Re: The brilliant chess move (19)
I found this one easy Walter. 
I supprised myself this time by even seeing the winning line before Deep Rybka 3. The poor fish on my Quad (Q6700) had it about even = (0.16)
[d]1k3q2/pp2n1pP/2PK4/2pR1b2/8/6Q1/8/8 w - - 0 1
1. Rxf5! Nxf5 2. Kd7+ Nxg3 3. c7 Ka8 4. c8(R) Qxc8 5. Kxc8 winning!
1. Rxf5! Nxf5 2. Kd7 Ka8 3. Qb8!! Qxb8 or Kxb8 4. c7 still wins!
Thanks I always enjoy your problems.

Re: The brilliant chess move (19)
By the way I went back and tested this with other engines and only Hiarcs 12.1 solved it quickly (Meaning it had the fastest solve time). Deep Fritz 11 was close second. I wonder why Deep Rybka had problems with this one. I think strong human players look at Rxf5 right away, given the position of whites far advanced pawns, I know I did right away.

There is hardly anything else to even look at!
I do not think that this was a special position with something to "find".
It is only a position to look at and see that everything is ok, and in this case it IS ok (for white).
