Hallo Gerhard!

Es dürfte sich um ein Matt in mehr als 37 handeln, genau ausrechnen kann ich's leider noch nicht ganz.

8/3pp3/8/4P3/6KB/7P/2P3k1/3n4 w - - 0 1

1. Be1 Ne3+ 2. Kf4 Nxc2 3. h4 Nxe1 4. h5 Nd3+ 5. Kf5 e6+ 6. Kf6 Nf2 7. Kg5 Nh3+
8. Kh4 Nf4 9. h6 Ng6+ 10. Kg5 Nxe5

Diese ersten 10 Züge sind aber zwar wohl die HV, danach wär's ein M37, weil der danach entstehende 6Steiner eines in 27 ist.
Mit z.B. Zappa Mex.2 mit mate extensions on kann man aber vom entsprechenden 6Steiner in absehbarer Zeit nur bis zum 3. Zug das Matt zurück mitnehmen, weiter aber nicht so bald:

weil offenbar 3... Sd4 statt 3... Sxe1 den Überlebenskampf von Schwarz noch etwas verlängert:

Sorry, das mit 3... Sd4 war doch eine kürzere Sackgasse als ich dachte:

Das ist also nicht die längste Verteidigung, bleibt nur noch gegenüber der HV 2... Sd5 statt 2... Sxc2 auszurechnen, ich bin allerdings eigentlich jetzt wieder recht zuversichtlich, dass es sich in 37 Zügen längstens doch ausgehen sollte.
