish quickly took a repetition of moves. Stockfish leads the match by 7.5-4.5.

GAME 13 - Stockfish pawn thrusts seal a memorable win.

Opening line used:
1. Nf3 Nf6 2. c4 b6 3. d4 e6 4. Bf4 Bb7 5. e3 Be7 6. h3 c5 7. dxc5 bxc5 8. Be2 Qb6 9. Nc3 O-O 10. Qc2 Rd8

This game was going nowhere in a hurry, as both sides undertook a prolonged period of manoeuvering. Then Stockfish struck with 38.b5 to change the face of the game. However, it was the clever follow-up exchange sac 44.Rxc3 that cemented connected passers on the a and b files, which turned out to be the decisive factor. Komodo returned the material to eliminate those two pawns, only to face the knife thrust 69.f5. Stockfish achieves its fourth win in the match and now leads by 8.5-4.5.

GAME 14 - An interesting game, but an eventual draw.

Opening line used:
1. Nf3 Nf6 2. c4 b6 3. d4 e6 4. Bf4 Bb7 5. e3 Be7 6. h3 c5 7. dxc5 bxc5 8. Be2 Qb6 9. Nc3 O-O 10. Qc2 Rd8

As black, Stockfish opened the queenside up early, and eventually ended up with a passed a-pawn.This didn't prove to be a threat though, and Komodo still considered itself to have an edge. The a-pawn was eliminated and then Komodo pressure on the kingside led to the win of a pawn. However the rook and pawn ending was a clear draw. Stockfish leads by 9.0-5.0.

Thanks Graham for the games and especially the commentary.

GAME 15 - Tricky play on the queenside, but eventual equality.

Opening line used:
1. d4 Nf6 2. c4 g6 3. g3 c5 4. Nf3 cxd4 5. Nxd4 d5 6. Bg2 Bg7 7. O-O O-O 8. cxd5 Nxd5 9. Nc3 Nb6

Following the opening, Stockfish set its sights on the black queenside, and things looked quite tricky for a while. Komodo was able to fully equalise though with the unexpected 19...Nd4, taking advantage of the knight on a7, and choosing to give up a pawn in the process. However Stockfish had no chance of taking advantage of the queenside pawn majority due to the power of Komodo's bishop pair. An endgame eventually resulted with opposite coloured bishops, and this was obviously drawn.

GAME 16 - Interesting game with tiny swings of fortune, but another draw.

Opening line used:
1. d4 Nf6 2. c4 g6 3. g3 c5 4. Nf3 cxd4 5. Nxd4 d5 6. Bg2 Bg7 7. O-O O-O 8. cxd5 Nxd5 9. Nc3 Nb6

Play again centred on the queenside initially, with Stockfish taking the opportunity to create doubled pawns on the e-file. With the follow-up pawn sac 17...e4, Stockfish then tried to take advantage of the pawn weakness, but Komodo was able to hold firm and even achieved a tiny edge. However, any advantage was purely illusory, even after Komodo sacced the exchange for a couple of extra pawns. Another draw and Stockfish leads by 10.0-6.0.

GAME 17 - Stockfish creates an advantage on the queenside, then makes the decisive breakthrough on the other flank.

Opening line used:
1. b4 Nf6 2. Nf3 c6 3. c4 g6

Stockfish used a pawn front on the queenside to establish a spatial advantage, while Komodo's attempted counter on the kingside came to nought. Instead it was Stockfish, that having locked up a queenside, paved the way for a winning advantage with 35.f3. The white rooks doubling up on the f-file saw Stockfish infiltrating on the kingside. Komodo fought doggedly, but once the queens were exchanged, white's remaining rook gobbled up some pawns and it was all over. Stockfish is now just one win away from match victory at 11.0-6.0.

1-0[/pgn]

GAME 18 - Stockfish negates possible queenside squeeze with 4...a5, leading to an equal game.

Opening line used:
1. b4 Nf6 2. Nf3 c6 3. c4 g6

As black, Stockfish took immediate steps to counter the possibilty of a queenside squeeze, with 4...a5. As a result, Komodo was unable to create any threats and the position was effectively equal. After the major pieces came off along the c-file, the resulting endgame was always going to end in a draw. Stockfish leads by 11.5-6.5.

1/2-1/2[/pgn]

GAME 19 - Long tactical sequence initiated by Stockfish leads to queenside pawn majority in endgame, but Komodo prevents progress.

Opening line used:
1. c4 b6 2. d4 e6 3. a3 f5 4. Nf3 Nf6 5. g3 Bb7 6. Nc3 Ne4 7. Nxe4 Bxe4 8. Bh3 Be7 9. O-O O-O 10. d5 Qe8

Following the opening line, Stockfish opted for a tactical continuation that won the exchange, albeit temporarily. Once that Komodo had regained the material, a rook and pawn ending arose in which Stockfish had a queenside pawn majority. However, there was no advantage to be gained as Komodo's king took control of the centre, thus preventing any further progress.

GAME 20 - Komodo opts for a quieter approach with an eventual drawn ending.

Opening line used:
1. c4 b6 2. d4 e6 3. a3 f5 4. Nf3 Nf6 5. g3 Bb7 6. Nc3 Ne4 7. Nxe4 Bxe4 8. Bh3 Be7 9. O-O O-O 10. d5 Qe8

Komodo opted for a quieter approach, focusing on central control. Stockfish tried to counter on the kingside without success, and following several exchanges, a queen and pawns ending resulted which was clearly drawn. Stockfish leads by 12.5-7.5 (five wins to zero).

GAME 21 - Komodo holds Stockfish at bay for another draw.

Opening line used:
1. e4 e5 2. Bc4 Nf6 3. d3 h6 4. Nf3 c6 5. O-O d6 6. a4

It looked as though Stockfish might initially be looking for an advantage on the queenside, but it quickly became apparent that nothing much was on offer there. After getting a rook on the seventh rank, Stockfish then tried the speculative 28.Bxh6. However, both sides evaluated the position at 0.00, and that wasn't going to change. An eventual draw resulted.
