Here is the output of Chest by Heiner Marxen for an interesting position that
was posted last Friday:
[D]8/8/8/2p5/R1P5/P5p1/P3K1p1/6k1 w - - acn 2550579538; acs 19996; bm Ra7; ce
32736; dm 16; pv Ra7 Kh1 Rh7+ Kg1 Kd2 Kf1 Rf7+ Kg1 a4 Kh1 Rh7+ Kg1 a5 Kf1 Rf7+
Kg1 a6 Kh1 Rh7+ Kg1 a7 Kf1 Rf7+ Kg1 a8=Q Kh2 Qh8+ Kg1 Qa1+ Kh2 Rh7#;

Uri wondered if there might be a shorter mate than 16 and the answer is no.
