Any knight move is defeated by 1 ... c4+!, so the key is a rook move, namely <b>1 Re3!</b>, turning the half-battery into a full battery, setting up another on the third rank, and threatening Nd~. Many defenses force one of these seven knight moves: <b>1 ... Kb4 2 Nxc2; 1 ... Qh1+ 2 Nf3; 1 ... Qh5+ 2 Nf5; 1 ... Qg8+ 2 Ne6; 1 ... Qa8+ 2 Nc6; 1 ... c4+/Qd8/Qf8/Qg7/Qh6/Qh4 2 Nb5</b>; and <b>1 ... Rb~ 2 Ndb3</b>. The correction <b>1 ... Rb4+</b> is a self-block that allows <b>2 Bc4</b>, and <b>1 ... cxd4+</b>, in much the same way as the aforementioned pawn defense, opens the a3-c5 line and allows <b>1 ... Bb5</b>.<br /><br />I really liked this problem on account of all the battery plays and cross-checks involved. Also, I would like to add that I did not look at the previous posts to come up with the solution.<br />jrh150482https://www.blogger.com/profile/10502831081969372299noreply@blogger.comtag:blogger.com,1999:blog-38193052.post-58709006440581045712015-10-18T11:07:09.974-02:002015-10-18T11:07:09.974-02:00O peão não pode ir para a casa e1, pois não é um m...O peão não pode ir para a casa e1, pois não é um movimento permitido.PC Filhohttps://www.blogger.com/profile/16547063456626761789noreply@blogger.comtag:blogger.com,1999:blog-38193052.post-43387010189671957972015-10-18T02:36:50.161-02:002015-10-18T02:36:50.161-02:00 pião E-2 para E-1, depois,cavalo D-4 para E-2 e X... pião E-2 para E-1, depois,cavalo D-4 para E-2 e XEQUE-MATE.Anonymoushttps://www.blogger.com/profile/17397185530057388637noreply@blogger.com
