Chess opening Stonewall Attack lecture inc. tactics, themes, lesson, etc.

The Stonewall Attack is queen’s Pawn Opening, characterised by White playing d4, intending e3, c3, f4 with Bd3 and Nbd2. As a system opening, the moves are often not in strict order. If Black fails to react actively, White may develop a lethal attack on the Black King, with themes such as: Ng1-f3-e5, Rf1-f3-h3, and Bxh7+ as a precursor to Qd1-h5 — where Queen and Rook combine on the h-file. The Stonewall Attack can arise with transitions from the Colle system and Bird’s openings, and also shares some similarities — in terms of themes and patterns — with the Dutch Stonewall Defence.
