Valneris - Dul 2-0
Valneris - Dul 2-0

35-40! Black must sacrifice a piece, since   21-27? fails due to 49.33-28 23x32 50.44-40 35x33 51.38x9.   49.44x35 21-27? Under pressure of time Dul does not find   23-29! 50.42-37 21-27! 51.33-28 27-31 52.28-22 31x44 53.22x13 19x8 54.30x10 with a draw.   50.39-34 17-22 51.34-29 23x34 52.30x39 27-31 53.26x37 22-27 54.33-28 18-23 55.37-32 27-31 56.32-27

Seck - Getmanski 1-1
Seck - Getmanski 1-1

Getmanski missed a simple combination: 18-22! 54.27x18 13x22 55.24x4 22-27 56.32x21 16x27 57.4x31 26x46 and black wins.   19-23? 54.41-37 11-17 55.27-21 16x27 56.32x12 18x7 57.37-32 13-18 58.38-33 18-22 59.33-29 22-28 60.29x18 28x37 61.24-19 37-42 62.19-13 9-14 63.13-8 42-48 64.8-2 14-20 65.2x16 20-24 66.30x19 48x22 67.16-27

van der Wijk - Chizhov 1-1
Wijk - Chizhov 1-1

35.48-43? 1-6? Here Chizhov could have gained a winning advantage using   9-14! An important clue is that after 36.30-25 7-12 white cannot proceed with 37.27-22? due to 24-30! 38.22x11 20-24 39.25x34 24-29 40.33x24 19x48 41.28x17 48x8. But other possibilities are failing as well, for example   37.31-26 12-18! 38.43-39 3-9! 39.40-34 24-30 40.35x24 20x40 41.45x34 15-20 B+ or   37.43-39 12-18 38.40-34 24-30 39.35x24 20x40 40.45x34 3-9! 41.34-30 23-29 42.33x24 15-20 43.24x15 18-22 44.27x18 13x42 B+. If white plays immediately   36.31-26 then black continues with 7-12 37.27-21 12-18! 38.21x12 18x7 and now for example 39.43-39 1-6! 40.30-25 3-8 41.26-21 8-12 and 42.40-34 6-11 43.21-16 11-17 44.34-30 12-18 45.39-34 18-22 B+   36.31-26 7-12 37.30-25 13-18 38.25x14 9x20 39.27-22 18x27 40.32x21 23x32 41.38x27 3-8 42.43-39 8-13 43.39-34 6-11 44.21-16 13-18 45.16x7 12x1 46.34-30 18-23 47.30-25 1-7 48.25x14 19x10 49.40-34 7-12 50.27-21 12-18 51.21x12 18x7 52.26-21 10-14 53.34-30 24-29 54.33x24 14-20 55.45-40 20x29 56.40-34 29x40 57.35x44 15-20 58.44-39 23-28 59.30-25 20-24 60.39-34 28-32 61.34-29 24x33 62.25-20 33-39 63.20-14 39-44 64.14-10 44-50 65.10-5 32-38 66.5-23 7-11 67.23-14

Ndjofang - Georgiev 1-1
Ndjofang - Georgiev 1-1

Georgiev made a severe miscalculation with 19-24? 38.20x29 32-37 39.39-34(?) More precise is   39.29-23   9-13 40.34-30 8-12 41.33-28! 22x42 42.43-38 42x24 43.30x10 27-31 44.36x27 37-41 45.10-4 3-9 46.4-15! 41-46 47.15-33! 46-23 48.33x6 23-45? 49.6-50(?) 12-18? 50.25-20! 9-14 51.20x9 13x4 52.35-30 18-23 53.27-22? The players were still playing quickly, seemingly unaware that the 50 moves were already finished. According to the computer   53.30-25 was winning here.   45-40 54.22-17 23-28! 55.50x22 16-21! Now a draw is inevitable. 56.30-25 21x12 57.22-50 40-23 58.50-44 4-10
