Aronian – Dubov after 47…Kf6. This position is a technical win for white. However, white MUST understand the winning motif. Pushing the g pawn too early would result in a draw.
For example, in this similar position, it would be a draw if white plays either g3 or g4. Therefore, white MUST push the pawn ONLY at the right time.
On the other hand, in this position, g4 is the right winning move. Do you understand why?
