White's Game-Losing Mistakes

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

  • 4. cxd5, commits to exchanging Pawns, which Black obliges with 4...Nxd5. If White didn't want to lose his Nf3, which 5. e4 suggests, then this capture by the c-Pawn is a mistake, as it only serves to invite Black to play for the Knight exchange with his fourth move.

  • 5. e4, not expecting Black to follow through with the threat to trade Knights. However, with 5...Nxc3, that's precisely what happens. Okay, White does get two Pawns in the small center, but at a cost of a weakened Queenside, a weakness which Black begins to exploit (note Black's Queen: 10...Qa5+, 11...Qa3).

    5...Nxc3 gives White little choice but to play 6. bxc3. However, this capture removes a Pawn-guard from the b-file, creating a Hole at a3. Recall 11...Qa3; this wouldn't be possible if White's b-Pawn remained on b2, in light of White's dark-Bishop going absent from the c1-a3 diagonal. It all stems from 5. e4 and its sacrificial invitation to Black's Knight.

  • 7. Bc4, permits Black's c-Pawn to attack with 7...c5. White, then feels the need to defend this Pawn with the KN (8. Ne2), but this only serves to lose the original d-Pawn (8...cxd4) and further weaken the Queenside, taking another Pawn-step away with 9. cxd4.

    All of that subsequent action fails to get White's King Castled to safer territory. Note that the O-O Castled King wouldn't have lost the game in the manner it did. The whole dynamic of the game would have altered (though, the way White was playing, Black probably would still have the victory, sooner or later).

From 7...c5, White's moves all seem forced by Black's better coordinated attack(s). Black always seems in control all the way to victory, with only the 16th move of the game.
