2020 US Chess Championship

 Wesley So won convincingly his second US Champion title.

This was played as a rapid chess ( 25 minutes + 5 seconds) online but still gives him the 2020 US Chess Champion title. While Nakamura participated, Fabiano Caruana wasn't part of the tournament as he was supposed to be in the World Chess Candidates tournament -postponed to 2010-

Lets replay a critical game : So-Xiong 

Wesley So won that game and Jeffery Xiong finished 2nd in the tournament. This also showcases Wesley's style, very solid, few mistakes and converting small edges.

Grand Prix Attack Themes

Here we are presenting useful themes for White.
 Also to note if you are playing these positions with Black, watch for the attacking theme. Main Theme for White against g6,Bg7 and ..d6 or ..c5 : White will try to play Qd1-e1, Kh1, then f4-f5 or Qe1-g3 with strong attack.
 This can arise from Pirc, Sicilian Kan-Taimanov or Grand Prix Attack (B23). Typically White's bishop goes on b3

example 1 : B23 Grand Prix

Example 2: Sicilian Kan
