Yes, they sell tonics for this type of thing (grin). But yeah, with blitz, especially online, it can be done. Learn a lot of traps. A lot of openings. A lot of tactics. You'll be rising like dough in the oven. Good luck.
**Note
These don't have to be expert traps. Meet some good blitz players out there and they'll be willing to trade some secrets -- traps solid enough to earn you a win with blitz controls.
It's a lot easier to go from 2000 to 1500 instead.
Just saying.
