c4! Kxc4 (dxc4 e3#)
Rc1+ Kb3 (Kd4 e3#)
Rc3+ Kb2
Ra2+ Kb1
Rc1#
How about Nxc6+ Rxc6
R-a4+ R-c4
e2#
GTK
The right move is indeed 1.Nxc6+
Black wins after 1.c4? Rxb4! 2.e3+ Kxc4 3 Rc1+ Kb3 4.Raa1 Bf6
after 1. Nxc6+, another interesting variation is:
1… Kc4 2.Ra4+ Kb5 3.Nxa7+ Kxa4 4.Ra1#
NxR, RxR, Ra4+ Rc4 e2#
Relatively easy one, only took like 15 seconds.
Easy! We need a chess training program to get our 8 club players to around 2300 for starts. No need to get titles, only deserved rating. How can we do it?
Mayadi , your tactic is beautiful. However I think a shorter but simpler solution-line goes like this:
1. Nxc6 Kc4
2. Rh1-a1
with the threat 3. Ra1-a4 ++
2…… Rxc6
3. Ra1-a4++
I saw Mayadi’s line, but instead of 3. Nxb7+, I saw Nd4+, with the same result.

Why not to post also the FEN in the Puzzles and Tatics problems?
1.Nxc6+
if 1..Rc(b)xc6 then 2.Ra4+ (2..Rc4 3.c(e)3#)
if 1..Kc4 then 2.Rha1 (threatening R1a4+) wins even more material and maintans the heavy attack

mayadi:
You are right. Your solution is better because I overlooked (in the 1..Kc4 line) the 2.Ra4+ Kb5 3.Nxa7+ Kxa4 4.Ra1# continuation (as you wrote)

Good idea, but… as for me, I might simply copy&paste it into Fritz if I can’t find the solution within a certain amount of time… that’s not so improving.
Lets get to the 1.c4 line
1.c4! Rxb4!?
(1…..Kxc4(1…..dxc4 2.e3#)2.Rc1+
Kb3 3.Rc3+ Kb2 4.Ra2+ Kb1 5.Rc1#)
(1…..Bb7 2.Rc1 intending 3.e3#)
(1…..Rxa6 2.Rc1 Rxa5 3.cxd5 intending 4.e3+)
2.e3+ Kxc4
3.Rc1+ Kb3
4.Rb1+ Kc4
5.Rxb4#
1.c4? Rxa6
2.Rc1 Rxa5
3.cxd5 Ra2+!
4.Nxa2 (what else?)
4….Kxd5 Black win
