The Bongcloud arises after 1.e4 e5 2.Ke2 (ECO C20) - White moves the king on move two. This is the famous troll opening: it breaks every principle, forfeits castling, blocks the pieces and exposes the king.
Objectively it is one of the worst moves available, and there is no serious fight for an advantage here. But the opening became an internet legend and even appeared in top-level games: in 2021 Magnus Carlsen and Hikaru Nakamura played the Bongcloud for a laugh in an online tournament.
This page is simply a curiosity to look at: set the position up and see why the king move is so bad. Playing it seriously is, of course, not recommended.
Drag a piece onto the board, or click a piece and then click the squares. The cross beside the pieces sweeps every piece of that colour off the board, and a single piece can be dragged off the edge.
The pieces will be arranged into the chosen pattern.
