⚪️Radjabov,Teimour (2751)
⚫️So,Wesley (2776)
🔸1-0

27...Rd8?
Wesley's carelessness that fully is exploited by Radjabov.
The correct continuation is 27...axb5 28. axb5 Re8.
28.bxa6 Bc8

44.b4!
Idani makes a powerful passed pawn on the a-file.
44...axb4 45.a5 Bg5
45...Bxh2!!
An amazing way to draw the game.

⚪️Kramnik,Vladimir (2779)
⚫️Aleksandrov,Aleksej (2602)
🔸1-0

24.Nxd5!!
In this position, White is practically a piece up due to the black terrible bishop on g6. Kramnik correctly opens up the position.
24...cxd5 25.Rb6+ Kd7 26.Bf1!
Threaten checkmate in three.
26...Kd8 27.Bb5 Re4 28.Rxb7 Nf6 29.b4!
Now, threatening to create a passed pawn on the a-file, makes things even harder for Black.
