As i am not using a computer of course and as my first quick thought (at night my brain gets lazy but i am very tempted to write something about this position ) i see the following:
White is almost in checkmate, the knight on f2 it is keeping alive the white king but not for much time, black bishop can be exchanged for this knight and goodbye white king
I believe the move is 1.Qxc7+ the only quick attack for white if 1..KxQ then 2.Ne6+ then the black King is in trouble
Only 2 moves ahead at overnight regards
Ricardo

Greetings all!
Like Ricardo, my initial impression was that 1.) Qxc7+ followed by 2.) Ne6+ would lead to mate, however, after looking at the position a bit longer, I came to realize that Bc8 foils the mating net.
As of this writing I am unable to find a mate, though I think I’ve found a perpetual after sacrificing the queen (necessary in all lines I believe) and white’s remaining knight.
1.) Nc6+ Bxc6
2.) Rxd8 Nxd8
3.) Rxd8 Kb7
4.) Qxc6+ Kxc6
5.) Bf3+ Kc5
6.) Nd3+ Nxd3
7.) Rd5+ Kc6
8.) Rd6+ Kc5 (repeat 3 times)
Will ponder more tonight regards...

Last attempt
It's late here and I'm not sure want went wrong in my earlier calculations:(
1.Nc6 Bxc6
2.Rxd8+ Nxd8 (I missed this knight earlier wtf?)
3.Rxd8+ Kb7
4.Qxc6+ Kxc6+ (I mistakenly called this the b-file earlier)
5.Bf3+ Kc5 (5...Nd5 makes it easier for white)
6.Ne6+ Nxe6
7.b4 Kc4
8.Be2#
Just visualizations once again. Hope it's right this time ...
Scrambled brain regards,

It looks like you’re on the right track, though you can’t play 6.) Ne6+ since you sacrificed the d4 knight with 1.) Nc6+.

Re: Last attempt
Damn it. I'm sure I could get it if I played a few moves over the board but that would be cheating. I just need to kick that f4 knight away ....Cyberchess wrote:Greetings tt:trontreez wrote:It's late here and I'm not sure want went wrong in my earlier calculations:(

It's starting to get at me too. I'm still half asleep here so maybe I'll give it another try in few hours.kgvetter wrote:Hi,
as I was unpatient I used a physical board (not an engine) to find the solution, nice problem!
Naturally I won't share my findings, but I compliment anybody who can find the solution by sheer visualisation!

I had given up after finding what I believed to be a perpetual.
Try, Try Again Regards,
