|Nov-08-18|| ||HeMateMe: looks like this eliminates Irina. The game seemed equal after 13 moves but white get better king position in the endgame. Wenjun is rated 150 points higher than Krush, a difficult opponent. A good endgame to study, play it against an engine as a training exercise.|

|Nov-11-18|| ||Jonathan Sarfati: Some excellent technique from Ju here, the sort of win one would expect from Magnus Carlsen or Jose Raul Capablanca. This game is one example of how some of the advice in chess books is not really so good: namely the queen-side majority. It is not usually the only factor in a lot of games, even when the side with it wins, and in many games it's not a factor at all. The most important things are relative mobilities of the rival majorities, and activity of the rooks. Here, even the open file was not important because all entry squares were controlled. Just the very quick K-side Ps.|
Krush was criticised for 37... fxg5, and the computer doesn't like it as much. But when it continues with allowing White to play g6, Black soon gets in a bad way. Black must choose between leaving the K where it is, but then the R gets tied to the Pg7 and White will be able to push e5 and get a strong advanced passed P. But if Black defends with the K on g8, then it's subject to back rank mate threats, and if Black covers that rank with his R, then White gets her R to d7.
Often the K-side majority is really a central majority, which can seize space and drive pieces away from important posts. Against the gallant but heavily ourtated Australian rep (Ju Wenjun vs Kathryn Hardegen, 2018), Ju had a very similar P structure but used the centre to drive a N away from protecting the seventh rank.
|Nov-25-18|| ||RookFile: I think 25... Kd8 was too passive. Kd7 instead at least has an idea of marching the king towards the center, although white can prevent that. Because black could not bring the king to the center, white had a free hand on the kingside.|
