|Apr-13-13|| ||morfishine: The only candidate I considered was <30.Re8> but thought it failed to 30...Qh2+ 31.Kf1 Rxe8|
I then tried to 'set up' Re8, but grew tired and so checked the solution and lo and behold, 30.Re8 was the move all along...Of course, all I had to do was 'see' one move ahead [ie: 32.a6] :(
|Apr-13-13|| ||agb2002: White has a bishop and a knight for the bishop pair.|
Black is probably considering 30... d4 31.Bxb7+ (there was the threat 31... Qh1+ 32.Bxh1 Rxh1#) 31... Rxb7 32.Qxh6 (32.Qxc5 Qh1#) 32... Rxh6 and White has problems.
The rook on h8 protects the black queen so Black's back rank is weak and White can threaten mate at once with 30.Re8:
A) 30... Qxb6 31.axb6+ Ba6 32 Rxa6+ Kb7 33.Rxh8 Kxa6 34.Rxb8 Kxb5 35.b7 Kb6 36.Rc8 Kxb7 (36... Rxb7 37.Bxd5 and the pawn on c4 is lost) 37.Rxc5 Kb6 38.Rxd5 + - [B+3P].
B) 30... Bc6 31.Rxh8 Qxh8 32.Qxc6+ Rb7 33.a6 and mate soon.
C) 30... Qh2+ 31.Kf1 Qh1+ 32.Bxh1 Rxh1+ 33.Ke2 Rxa1 34.Qa7#.
D) 30... Rd8 31.Rxd8 + -.
E) 30... Bc8 31.Rxc8 Qxb6 32.axb6+ Kb7 33.Rxh8, etc.
F) 30... Ba6 31.Rxh8, etc.
G) 30... Qh2+ 31.Kf1 Qxg2+ 32.Kxg2 d4+ 33.f3, etc.
|Apr-13-13|| ||agb2002: 33.Qxb7+ leads to a much easier endgame than 33.f3 Rxe8 34.a6 Re2+ 35.Kf1 Bxf3 36.Qxc5 followed by a7, which also seems to win.|
|Apr-13-13|| ||Abdel Irada: <agb>: The "etc." in your line G is a little more than I had stomach for with the white pieces.|
Here's how it might continue: 33. ...Rxe8 34. a6, Re2 35. Kf1, Bxf3 36. a7 (36. Qf6, Re3), Be5 37. Qxc5, Rd8 and to me the position is at best only slightly in White's favor. This is only one of several lines, but in each case Black appears to have sufficient resources.
|Apr-13-13|| ||engmaged: I thought of the idea of the "ZUGZUNG" ,and so then I went to
30. Kf1 Qc6 31. Bh3 Rxh3 32. Re8 and I saw it so beautiful with two starting quite moves that i missed the nice "Zwischenzug"
32... Rh1+ 33. Ke2 Re7+ 34. Rxe7 Rxa1 and white has nothing but a lost bishop.
"ZUGZUNG" & "Zwischenzug" things were too german for me.|
|Apr-13-13|| ||Patriot: Black has the bishop pair.
30.Re8 seems very strong, threatening 31...Qa7#.
30...Qh2+ 31.Kf1 Rxe8 32.a6 Re1+ 33.Kxe1 Qg1+ 34.Ke2 Re7+ 35.Kd2
I'm not seeing a decent defense for black.
|Apr-13-13|| ||Patriot: I meant to say 34.Bf1 in my line above.|
|Apr-13-13|| ||Patriot: Ouch--I missed 34.Bf1 Re7+ 35.Kd2 Qxf2+ - a very simple check and capture.|
Houdini suggests my typo (34.Ke2) is winning for white in a really crazy line. Simplest is that after 32...Re1+, 33.Rxe1.
|Apr-13-13|| ||James D Flynn: Material is equal and both sides have threats against the opposing K. If it were Blacks move he could play d4 threatening Qh1+ and if Bxb7+ Rxb7 attacks the White Q and threatens Qh1#). If the Black Q could be forced off attacking the White Q on b6 White could play 30.a6 attacking the B on b7 and if Bc8 Qc6+ forces either B or R onto b7 when axb7#.
30.Re8(threat Qa7# ) Qh2+(if Qxb6 31.axb6+ Ba6 32,Rxh8 Kb7 and White has won a R If instead )32.Rxh8 and White has won a R in a simplified position and will win the endgame) 31.Kf1 Rxe8 32.a6 Bxa6(if Bc8 Qc6+ forces either R ob to b7 wheb axb7#) 33.33.Qc6+ Rb7 34.Rxa6+ Bh7 35.Rxa7+ Kb8 36.Qxb7#|
|Apr-13-13|| ||jokerman: What's the refutation of this line: 30. Re8 Qh2+ 31. Kf1 Rxe8 32. a6 Re1+ 33. Kxe1 Qg1+ 34. Bf1 Re7+ 35. Kd2 Qxf2+ 36. Kc3 Re3+ 37. Bd3 Rxd3++ 0-1|
Seems all forced to me...
|Apr-13-13|| ||jokerman: Nevermind, as patriot showed: 33. Kxe1 is not forced :) otherwise its a fun line :p|
|Apr-13-13|| ||vinidivici: much like a midweek puzzle.
I suspected 30.Qxh6 but if that so, the puzzle wouldnt be a puzzle.
So quickly i got 30.Re8.
Its a bit funny, that i got the right move because not of my analysis, but because there are no other moves that fit to the puzzle.
Just like i said...Qxh6 makes puzzle is no puzzle anymore.
30.Re7 also ridiculous.
Knight moves wouldnt change situation.
So whats left??? Re8, i just need analyze 4 moves ahead and thats a certainty.
|Apr-13-13|| ||cyclon: My solution in today's puzzle is ( if I do not see hallucinations ) is amazingly effective 30. Re8 and suddenly Black is out of a proper defence! After this move Black has no time for -d4 and -Qh1+, for example. White Queen can't be captured on account of 30. - Qxb6 31. axb6+ Ba6 32. Rxh8 Kb7 33. Rxb8+ and 30. -Rxe8 falls into 31. Qxh6. -Bb8 cannot move and if -Bb7 moves, White mates with 31. Qxb8X. So, the 'last' try 30. -Qh2+ 31. Kf1 Rxe8 ( what else? ) 'submerges' into 32. a6 ( a powerful pawn-move ) 32. -Re1+ ( the only way to prolong ) 33. Rxe1 ( 33. Kxe1? Qg1+ ) and now f.e. 33. -Bxa6 fails to 34. Bxd5+ mating Black and -Bb8 is still paralyzed with mate-threat Qa7X. If Black plays 33. -Qh8 to cover the back-rank, White mates from the a-file by 34. axb7+ Rxb7 35. Ra1+. Same concerns with the moves like -d4 or -f6/-f5 which gets 34. axb7+. Finally, 33. -Bc8 gets the line 34. Qc6+ Rb7 ( or 34. -Bb7 ) 35. axb7+ Bxb7 36. Ra1+ Ba7 37. Rxa7+ Kb8 38. Qc7X. Did I miss something. After 30. Re8 it's cufflinks ( combined with the 32. a6 ) for White of which I think he has several pairs already.|
|Apr-13-13|| ||chrisowen: Lines cor e8 ar it down in gauge the apple of his eye 30.re8 e1 rose a mare in b5 knight plug a cake releieth, |

|Apr-13-13|| ||cyclon: Okay, I missed Blacks 'defence' 31. -Qxg2+, but that doesn't seem to change anything. Just different finale. Maybe White could have played also 33. Kf1 instead of the simplifying 33. Qxb7+, but if there's straight winning-line in sight why not to play it.|
|Apr-13-13|| ||devere: 30.Re8!! is a beautiful move.
Black start to go astray with 17...exd5? instead of a6!, and then lost with his sacrifical idea 21...Bf6? which was just too slow.
|Apr-13-13|| ||amosianboy: <Indoknight>...40Rh1 or 40 Re1 ...Ka8!escapes|
|Apr-15-13|| ||kevin86: A wild one...to say the least!|
|Apr-15-13|| ||kevin86: There is no way to combat the oddest and grandest threat of 40 axb8=♖#.|
cornered by two rooks in a very unique position!
|Feb-25-17|| ||Eusebius: A hell of a game! Sharp.|
|May-12-17|| ||ChessHigherCat: 39. Rf8 is a classy refinement allowing the promotion Qb8 with double check and mate|
|May-12-17|| ||The Kings Domain: The good old days.|
|May-12-17|| ||protonchess: Yes, they knew how to play when I was a young lad :-(|

<White's attack looks to have stalled, and if Black manages to push ... d5-d4, he can feel confident about the future ...> 1. Re8!! <A multi-purpose move: the deadly Qa7# is threatened, and simultaneously White disrupts the coordination of the black pieces on the h-file and forcibly transposes into a won ending.> Qh2+ 2. Kf1 Qxg2+ <2 ... Rxe8 loses quickly to 3. a6.> 3. Kxg2 d4+ 4. Qxb7+ Rxb7 5. Rxh8 Rxb5 6. a6 <The exchange of tactical blows has been completed, but energetic play is still demanded of White, to prevent Black from advancing his queenside pawn trio.> Ka7 7. Rf8 Rxb2 8. Rxf7+ Ka8 9. a7 c3 10. Rf8! <Accurate to the end; Black Resigns.>
<Re8 is offensive, it threatens Qa7> It was very offensive to Ivanchuk.
|Jul-01-19|| ||Dave12: Didn't read all of the comments above. My engine shows that after 22..♗xh4 white wins the bishop and the game on the spot with 23.♕e5+. Point being that after ♔a8 ♕c7 white has no time to retreat with the bishop, he must play ♖c8 to avoid ♕a5+ ♔b8 ♕a7+ ♔c8 ♕xc5+ and black's position is crumbling down. So now after 24.♖c8 white just plays ♕a5+ ♕a6 ♕xa6+ and takes the bishop next and gets a totally won game.|
