In Open B I recovered from a disastrous start to end on a respectable 50%, the highest placed senior, so after a final round five hour struggle I was able to make the long drive back to Denmark reasonably contented.
The playing conditions and the atmosphere both inside and outside the playing hall were tremendous. In the boisterous and social chess cafe I was lucky to meet who showed me and others how she won her endgame against IM Twan Burg. She brilliantly sacrificed a bishop to open files for her rooks to create a mating net. This was very inspiring and instructive.
Peng was also willing to analyse one of my games and to share words of chess wisdom, for which I am very grateful. Anatoly Karpov was an interested spectator to her game against Burg. Was he also visualising the endgame?
By playing 54...Kf6, Black is putting himself into a zugzwang situation and his king is also cut off. Finally she found a nice idea: a piece sacrifice in an attempt to create checkmate.
