<p class="note">Main article: Leghorn Special</p>
<p>The Leghorn Special (白色レグホン・スペシャル <i>hakushoku reguhon supesharu</i> or, most commonly, the abbreviation レグスペ <i>regusupe</i>) is an opening in which you build up a <a href="/facts/Bear-in-the-hole_castle/SooYevwq">Bear-in-the-hole castle</a> while you're simultaneously defending against an opponent's Bear-in-the-hole. It is a Bear-in-the-hole <a href="/facts/Bishop_Exchange_Fourth_File_Rook/FBAkxKIU">Bishop Exchange Fourth File Rook</a> variation and is also famous as an opening to discourage Black from building of a Bear-in-the-hole. The name is said to have originated in the resemblance of this opening to the behavior of a white <a href="/facts/Leghorn_chicken/cghrkbmc">leghorn chicken</a> that keeps attacking when surrounded by Bear-in-the-hole.
</p><p>The leghorn special consists mainly in castling the king in Bear-in-the-hole once the bishops have been exchanged in Fourth File Rook. It requires that the opponent is playing Static Rook, and that you're playing White. Following Black's K-68, White would go for the bishop exchange (Bx88), which leads to Black's Sx88, hence reducing the escape routes of Black's king and interfering with Black's castle formation. So, the Leghorn Special prevents (or at least slows down) Black's Bear-in-the-hole, while White can devote to building its own Bear-in-the-hole without problem.
