The last move by Black leading to this position must have been absolutely ridiculous. That's why I don't like this kind of studies. No offence against Mr. Afek intended - just the point of view of a practical player.

The final position does look a little bit out there, but you must agree, it is B-E-A-utiful!! Thanks Afek!

What is wrong with Ke7, g6-g7-g8Q and Qh7xh2 checkmate? This looks too easy.

What am i missing? Because dy sais it is beautifull it is probably not this line:

1. Rb1 - b2 2. Kc7 - d6 3. g6 - d5 4. g7 - d4 5. g8/q - d3 6. Qd5 - d2 7. Rxb2. Seems mate on g2 is follow soon.

@Stefan. The only alternative for black is draw by repetition. The example illustrates why the game is drawn if the the black bishop captures the white one.

Too easy - all forced winning continuation

1.Rb1 b2 2.Kd5! d6 3.Kc6! d5 4.g6 d4 5.g7 d3 6.g8 (B)! d2

7.Bb3 d1 8.Bd1 Bd4 (wherever) 9.Bg4+ Bg1 (9...g1 10.Bf3#) 10.Bd1 Bf2 11.Bf3+ Bg1
12.Rb2 +-

1-0

What happens after 8....Be3 9.Bg4+ Bc1?

What happens is ... black wins! That's why the solution starts with Rd1 instead of Rb1. In that way black is obliged to sacrifice his b-pawn before his d-pawn. Which eliminates the black rescue operation with b2 and Bg1-e3-c1

Jadoube: on Qxh2 Kxh2 follows! :)

Sergio's picture

Is my solution wrong cause 7 ... Be3? But then white plays 8. Qe4 , B somewhere on the g2 - a6 diagonal is followed by Rxd2.

What am i missing that i read nice solutions with underpromotion, but i got the feeling it isn't needed.

@ Sergio

In your variation black can play 2...d5

I nominate RamnathBhuvanesh's comment as the most epic one to be found on this site in the entire year.
Apart from the fact that it's totally unbelievable someone finds the solution in any way 'easy' (without using an engine), he manages to call the moves 'forced' when they're not forced at all, then misses the entire point of the study, giving an incorrect line without noticing what's wrong with it. But most importantly, he seems to miss out on the rare beauty of the study - regardless of whether his solution was correct or not.
You know, this is not a contest where words like 'easy' at all apply - it's a place where you can enjoy the beauty of chess and Mr. Afek is doing a great job displaying just that.

@cak thank you i knew is missed something obvious, otherwise the study isn't that beautifull.

Ramnath's picture

1.Rd1 b2 2. Kd5 d6 3.Kc6 d5 4.g6 d4 5.g7 d3 6.g8(B) d2 7.Bb3 b1 8.Rb1 d1 9.Bd1 +- and this wins since there's no Be3 and Bc1 as mentioned above!

my idea was absolutely correct- but as u said, i missed that trick- and this is my improvisation

Ivo's picture

1.Rd1! b2 2. Kd5! d6 3. Kc6! d5 4. g6! d4 5. g7! d3 6. g8B! d2 7. Bb3! b1Q 8. Rxb1! d1Q 9. Bxd1 Lf2 10. Bxg4check Bg1 11. Bd1 Bf2 12. Bf3check Bf1 13. Rb2 Bf2 14. Rxf2 Kg1 etc.

Sergio's picture

@Ramnath missing that trick would make the difference to losing or winning your match. I don't think you find it easy anymore. Otherwise you found the trick.

Is Kc6 better then e6? Or doesn't it mather as long as you have it on a white field?

Alexander's picture

I think Ivo has given the full solution. With 1. Rd1 Black does not have the Bc1 resource any more, as in the 1. Rb1 variation.

@Sergio: Kc6 is the only solution since Ke6 blocks the Bishop's path to b3.

Sergio's picture

@Alexander. thank you. Next time i look more then 15 minutes before asking or posting anything here. Already mentioned some variations that fail on such easy things. Not gonna emberras myself further.
