Black to move. Can Black win this position?
c3 looks winning….
Rxb2!
(has to be something
spectacular)
..rxb2 looks interesting, dont know how to stop one of two c pawns from queening.
Maybe ..c3 is also a forced win ?

1. … Rxb2 wins for black. 2. Nxb2 c3 3. Nd3 c4+
Kamal, that’s only half the story 🙂
1…Rxb2 2. Nxb2 c3 3. Rxb6 (not Nd3) 🙂 Now what? 🙂
Best wishes,

It could be 3. Rxb6 c4! Isn’t it impossible to stop the pawn promoting then ?
Susan Polgar, did not see 3. Rxb6 🙂
But, Misa seems to be right 3. … c4 should do the trick?
1. … Rxb2!
2. Nxb2 c3
3. Rxb6! …
and 3. …c4 looks very fine but seemingly it is not the last move to be found by black 🙂
3. …c4!
4. Rb4! …
and the only winning move is
4. … a5!!
(lot’s of exclamation marks …)
could you explain more?
– Vinay
1… Rxb2
2. Nxb2 c3
3. Rxb6! c4!
4. Rb4! a5!!
(4… cxb2? 5. Rxb2 +-) (4… c2? 5.
Rxc4 +-)
5. Rb5 c2! -+ and the pawn passes
(5… cxb2? 6. Rxb2 +-)
(5… a4? 6. Rb4 +-)
hopefully enough explanation – sincerly, anonym
Hello everybody! This position is very famous and it’s incredible!
Ortueta-Sanz.
What a beautiful combination!
And incredible, because it is very probably a hoax!
