About the Kádas Opening
White starts with 1.h4, a very offbeat move that does little for the centre. It is mostly a surprise weapon.
The idea is to use the h-rook via h3 or to push h5 later.
Black should just take the centre with ...d5 and ...e5.
White's kingside gets weaker, so castling short is less safe.
