Missing the Pawn Centre

Massive congratulations to my opponent in outplaying me. I learnt much from this defeat, particularly for how Black orchestrated the ... c5 break to converting an Queen ending a pawn up with minimal risk.

More so, the research into the opening lead me to the game Harikrishna - Shabalov, 2004 1-0 where I can see the difference between 12. dxe5 and 12. Ne2 is all due to setting up f4 and building a big pawn centre
