H. Reddmann, Lüneburger Landeszeitung 2024
 (= 9+8 )
You can now add a bPe4 to add another ambush generated by the key
(I left it "as is" as the key gets even worse), totalling 5 ambushed
pieces and 6 ambush mates.
Record? Morse doesn't even list this theme. Neither "Hinterstellung"
in the Albrecht gives something.
BTW, wPb6 instead of Qa8 Ba7 Sb5 suffices :-)

Not ambush, but gate opening records:

You can change this position a little and get the key with wQ ambushes:
 (= 12+10 )
#2
1.Qc4
The matrix is almost identical to the problem of the 1st post.

I agree, this totally anticipates me.

Another Albrecht digup for line opening "TaskLinienÖSW"
(as gate opening; no ambush!):
