1.e4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.d3 a6 6.Be3 d6 7.Nge2 Rb8 8.Qd2 h5 9.0–0 Bh6 10.Bxh6 Nxh6 11.f4 Ng4 12.h3 Nf6 13.Nd1 0–0 14.Ne3 b5 15.c3 b4 16.e5 dxe5 17.Bxc6 exf4 18.Nxf4 Bb7 19.Bxb7 Rxb7 20.Rae1 Ne4 21.Qg2 f5 22.dxe4 fxe4 23.Qxe4 Rd7 24.Qxg6+ Kh8 25.Qh6+ Kg8 26.Ng6 Rf6 27.Qh8+ Kf7 28.Qxd8 Rxd8 29.Rxf6+ exf6 Now starts an ending where white has two knights. White conspires to draw this ending, which is atrocious even in time trouble of around one second per move. I am interesting in observing how a series - ranging from major to minor - of many errors over many moves in an ending can eventually change the evaluation of the position so much that the result of the game then changes, (I use result in the endgame sense). 30.Nf4 bxc3 31.bxc3 Rd2 The first point where a real plan needs to be made for white. The a2 pawn is hanging. Two knights cannot mate a king so pawn trades should be as few as possible. After taking a2 black has a passer on a6. Knights are very poor at blockading a passer, particularly on the side of the board. This is felt during the game. 32.a4 [for a start, an obvious idea is: 32.Nxh5 white has a passed pawn on the h file. Black's a6 pawn is more powerful though as it is an outside passer (across the board from the kings) and knights are very bad at blocking an a or h pawn. 32...Rxa2 33.Rf1 doubling up on f6.. if f6 falls, white has connected passer on the g-h files] 32...Ra2 33.Nd3 [33.Nf5 fritz puts the evaluation much higher than otherwise for white (although it is obviously many pawns as the position should be totally won). There must be a mate threat as the computer goes mad playing Ra1. Supposing Rxa4.. 33...Rxa4 With a couple of second at most for each move, I didn't see such a mating net.. I was looking for ways of capturing enemy pawns and attempting to trade rooks. 34.Re7+ Kg8 (34...Kf8 35.Ng6+ Kg8 36.Nh6#) 35.Nh6+ Kf8 (35...Kh8 36.Ng6#) 36.Ng6#] 33...Rxa4 34.Nxc5 Ra3 35.Rc1 I am adamant to avoid pawn trades. [35.Nd5 an obvious move, defending with knight and bringing the knight to a more active square, and making the knights more coordinated etc etc 35...a5 36.Rf1] 35...a5 36.Nc4? [36.Nd5 this was again much better 36...a4 37.Rf1] 36...Ra2 37.Nd6+? [37.Rf1 a4 38.Ne4 Kg7 39.Nxf6 h4 40.gxh4] 37...Ke7 38.Nf5+ [38.Rd1 a4 39.Nde4 Kf7 (39...Ra3 40.Rd7+ Kf8 41.Ne6+ Kg8 42.Nxf6+ Kh8 43.Rh7#) 40.Rd7+ Kg6 41.Rd6 Kf5] 38...Kf7 39.c4 [39.Rd1 Kg6 (39...a4 40.Rd7+ Kg8 (40...Kg6 41.Nh4+ Kh6 (41...Kg5 42.Rg7+ Kh6 43.Nf5#) 42.Ne6 Rc2 43.Nf5+ Kg6 44.Ned4 Rc1+ 45.Kf2 Rc2+ 46.Kf3 Rxc3+ 47.Kf4 Rf3+ 48.Nxf3 h4 49.N3xh4+ Kh5 50.Rh7#) 41.Rg7+ Kh8 42.Ne4 Ra1+ 43.Kf2 Ra2+ 44.Ke3 Ra3 45.Nxf6 Rxc3+ 46.Kd4 Rd3+ 47.Kxd3 h4 48.Rh7#) 40.Nh4+ Kh6 41.Ne6 Ra4 42.Rd8 Rxh4 (42...Ra3 43.Rh8#) ] 39...a4 40.Nd6+ [40.Ne4 keeping the knight close to the enemy king for the mate themes etc 40...Ke6 (40...a3 41.c5 Ke6 (41...Rb2 42.Ned6+ Ke6 43.c6 Rb8 44.c7) 42.Ng7+ Ke5 43.c6) 41.Ng7+ Kd7] 40...Ke7 41.Nc8+?! poor move; pointless [41.Nb5; 41.Nde4] 41...Kd8 42.Nb6 a3 43.Nb3? really bad, losing a knight [43.Ne6+ the knights are working together well 43...Ke7 44.c5! this passer is big trouble, whereas black's rook is in no position to promote his own pawn, sitting directly in front of it 44...Kxe6 45.c6 the computer goes beserk here as there is nothing to do 45...Kd6 46.c7 Ra1 47.c8Q] 43...Rb2 44.Nd4? very bad. The remaining knight is poor, whereas after Nd5, the remaining knight is much better [44.Nd5 Rxb3 white's concern is the black pawn on a3.. the knight cannot really help with this 45.Ra1 immediately is inferior to Kg2 as (45.Nxf6?? this is terrible.. black wins the game 45...a2 46.Nxh5 Rb1) 45...Rxg3+ 46.Kf2 Rb3 though black has no way of making threats of promoting the pawn so the position is probably easy for white here] 44...Rxb6 45.Ra1 correct, getting in front of the enemy passer 45...Ra6 46.Nb5? very poor even if the evaluation doesn't drop much.. why allow the a pawn to advance to a2? [the correct move is naturally 46.Ra2 Ra4 47.Nf5 (47.Nb5 looks like a reasonable plan, though now there are just two pawn left on each side so a draw is a greater risk 47...Rxc4 48.Rxa3 I will analyse this position in some depth as it certainly seems an instructive position 48...Kd7 49.Rd3+ Ke7 50.Kf2 Rc2+ 51.Kf3 Kf7 52.Nd4 Rc4 53.Ne2 h4 54.g4 Rc5 55.Nf4 the knight locks itself in with the pawns where it belongs in this sort of position 55...Rb5 56.Rd7+ Ke8 57.Rh7 f5 . (57...Rb3+ 58.Ke4 the knight is defending the h3 pawn) 58.g5 keeping the pawn count to two each (58.gxf5 surely riskier to trade pawns as now the position is more technical with one pawn each on the h file 58...Rxf5 59.Kg4 Rf7 60.Rxf7 Kxf7 61.Kxh4 Kg7 62.Kg5 in this case there is no problem) 58...Rb3+ 59.Ke2 Rb2+ 60.Kd3 Kf8 61.g6 Rb6 62.Kd4 Kg8 63.Rxh4 Rd6+ 64.Ke5 Rd1 the position is resolved) ] 46...Ra4 47.Rxa3? stupid.. let me reiterate that this game was played with a 1 second increment, which I think was roughly how much time I had [obviously 47.Nxa3 defending the c4 pawn] 47...Rxc4 The remaining position must be played with care: two pawns each on the same side of the board, a rook each, and a knight for one side, which at the moment is well offside 48.Ra6 [restricting the black king to his back rank 48.Ra7 h4 49.gxh4 Rxh4 50.Kg2 Rh5 51.Nd4 Ke8 52.Ne6 Re5 53.Ng7+ Kf8 54.h4 Rb5 55.Kf3 Kg8 56.Kg4 Rc5 57.Nf5 Kf8 58.h5 Rc4+ 59.Kf3 Rc3+ 60.Ke4 Rh3 61.h6 Kg8 62.Kd5 Rh2 63.Ke6 Kh8 64.Ra8+ Kh7 65.Kxf6 Rb2 66.Ra7+ Kh8 67.Rf7 Rb6+ 68.Kg5 Rb1 69.Rd7 Rg1+ 70.Kf6 Rb1 71.Rc7 Rb6+ 72.Kg5 Rb5 73.Rd7 Rb2 74.Ne3 Rb1 75.Ng4 Rg1 76.Kf5 Rg2 (76...Rf1+) 77.Ra7 Rg3 78.Nf6 Rf3+ 79.Kg6 Rg3+ 80.Kf7 Ra3! clever trick 81.Rd7 (81.Rc7?? Ra7 draw 82.Ke6 Rxc7 83.Ng4 Kh7 84.Kf6 Rc4 85.Ne3 Rc6+ 86.Kf7 Rxh6 draw(86...Kxh6 draw; 86...Rf6+ 87.Kxf6 Kxh6 draw) ) 81...Rd3 82.Rc7 fritz plays this, and appears to have lost the plot.. 82...Rc3 83.Re7 Rc7 84.Nd7! instead it turns out fritz is playing a flawless endgame manouvre.. see the notes to see why he doesn't play Rc3 right away on move 81 84...Kh7 (84...Rc8 85.Kg6 Rc6+ 86.Nf6 Rxf6+ (86...Ra6 87.Rh7#) 87.Kxf6 Kg8 88.h7+ Kh8 89.Re8+ Kxh7 90.Rf8 Kh6 91.Rh8#) 85.Nf8+ Kxh6 86.Rxc7] 48...Rb4 49.Rxf6? this is a weak decision and I knew it at the time but I probably had to make a move with no time to delay [49.Nd6 Ke7 50.Nf5+ Kf7 51.Ra7+ Kg6 52.Ne7+ Kh6 53.Ra6 Kg7 54.Nd5 Rb1+ 55.Kg2 Rb2+ 56.Kf3 Rb1 57.Ra7+ Kg6 58.Nf4+ Kh6 59.Ra6 Rb3+ 60.Ke4 Rxg3 61.Rxf6+ Kh7 62.Rf5 Rg1 63.Rxh5+ Kg7 64.Kf5 Rf1 65.h4 Rf3 66.Kg4 Re3 67.Rd5 Re1 68.Rd7+ Kh6 69.Rd6+ Kg7 70.Ne6+ Kf7 71.Ng5+ Ke7 72.Ra6 Rg1+ 73.Kf5 Rh1 74.Ra7+ Kd6 75.Rh7 Rf1+ 76.Kg6 Rc1 77.h5 Rc8 78.h6 Kc5 79.Rg7 finally black is forced to sacrifice his rook to prevent the pawn promoting 79...Rc6+ 80.Kh5 Rxh6+] 49...Rxb5 now the position really does take some serious technique to win 50.Kf2 [50.Rf7 fritz immediately prioritises cutting off the black king as much as possible] 50...Ke7 51.Rf4 Ke6 52.Kf3 Rb3+ 53.Kf2?! makes no sense other than to gain time on the clock if that is what white is doing; please don't ask me to remember [53.Kg2 Rb1 54.Rf2 Ke5 55.Rf8 Rb2+ 56.Kg1 Rb3 57.Re8+ Kf5 58.Kg2 h4 59.g4+ Kg5 60.Rh8 Rg3+ 61.Kh2 Rc3 62.Rh5+ Kf4 63.Rf5+ Ke3 64.Kg2 Rc2+ 65.Kg1 Rc1+ 66.Rf1 Rc2 67.Kh1 Rc3 68.Kg2 Rc2+ 69.Kg1 Rd2 70.Kh1 Rd3 71.Kg1 Rd2 draw] 53...Ke5? poor as this gives white a good chance [53...Rb5 54.Kg2] 54.Rf3? misses any chance [54.Rh4!

I don't expect the endgame to be played perfectly in bullet chess, but this was probably the final straw that prompted me to analyse the whole ending [72.Re5+ Kf4 73.Re8] 72...Rg4?? what?? [72...Rxg6+ draw] 73.Kf6 [73.Rf6 avoids threefold repetition 73...Kd3 74.Kf7 and wins] 73...Rg3 draw by threefold repetition. A horrifically played ending from start to finish by both sides, but the analysis has proven interesting. ½–½
