Many different cooks found by the program I’m working on. For example:

1.Sh3=b Sf4 2.c3=b Sxe2 3.Bxe2 f6=w 4.O-O cxd2 5.Qxd2=b Qxe2 6.fxe7 Qg4 7.f3=b Qxg2#
1.c3=b f6=w 2.d3=b dxe2 3.fxe7 exf1=S 4.Qg4 Sxh2 5.f3=b Sxg4 6.Kf1 cxb2 7.Rh2=b bxc1=R#
1.f3=b fxe2 2.c3=b exf1=S 3.Qg4 cxd2+ 4.Kd1 dxc1=S 5.Kxc1 f5 6.Sf3=b fxg4 7.Rg1=b Se3#

Can you test the correctness of this type of PG?

Yes, but only for fairy conditions that I have programmed. I programmed Volage specially to be able to test this problem. I’ll be releasing my program soon so that everyone can test problems. I don’t think I have any choice, if I’m the only one with this tool then my personal mailbox will be filled with private requests from composers to test their originals. 🙂

I suppose the Orthodox rules should be without problems. Could you test me a short SPG (dia8.5)?

I prefer if you wait for my program. With fewer distractions I can finish it sooner. I think I can get the first version out sometime in October.

I thought Popeye checks it.

Is it really “big unmasking” in 1237.1?
Or is it simply a diagram error?

Yes, indeed, 15 units are visible, because it is this position which I verified with Jacobi.
