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. On top of all that, the Hippo is seriously underestimated: with its characteristic double fianchetto it may look quiet, but inside there lurks a very dangerous animal. FIDE Master Alessio de Santis is one of the world’s greatest experts on the Hippo and has written a practical, well-structured and accessible manual.
