Non-thematic attempts: 
1. Tf4? (2. De6+ Kxf4 3. Le5+ Ke3 4. Lh2+/Lg3+ Kd4
5. Lg1+/Lf2+ Le3#) Sc7!! Nothing else!
1. Txc5? (2. De6+ 3. Le5+ 4. Lh2+/Lg3+ usw.) Ld7!!
Nothing else, again! See below
1. Dd6? (2. Dd2+ Lxd2#) Lxb2+! 2. Dd1... Over
However, Setplay:
1. -  cxb2? 2. Dd6! b1S, dresdnerisch (instead of - Lxb2+)
3. Txc3+ Sxc3 4. Dd2+; 2. - b1L 3. Te4+/Sf5+ Lxe4/Lxf5
4. Dd2+.
                            
Thematic:
1. Dxc3?? = wrong mate!
Without Queen, however, White could play 1. Lxc3 ~
2. Ld2+ Lxd2#.

How to get rid off Queen with - necessary! - tempo?

1. Sf7! (2. Dd4+ cxd4 3. Lxd4+ Kf4 4. Sg6+ Kg3
5. Le5+ Lf4#)
1. - Lxf7 
2. De6+! Lxe6
Temptation: 3. Sf5+? Lxf5 4. Lxc3? (5. Ld2+) Lb1!!
3. Lxc3! (4. Ld2+) Lxc4! (4. - Kd4!)
AND:
4. Sf5+ Kf4
5. e3+! Lxe3#
6. Ke2?? 

1. - cxb2 2. Dd6! etc., see setplay

[1. Txc5? Sc7? 2. Sf5+ 3. Se6+ 4. Tc4+/Dd4+
5. e3+; 1. - Sxc5? 2. Sf5+ 3. Dd4+ Se4 4. De3+ = shortest]
