Up to here a standard opening, but white moves knight for the second time. Considered a no-no until other pieces have been developed.
4... Qd8e7
Black should have captured the knight with the queen's pawn. As a result, black is now already a pawn down.
5. Ne5g6
On the face of it, a stupid move by white who could have got its knight out of danger. Maybe counting on black doing the same bad move again, maybe just carelessness.
5... fxg6
Black did the right thing this time, although it may have messed up black's castling.
6. O-O Bc8e6 7. Nb1c3
stupid move by white, who should have protected or retreated that white-square bishop currently under threat.
7... Be6xc4
Black did the right thing and is now threatening white's rook as well.
8. Nc3d5
Another stupid move by white, considering that endangered rook.
8... Nf6xd5
White made the wrong choice (a 3-point knight, rather than a 6-point rook).
9. exd5 Bc4xd5 10. d3
Wonder why white didn't do Re1 and skewer black's queen and king? Another stupid move by white.
10... Nb8c6 11. d4
White's just used 2 moves to take the D pawn 2 steps, could have been done in 1. Not productive, and still ignoring that lovely skewer.
