The Hippopotamus Defence is just what a club player needs. It’s a straightforward and clear-cut chess opening that avoids the ever growing body of mainline theory. It’s universal: Black can use the Hippo against virtually all of White’s choices (1.e4, 1.d4, 1.c4, 1.f4, the Colle, London, Trompowsky, Réti and others). It’s not very well known and will surprise many opponents.
