early queen development

I have just begun playing chess regularly for the past few weeks.  One of the first "rules" I learned was not to develop your queen too early.  In live chess I play people who constantly play 1) e4... c5 2) Bc6 ... Nf6 3) Qf3   My play of Nf6 is because I know the queen is coming next.  Any ideas as to how to stop this irritating white opening?

Just defend the checkmate threat by taking control over the center.

Try 3... e6 followed by 4... d5 or 4... Nc6

Andrew, I think you meant that White plays 2. Bc4. After three minutes of thinking from the position after 1. e4 c5 2. Bc4 Nf6 3. Qf3, which you gave, my Sigma Chess HIARCS 12.1 MP (which supposedly plays at Elo 2950 on my computer) came up with:

3... e6 4. e5 d5 5. Bb5 Bd7 6. Be2 Ng8

which it scored as about a half-pawn advantage for Black, believe it or not. But, actually, HIARCS would have you play 2...Nc6, and then after 3. Qf3:

3... e6 4. Ne2 Nf6 5. Bb3 d5 6. Nbc3 d4

which it scored about the same.

I know.  Computers cannot be trusted in the opening.  Fritz likes to play 1. Nc6 in response to e4.

thanks for the responces folks. nimbleswitch, I did mean Bc4 attacking the weak f7 pawn.  does this change the outcome?

ahill713, I don't think 1.e4 c5 2.Bc4 Nf6 is a good idea for you, because you invite e4-e5. Play becomes sharp, probably better for White. Besides, you block your f-pawn.

How about, 1.e4 c5 2.Bc4 Nc6. Your knight is well-placed on c6. It gets on with development, asserts your control of the central dark squares, is hard to kick, and doesn't prevent any pawns from advancing in the future.

If 3.Qf3?!, you spring the trap 3...Ne5!? and win the bishop pair, and after this simplification you're unlikely to fall into any quick mates. :)

Nope. We all were assuming you meant 2. Bc4 all along. This is a variation on the old Scholar's Mate.
