A Paradox of Chess Logic

@SOSOonagain @Arisktotle

Yes, here's Spassky's commentary from Nadareishvili's 'Chess Study through the Eyes of Grandmasters'

"The beauty of the study lies in the paradoxical logic. First, let's state this,

1) the promotion loses to 1...Bf5+

2) the roundabout way via a7 doesn't help as, with Black's King on c8, the move Kb6-a7 meets with b7-b5

3) 1.Ke6 doesn't work due to 1...Ke4 1...Kf4 or 1...Kg4

Remains, 1.Kc8! breaking Black's fortress,

1...b5 2.Kd7!! threatening, in the first place, 3.Kc6

3.Kd6 Bf5

4.Ke5! gaining a tempo and getting in the b-pawn's box. If now 4...Bc8 then 5.Kd4 Ba6 6.c8Q Bxc8 7.Kc4. Any other move by the Bishop doesn't change anything

4...Bf5

5.Kd4 with a draw

"A beautiful study!"

Thanks for sharing, it’s a beautiful painting, albeit the ruins within
