Ne3#<br />1. ... Rxd4 2. Rc2#<br />1. ... Bb5 2. Qc3#<br />1. ... Ba7/Be5/Rc7/Rd6 2. N(x)e5#<br />1. ... Bc7/Rc5/Bc6 2. Q(x)c5#<br />1. ... Bd6/Rd5/Bd7 2. B(x)d5#<br />1. ... Rc6/Rd7/Ba4/Bf7/Bg6/Bh5 2. Q(x)a4#<br /><br />"Organ pipes" are always nice. :)PC Filhohttps://www.blogger.com/profile/16547063456626761789noreply@blogger.comtag:blogger.com,1999:blog-38193052.post-35005081257966291582018-02-09T20:14:20.133-02:002018-02-09T20:14:20.133-02:00White exploits the "organ pipes" layout ...White exploits the "organ pipes" layout of the black pieces with <b>1 Be4!</b> (waiting). Four pairs of Grimshaw defenses exist:<br /><b>1 ... Rc7/Bc7 2 Se5/Qc5</b><br /><b>1 ... Rc6/Bc6 2 Qa4/Qc5</b><br /><b>1 ... Rd7/Bd7 2 Qa4/Bd5</b><br /><b>1 ... Rd6/Bd6 2 Se5/Bd5</b><br />Also, there are numerous unguards, most of which repeat one of the above mates:<br /><b>1 ... Rc5 2 Qxc5</b><br /><b>1 ... Rd5 2 Bxd5</b><br /><b>1 ... Ba7/Be5 2 Se5</b><br /><b>1 ... B~(h5)/Ba4 2 Qa4</b><br /><b>1 ... f3 2 Se3</b><br />Finally, we have one selfblock:<br /><b>1 ... Bb5 2 Qc3</b><br /><br />This is the third problem featured on this blog which features the "organ pipes" layout, and, like the other two, it was a very nice one.jrh150482https://www.blogger.com/profile/10502831081969372299noreply@blogger.com
