Simon Williams became a IM in 1998 and a GM in 2008. For the last 15 years he has concentrated on teaching, playing and making instructional chess DVDs. He also has a lot of experience commentating about chess including at high-class open tournaments like, Gibraltar and Reykjavik and his own live streams. Williams is the author of numerous chess books. His first book, 'Play the Classical Dutch' was voted, in New in Chess, as one of the top 10 chess books of all time. His playing style is very aggressive, preferring attacking chess to positional grinds, which is one reason why he is perfect for DVDs on the Kings Gambit and Amazing Moves! He has a few impressive personal results, including wins over Magnus Carlsen and Boris Gelfand (just after he was in the World Championship). Two of his students finished 3rd and 5th in the World Junior Championships

In this App, he explains the Londen System in detail.
