Antibattery mates 1

Our 6th TT CCM is dedicated to antibattery mates. By chance issue 130 of feenschach was recently delivered to me and it contains long article by GM Petko Petkov that describes his method of creating new problems from old schemes, cooked or not sufficiently constructed problems. As an example he shows many varying problems originating in simple antibattery scheme. So you can take these problems as examples too...

1.Sd3 Rxd3(Sg8) 2.Qxb3(Gb8) Nd6#

Excellent Circe strategy. First black move opens line for 2nd black move and provides piece that after capture on 1st white move in fact unpins white piece before activation of 8th rank, 2nd black move sets G to b8 and then antibattery mate follows.

h#2 (4+12)
1+0 nightrider, 1+1 grasshopper
