Thanks for such a detailed explanation of the solution.<br /><br />About your PS question: today I will probably publish a not-so-long moremover (mate in 19). And then we will return to our good old 2-, 3- and 4-movers, unless I unexpectedly find something amazing in my study sessions. :)PC Filhohttps://www.blogger.com/profile/16547063456626761789noreply@blogger.comtag:blogger.com,1999:blog-38193052.post-62759210921046451382019-04-02T06:22:43.728-03:002019-04-02T06:22:43.728-03:00First White plays 1 Bf4! threatening immediate mat...First White plays <b>1 Bf4!</b> threatening immediate mate at e3. The only defense is <b>1 ... Kc5</b>. After <b>2 Be3+ Kb4</b>, <b>3 Bc1!</b> threatens mate at a3. Again, the only defense is moving the king with <b>4 ... Kd4</b>. White then plays a tempo move that forces one of the h-pawns forward: <b>5 Bd6!</b> (waiting) <b>h4</b> (other possible moves get Black mated more quickly). This sequence is repeated several times (I will not call any further attention to the mate threats for the sake of brevity):<br /><br /><b>6 Bf4 Kc5 7 Be3+ Kb4 8 Bc1 Kc5 9 Ba3+ Kd4 10 Bd6! h3 15 ... h5 20 ... h4 25 ... h6 30 ... h5 35 ... h2 36 Bxh2 Kc5 37 Bd6+ Kd4 38 Bf4 Kc5 39 Be3+ Kb4 40 Bc1 Kc5 41 Ba3+ Kd4 42 Bd6! h3 47 ... h4 52 ... h2 53 Bxh2 Kc5 54 Bd6+ Kd4 55 Bf4 Kc5 56 Be3+ Kb4 57 Bc1 Kc5 58 Ba3+ Kd4 59 Bd6! h3 64 ... h2 65 Bxh2 Kc5 66 Bd6+ Kd4 67 Bf4 Kc5 68 Be3+ Kb4 69 Bc1 Kc5 70 Ba3+ Kd4 71 Bd6!</b> (waiting)<br /><br />Black is now in zugzwang:<br /><br />71 ...
