Some basics: 
1. Sa~? (2. Sf6+ Txa8 3. Tf2+ Lxf2#) La4!
1. Lc6?/1. Ld5? (2. Sg3+! Kg4 3. Ld7+,Le6+ Kf3 4. Tf2+)
1. - Dg7(!) 2. Sf6, wrong mate; Db7??/1. - Df6!

1. Tc5! (2. Tf2+ Kg4 3. h3+! Kxh3 4. Th2+ Kg4 5. Tg5+! Kf3
6. Th3+! Lg3#) De5? 2. Sf6+; 1. - Df6? 2. Tf5+! Dxf5 3. Sf6+
1. - bxc5
2. Lb7? (3. Sg3+ 4. Lc8+) Dh8(!) 3. Sf6, wrong mate; Dxa8?? 
2. Sb8?/Sxb4?/Sxc5? La4!
2. Sc7!! La4 Txa8? 3. Sd2+! Lxd2#
3. Sxb5 (4. Sd4+ Dxd4/cxd4 5. Sf6+ D~/Lc6 6. Tf2+)
3. - Txc2 (4. - Dxd4! flight, battery-annihilation)
Finale:
4. Sg5+! Kxe3
5. Sf3+! Kd3
6. Sxe1+! Txe1?? Dxe1#!

Thematic try:
1. Sc7? La4 2. Sxb5 thr. primarily (3. Sd4+) Db1?,Tc3?,c3?
3. Lc6,Ld5! ~ 4. Sg3+ etc. However: 2. - Da2!! selective flight 3. Lc6?,Ld5? Txc2!, quickest. Therefore 1. Tc5! bxc5(!),
so that 3. - Da2 is becoming ineffective...

Demolition of black double-battery under specifically electrifying circumstances - from introductory full-length threat through stimulating temptations until to "grotesque" final point: direct mate by black queen capturing white battery's front piece at e1...

Another complex example out of the mysterious universe between Anziehung / attraction or initiation of interference and Abstoßung / flight or avoidance of interference.
