he was trying to scholar mate me

So you were playing black? I think 2...e6 is better than g6, because the c5 pawn is then protected by the bishop:)

Yeah, 8. ... Qd1#. Lucky how things turned out after that, really. But also an example of why you shouldn't try to make the Queen do it all.

2...e6 is better, likely the correct move in that position, actually.
kenible3 is also correct that your opponent had the immediate 8...Qd1#.

9...Nd5?? is a blunder as far as I can tell, throwing away a piece for nothing (assuming accurate followup from you, which you didn't exactly exhibit).
10...Bh5? should lose to g4, trapping the bishop
11.dxc5?? was indeed your game losing blunder that gave your opponent a second chance to checkmate you

Remember the rule of thumb that a tempo is worth 1/4-1/2 a pawn on average (although actually a one tempo difference can often be enough to determine who wins and who loses a game...not usually in the opening phase, however). How many queen moves did you make? I count 5. Which means that your opponent should have had at least enough compensation for the pawn, assuming he used his extra tempi wisely. Considering his lead in development, I'd say he did. Said lead in development was essentially the reason why the mating opportunity arose for him, by the way.

Let this loss be a reminder to you about the value of a lead in development.

i was playing as black you know

then 3. Bc6 e6 4. Nc3 g6 5. Qh3 d5 6. Qe3 black is winning

I stand corrected then, as I'm not about to argue with someone who has an IM title.

wasn't it you who tried to scholar mated him?

I thought scholar's mate was something like this "game" where white exploits the [f7] weakness.

Why did you have to go and necrobump this?
