I have it.

I have it.<br /><br />Any move of the e4-bishop will threaten 2 Be5, but most of these bishop moves fail:<br /><br /><i>1 Bd3?</i> (disables 2 Qd3) Re2!<br /><i>1 Bc2/Bb1?</i> (disables 2 Sc2) Be2!<br /><i>1 Bd5?</i> (blocks d-file) Bg7!<br /><i>1 Bb7?</i> (disables 2 Rxd7) Bg7!<br /><i>1 Bc6?</i> (disables 2 Sc6) d6!<br /><i>1 Bxf3?</i> (disables 2 Sxf3) Sg4!<br /><i>1 Bxf5?</i> (also threatens Re4, but disables 2 Sxf5) Qe7!<br /><br />This leaves <b>1 Ba8!</b>. Now White has responses for each defense that defeats a try (the first three defenses listed are self-interferences):<br /><b>1 ... Re2 2 Qd3</b><br /><b>1 ... Be2 2 Sc2</b><br />(These two defenses are a Grimshaw pair!)<br /><b>1 ... Bg7 2 Rxd7</b><br /><b>1 ... d6 2 Sc6</b><br /><b>1 ... Sg4 2 Sxf3</b><br /><b>1 ... Qe7 2 Sxf5</b><br /><br />There are other defenses, but White has responses for these too:<br /><b>1 ... Qg7 2 Sxf5</b><br /><b>1 ... Qh8 2 Sxf5/Rxd7</b><br /><br />I don't like that this problem contains a dual, but it's in the by-play, so whatever.<br /><br />P.S.: I find it hard to believe that <i>any</i> two-mover can get five stars in difficulty, unless retroactive analysis is somehow involved.jrh150482https://www.blogger.com/profile/10502831081969372299noreply@blogger.comtag:blogger.com,1999:blog-38193052.post-19630059435782517312018-05-18T13:04:02.496-03:002018-05-18T13:04:02.496-03:00Level: very hard! ⭐⭐⭐⭐⭐Level: very hard! ⭐⭐⭐⭐⭐Unknownhttps://www.blogger.com/profile/06377619908080953145noreply@blogger.com
