Who is Derek Wang?
Derek Wang, known on the board as certai, is a National Master with an unusually patient relationship with the game. He has lived through more than 9,500 online games, and he has learned that a streak is just a streak until it is a record. His longest winning run is 23 games, current run 8, and he keeps going even after a 10 game dip.
His home time control is Daily chess, and he uses that slower pace with a cold deviousness. In 912 Daily games he has scored 645 wins. The quiet time lets him outlast almost everyone who thinks a fast mouse can hide weak preparation.
Opening fingerprint
When Derek has the white pieces, the Réti Opening is a serious favorite. The numbers love it across every time control. As Black he lives inside the Sicilian Defense, especially the Alapin Variation and the Taimanov Variation. He also keeps the King's Indian Defense in the trunk when someone tries to squish him with 1.d4.
