Jul-26-09  vonKrolock: A position for the anthologies after <37.♔h2>


click for larger view

There's a forced mate in 12 with the actual move 37...e1=♘+!! Curious, that promoting to a heavy (<♕ or ♖> ) piece, black would find difficulties to avoid a perpetual with just the threats of white's ♕+♗, while if 37...e1=♗ the sequence would not be clear - and, finally, the very improbable coup 37...♗g1!!?? may be the <analysis room's dual> of the combination...

The game is very interesting, with a sustained attacking spirit animating the whole

Jul-26-09  crwynn: 37...Bg1+ does nothing, White can take the bishop and draw easily, or try 38.Kh1 and maybe win.
Jul-28-09  whiteshark: I'll post here a few game-related comments posted at the chesscafe:

Jul-23-09 whiteshark: I found the following position in a recent magazine.

It said it is Black's (Ian Nepomniachtchi) turn to move and to win and that it was a recent game. I've checked all of Nepo's wins back to 2006 but couldn't find it in the chessgames.com database. Does somebody or other knows the related game?

Jul-28-09  whiteshark: Jul-23-09 returnoftheking:

<white> Bg1! No idea what game it is.

Jul-23-09 whiteshark:

<returnoftheking> The game has been posted by <Chessdreamer> at the Nepo page. There you'll find the solution, too. :D

Jul-28-09  whiteshark: Jul-23-09 Wayne Power: <returnoftheking: Bg1! No idea what game it is>

.. Bg1+ as you say, but then, if Rxg1, Black promotes to a Knight with discovered check and has Qa6+, Qxg6+ and Nxf6+ to follow if White doesn't throw in the towel

Jul-23-09 returnoftheking: Bg1 was wrong..:(

Jul-23-09 Wayne Power <returnoftheking: Bg1 was wrong..:(> - no, glibness is wrong. Unless you have arthritis in your fingers, say why Bg1 is wrong.

Jul-28-09  whiteshark: Jul-24-09 Richard Taylor: In that diagram above 1 ...e1=N dis check looks like it leads to a forced mate. But I only just looked at it I haven't set the position up or anything.

Jul-24-09 Wayne Power: <Richard Taylor: In that diagram above 1 ...e1=N dis check looks like it leads to a forced mate> - yes and I can now see how ..Bg1+ is a red herring because it is met by by Rxg1 e1=N+, Kh1! Qa6+, Kg2 Nxf3 where Black still wins but less directly.

If 1 ... Bg1+ 2. Kxg1 e1=Q+ 3. Rxe1 Qxe1+ 4. Kg2 Qe2+ 5. Kh3 and White threatens mate on h7, so 5. ... Rxf3 6. Qh7+ Kf8 7. Qh8+ Ke7 8. Qe8+ (8. d6+ is another possibility) Kd6 9. Qe6+ Kc4 (!) 10. Qc6+ Kd4 11. Qb6+ Kc4 12. Qa6+ wins Black's queen is one dangerous var I can see. It might lead at least to a draw. Or there if 10. ... Kb4 11. Qb6+ Ka4 12. Be8# but if there 11. ... Qb5 12. Qd6+ Qc5 13. Qb8+ Qb5 14. Qd6+ Kc4 15. Qc6+ QxQ 16. dxc6 17. Be4 Rc8 18. Kg2 Kb3 19. Kf3 Kxb2 20. Kg4 a4 21. Kf5 a3 22. Bd5 a2 23. Bxa2 Kxa2 24. Kxe5 Rxc7 25. g4 Kb2 and black should win. That is just calculation practice! Actually after 10 ... Kb4 11. Qd6+ Kb3 12. Qa3+ probably= Or if 4. ... Qd2+ 5. Kh3 Qh6+ 6. Kg2 Qxg6 7. Qe6+ Qxe6 8. Rxf8+ Kxf8 9. dxe6 Ke7 11. Kf3 Kxe6 12. Ke4 and white might win.

I've probably made a lot of errors as I haven't set the position up, I am just analysing from the screen for now.

Good practice in any case!

But 1. ... e1=N+ 2. Kh3 Qg2+ 3. Kh4 (3. Kg4 Qxf3+ 4. Kh4 Ng2+ 5.Kh3 Nf4+ 6. Kh2 Qg2# or if 6.Kh4 Nxg6+ 7. Kh3 Nf4+ 8. Kh4 Qh5#) Nf3+ 4. Kg4 Nh2+ 5. Kh4 Rf4+ 6. Kh5 ( 6. gxf4 Nf3+ 7. Kh5 Qh2+ 8. Kg4 Qxf4+ 9. Kh3 Ng5# or 9. Kh5 Qh4#) Qf6+ 7. g4 Qh3#

Ther are other sub variations.

Jul-28-09  whiteshark: Jul-24-09 <Richard Taylor>:

I saw that Qh6+ idea. I think all the Americans and Poms are asleep!

==

I forgot to add if 7. Kg5 (instead of 7.g4 immed. above) then Rf5 ++ 8. Kh4 Qg4#

==

Yes 1 ...Bg1+ is an ingenious idea...

==

If 1 ... Bg1+ 2. Kxg1 e1=Q+ 3. Rxe1 Qxe1+ 4. Kg2 Qe2+ 5. Kh3 and White threatens mate on h7, so 5. ... Rxf3 6. Qh7+ Kf8 7. Qh8+ Ke7 8. Qe8+ (8. d6+ is another possibility) Kd6 9. Qe6+ Kc4 (!) 10. Qc6+ Kd4 11. Qb6+ Kc4 "12. Qa6+ wins Black's queen is one dangerous var I can see. It might lead at least to a draw. Or there if 10. ... Kb4 11. Qb6+ Ka4 12. Be8# but if there 11. ... Qb5 12. Qd6+ Qc5 13. Qb8+ Qb5 14. Qd6+ Kc4 15. Qc6+ QxQ 16. dxc6 17. Be4 Rc8 18. Kg2 Kb3 19. Kf3 Kxb2 20. Kg4 a4 21. Kf5 a3 22. Bd5 a2 23. Bxa2 Kxa2 24. Kxe5 Rxc7 25. g4 Kb2 and black should win"

Actually in this line I wanted to play
17. Bf5 (doesn't quite work), but I see now that that idea is good thus 17. c7! Rf8 18. Bf5!! - I would have seen it!! But it's a bit easier now with a pocket set! so 18. ... Kb3 19. c8=Q RxQ 20. BxQ Kxb2 21. Bd7

Of course the whole line is a bit fraught; but an interesting position for sure!

==

"If 1 ... Bg1+ 2. Kxg1 e1=Q+ 3. Rxe1 Qxe1+ 4. Kg2 Qe2+ 5. Kh3 and White threatens mate on h7, so 5. ... Rxf3 6. Qh7+ Kf8 7. Qh8+ Ke7 8. Qe8+ (8. d6+ is another possibility) Kd6 9. Qe6+ Kc4 (!)" That should be Kc5 (!)

==

I found the entire game - there is actually a site for this bloke - I was feeling a bit sorry for him with a name like that!

But he is one of those wonder kids GM at the age of 3 or something:

...

Jul-28-09  whiteshark: Jul-24-09 whiteshark:

After <37...Bg1+> White could also play <38.Kh1!> using the g1 as shield to cover backrank checks for the moment. And it's getting wild again: <38...Qh6+> (38...Rxf3 as candidate 2 with a kings hunt after 39.Qh7+ Kf8 40.Qh8+ Ke7 41.Qe8+ Kf6 42.Qf7+ Kg5 43.Qg7! winning at least the black rook) <39.Kxg1 Rxf3>

tbc...

Jul-24-09 Wayne Power:

<After tbc ... above (whiteshark)>

40 Qe8+ Rf8 41 Qe6+ Kg7!

- then if 42 Qxe5+ Kxg6 43Qe4+ Rf5 44g4 Qg5 should win. Else 43Qxe2 Rxg3+ 44Kf2 Qf4++

But 40Kg2 might hold on ...

  tpstar: <37 ... e1=N+!!> Brilliant. This game belongs in all Underpromotion Game Collections.

Note Black just sacrificed a Rook allowing 37. Bxg6 and his King was in mortal danger, until he crashed through first.
