The Corvallis/Albany Open is Saturday and Sunday, Dec 10-11. The event is designed for any player who is comfortable with long time controls (40/90 SD30 on Saturday, 40/120 SD60 on Sunday). Players rated below 1800 may play in the Reserve Section for prizes totaling $675. If you are rated well below 1800, no problem. There are substantial cash prizes for top finishers in the Reserve section, and there are also prizes for top-scoring U1600 and U1400 players. Several players rated 850-1250 have already registered, and there will certainly be plenty of players 1400-1799 as well. Masters (rated 2200+), Experts (2000-2199), and Class A players (1800-1999) play in the Open section for prizes totaling $675 ($300-200-100 for 1st-3rd and $75 for top U2000).

You can register online or register at the door (although participation is limited to the first 50 paid registrants, so pre-registration is recommended). Entry fee: $40.
