3.c3 is called the delayed Alapin - a nice "trick" against the dragon. Just remember-once you start playing stronger opponents, they aren't going to fall for it.

Very nice, thank you.  I've seen the final tactic in the Tactics Trainer a few times but never knew how it was set up.

1.e4 is as common as it gets if you ask me

1.e4 is the most common way to start a game. Lol.

This tactic is also common in the Trompowsky and several other openings.
