World championship 2013 preliminaries round 3

Dul - Schwarzman 1-1
Erdenebileg Dul - Alexander Schwarzman 1-1

After Schwarzman mistakenly played 15-20? Dul reacted with the strong move 42.48-43! But apparently he offered a draw at this moment, not knowing that the position is winning for white. When Schwarzman realized the amount of trouble he was in (6-11? 43.16x7 12x1 44.39-34! 18-23 45.27-22 W+ or   20-24? 43.16-11 17-22 44.39-34 6x17 45.34x32 22x31 46.26x37 W+) he gladly accepted the offer. At that moment there was some discussion about whether or not he had already declined the offer. But in the end he got away with it.

Shaibakov - Berichvili 2-0
Ainur Shaibakov - Djoumber Berichvili 2-0

After 8-12? Shaibakov surprised his opponent with the combination 39.29-23! 18x27 40.15-10! and black did not await 22x44 41.31x2 4x15 42.2x16 anymore.

Lognon - Ndjofang 0-2
Oscar Lognon - Jean-Marc Ndjofang 0-2

Lognon has ended up in a somewhat uncomfortable endgame against Ndjofang. After 51.36-41? 19-24? Black could win at once using the hidden sacrifice   19-23! 52.28x19 15-10!! 53.19-13 10x46 54.13-9 46-14 55.9x20 25x14 etc.   52.41-36 24-30 53.36-4 15-42 54.28-23? 42-37! 55.4-18 37x10 56.18x1 26-31 57.44-40? The situation was already difficult for white, and after this move it is lost. 31-37 58.40-35 10-15 59.35x24 15x49 60.1-29 37-41 61.29-42 49-35
