Tournament Chess is a timed game. You can be winning on the board but lose if you run out of time. On the Internet Chess Club hundreds of people from all over the world play chess 24 hours a day, you can always find a game there. Grandmasters, International Masters and the rest of us play there every day. You will even find my friend Igor Ivanov (The picture is from the U.S. Championship) Igor's handle at ICC is IgorIvanov, my online name is (surprise) onegoodmove.
The Benko Gambit is a defense to White's opening move d4 it's popular with players who hate defending and would rather attack. In exchange for a pawn black gets open files and a lot of pressure on the h8-a1 diagonal. Players of the Black pieces also like the fact that they can play the first dozen moves without paying much attention to what their opponent is doing. This can be useful if you have problems with time trouble. On the other hand ignoring your opponent can have deadly consequences as an opponent of mine discovered. This game had a time control of 3-0 that means that each player had to complete all his moves in 3 minutes. The line I play here is very aggressive and Black has to be very careful. (update) I've included an additional eight examples from games I played on ICC. If you're interested in learning more about the Internet Chess Club just click on the link for more information.
