A few notable players that are participating include Muhammad Izz, Camelia Johari, Andrew Soong Loo Yong, Gabriel Soong Mun Hey, Hew Zhenjing, and Muhammad Faris b Aminuddin (the son of an office colleague). There were 25 players registered for the under-20 2nd KL Junior Chess Championship 2010 of which 15 have National Ratings and I think a few of them even have FIDE ratings to their credit. A few that do have FIDE Ratings for sure are Camelia Johari and Muhammad Izz.
The following tables are the results of rounds 1-3, pairings for round 4 and the ranking after round 3 :-
