Double Push King's Pawn Opening, 1.h4[edit]

Red pushes the pawn two squares instead of one. This is slightly weakening the king's position, since the pawn can no longer block checks supported by g2 and i2 and on h4 the pawn is undefended.

Blue's responses[edit]

Blue can reply in the same way as against 1.h3.
