White's Game-Losing Mistakes

White's game-losing mistakes appear to be ...

  • 3. exd5, I just wonder whether this was too early to make a capture, due to lack of support for White's e-Pawn, and that 3. e5, creating an Advanced Chain, would have been better for White's prospects, long-term?

    As it happened, 3. exd5 merely setup Black's Queen on d5 for her eventual sacrifice, which helped pull White's QN out of position (6. Nxd5), exposing White's exposed, centralized King. Black's Queen is also shielded by White's very-own d4-Pawn.

  • 4. Nf3, enables Black's Pin with 4...Bg4, which effectively removes the support of the d4-Pawn, which the very act of playing 4. Nf3 intended.

  • 5. Nc3, doesn't help Qd1 & Nf3 protect the d4-Pawn, which seems to be what's needed, here.

    Playing 5. Be3 would have, while also developing White's dark-Bishop; it would also free White's Queen to break the current Pin from Bg4.

    White, unwittingly, permits 5...Bxf3, leaving Qd1 the sole protector of the d4-Pawn.

  • 7. Nxc7+, having captured Black's Queen, White possibly gets overexcited at the prospect of playing an Absolute Fork, to capture Black's Ra8.

    This is a mistake, given White's own lack of development, while Black has a Knight developed to a good square and a light-Bishop active and free to do damage to White's Queenside Pawns, further exposing White's un-Castled King.

  • 9. Bf4, White possibly hopes to double-up with his Na8 to land a few checks against Black's similarly exposed, centralized King.

    But, White fails to spot the vulnerability of his d4-Pawn by playing Bf4, perhaps with his attention on Black's e-Pawn with d4 as back-up for White's dark-Bishop?

    Black's 9...Nxd4 highlights, then compounds White's error, to the latter's further disadvantage.

    Black appears in control with his remaining, game-winning moves.
