As a young player, his aggressive and tactical style of play caught the attention of former Philippine chess champion, International Master Rodolfo Tan Cardoso. Cardoso said, "The young lad...would sacrifice a queen or any other pieces in his arsenal to get a winning attack." Also, according to Cardoso, "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." He has also said that his favourite game was his win against Ni Hua in the 2008 Chess Olympiad, which was his first win against a 2700-rated opponent.
During So's tournament victory at Bad Wiessee in 2006, he earned a creativity award in the Russian magazine e3e5 for the following game, where he won in spectacular fashion:
