H@LLINGGOL, substituting the L's and G's for the fancy letters. Notice it's HALLI not HALLE. Anyway, he never plays 2/4.. only 10/20 and 25/50 on stars, possibly just 25/50 now but I really havn't followed those games much of late.

His name is Frederick or Oren, depending on who you ask. It's possible that the first one is his real one and the second one is his nickname but again, not really sure.
