One of my online chess games. Some annotations below . . .
2. g3 This opening move doesn’t have a name as far as I know.
4. Bxe4? There’s no way I can see for Black to save the pawn after 4. Nc3 so why put the bishop out there as a target?
6. b3? 6. h3 would prevent Black’s follow-up move.
7. Ng2? 7. Bxc6+ knocks out a valuable Black piece.
8. Bf1?? White’s game is probably lost already so instead of prolonging with something like 8. Nc3, why not just commit suicide?
