This post is all about amusingly named chess openings,nearly all of which are named after animals.The opening which I find to be the funniest is the so called monkey's bum.There are many amusingly named chess openings,and I have included most of them below but I have left a few out.Amongst the openings I list below is the amusingly named Pterodactyl defence and then there is the Hippopotamus defence,which is beloved by various British players including this British player.
