Centre Game

This opening was mostly abandoned by 1900 because no advantage could be demonstrated for White. It was revived in the 1980's and Grandmasters contributed to the theory by re-evaluating lines thought to favor Black. White succeeds in eliminating Black's e-pawn and opening the d-file, but at the cost of moving the queen early and allowing Black to develop with tempo with 3...Nc6. In White's favor, after 4.Qe3, the most commonly played retreat, the position of the white queen hinders Black's ability to play ...d5. The back rank is cleared of pieces quickly which facilitates queenside castling and may allow White to quickly develop an attack. From e3, the white queen may later move to g3 where she will pressure Black's g7-square. Wikipedia
