Playing style

As a young player, So's aggressive and tactical style of play caught the attention of a former Philippine chess champion, International Master Rodolfo Tan Cardoso. Cardoso said of So:

"The young lad...would sacrifice a queen or any other pieces in his arsenal to get a winning attack....He cannot afford decent training given by well known GM-coaches and has to rely on his pure talent...before competing."

So commented during an interview with Alina l'Ami in 2009:

"So far I play aggressively. I would like to play a solid game with a solid opening. This is what I want. I think my style is close to Vishy Anand. Of course we have different level."
