This is probably your first glitch, Nd4 will now hand black the inititive. The simple option of Be3 will prevent this and aim to give you a solid bishop swap.

Just like i said...

Good to see your confronting your mistakes head on and learning from them.

Nice from Ethan, sets up a future d5 and threatens a first round knockout with Qf6 (without c6, Nd5 is too big a counter punch against Qf6.)

I wonder why no one has castled yet?

Dean repels the threat in the most boring manner he can... Be3 would have got the job done whilst dragging another piece into the party.

There's no way you'll be castling kingside in this position, the one good thing is he won't really be able to either, the open g file could be too much of a menace...

Surprisingly bright thinking dean, the pawn could also be annoying to defend later on, like in queens or kings gambit games.
