2. Jiang-Scoones: 22…..Re8! 23 Kf1 f4 with a clear edge for black.

 

3. Patterson-Berry: 17…..bc 18. bc Nd4!? Not conclusive and probably not best but must be analyzed. 19. cd Bd4+ 18. Nf2? (Kh1 looks dangerous because of Ng3+ but is in fact OK for white.

7. Pechisker-Patterson: Black missed 20…..Ng4! with advantage.
