< Earlier Kibitzing  · PAGE 2 OF 2 ·  Later Kibitzing>
Feb-01-09  crwynn: I only looked at 30...Qb6, where I saw the idea of getting a discovered check by Ne5 as in the game, with the q on b6 this means nc4 will win. I thought there was no point in looking at lines where Black hangs b8, but in the game 33.Nb8 Rd6 actually looks bad for White.
Feb-01-09  Samagonka: I got the first move surprisingly quick, the rest is too long a combination for me.
Feb-01-09  Granny O Doul: 37. Nf3+ is a bit simpler and quicker.
Feb-01-09  Open Defence: I didnt find this as insane and the usual week end ones
Feb-01-09  FabrikaLaHun: I think it was pretty easy to see the focus of the attack would be on e5. Choosing which piece to attack with was the lesson I learned here. I liked 28 Nxe5+ b/c it is forcing but after ...fxe5 and 29 Rxe5 it seems the attack stalls.

What I liked about the played line was moves 30 Nc6 with the fork of rook and Queen (which I didn't see from the initial puzzle position), Black's response of 30...Qh5 saving both his queen and getting back his rook if white takes at b8 and then 31.Qh8+.

I'll have to admit that OTB, after 32.Re1+ removes the rook from the Black Queen's sights, I would have taken my Rook back with 33.Nxb8.

Feb-01-09  tallinn: <whitebeach: up to g4> Interestingly enough g4?! is not the best move as white has a forced mate in that position starting with Qf6, the threat being Nxg6+ and Qf8#. Black can prolong its agony by throwing pieces at white only: Qd1 Rxd1 Ne6 Qxe6 Kf8 Nxd7 and so on. g4 is not even second best: Nxd7 and Qg8 are better as well.

After g4 Qxh3? white missed another forced mate starting with Nf3+ (Kf7? Ng5#) Re7 Rxe7+ Kd8 Qxf8#.

Although Nc6 is stronger, Rxe5 fxe Nxe5 Ke8 Nxd7 Kxd7 Qf6 wins as well. Thus this problem is rather easily solved.

Blacks best defense on Rxe5 is not to take: Rxe5 Qb6 and now the best move Red5 gives an evaluation of +0.92 only.

Feb-01-09  melianis: I'm silent before this.

  johnlspouge: Sunday (Insane):

O Garcia vs J M Bellon Lopez, 2001 (28.?)

White to play and win.

Material: Even. The Black Kf7 has 4 legal moves. White has an advanced passed Pd6 backed by Rd1. The White Re4 is on a semi-open file and a semi-open rank. The White Qb2, Re4, and Nf3 attack Pe5, which is protected by Qa5 and Pf6. Because the Black Qa5 and Rb8 are distant, a sacrificial attack against Pe5 might be based on local superiority around the Black K-position. The Black Kf7 would then be open, and all Black pieces except Ne6 are loose and susceptible to Q forks. The Black Qa5 is somewhat cramped, with only 3 flight squares. The White Kg1 is secure from checks.

Candidates (28.): Nxe5+, Ng5+, Rxe5

The N is better left standing at e5 than the R, because White then has a strong initiative against the open Black K.

28.Rxe5 fxe5 [else, drop a P]

29.Nxe5+ Ke8 [else, drop 2Ps after 30.Nxd7]

<[I went for 30.Nxd7, which Toga evaluates at about +2.0 Ps, not as good as the game variation 30.Nc6, but still winning.]>

30.Nxd7 Kxd7 31.Qf6 (threatening 32.Qe7+ 33.Qxe6)

Because counterattack is infeasible, Black must reinforce or move Ne6 (feasibly, only to d8 or c5).

(1) 31Re8 32.Qf7+ Kd8 33.d7 (threatening 34.dxe8=Q# and 35.Qxe6)

33Re7 34.Qg8+ Kc7 35.Qxe6 (threatening 36.d8=Q+ 37.Qxa5)

Black is down at least a Q.

(2) 31Nd8 32.Qe7+ Kc6 [Kc8 33.Rc1+] 33.Rc1+ Kd4 34.Qc7

34Qb6 [else, drop material] 35.Rd1+

35K to e-file 36.Qe7+ Ne6 [Kf5 37.Rd5#] [Kf3 37.Rd3+ Qe3 38.Rxe3#]

37.Re1+ and Black is down 2P after 38.Qxe6

<[Toga gives the next variation as best play after 30.Nxd7, up to 34.Qd6+, when it prefers 34.Nd6+.]>

(3) 31Nc5 32.Qe7+ Kc6 [Kc8 33.d7+] 33.d7 Rd8 34.Qd6+ Kb7 35.Rd5

35Rxd7 36.Rxc5

White has won a P.

(4) 31Qf5 32.Qe7+ Kc6 [Kc8 33.d7+ then 34.d8=Q+]

33.d7 (threatening 34.Rd6+ Kc5 [Kb7 or Kc7 35.d8=Q+] 35.Rxe6+)

(4.1) 33Nd8 34.Qd6+ Kb7 35.Rc1 (threatening 36.Rc7+ 37.Qxa6#)

35Ka7 36.Qc7+ Nb7 [Rb7 37.Qxd8] 37.a5 (threatening 38.Qb6+ 39.Qxa6#]

There is no antidote.

(4.2) 33Qe5 34.d8=Q Rxd8 35.Rxd8 Qa1+ 36.Kh2 Nxd8 37.Qxd8

White wins a P and is likely to win against the open Black K and the remaining weak Ps.

Feb-01-09  Confuse: In my opinion, 34. Nxg6+ leads to a happier line... but it all wins, so whatever : )

neat.

  agb2002: The first move I considered was 28.Nxe5+ but 28.Rxe5 seems stronger:

A) 28... fxe5 29.Nxe5+

A.1) 29... Qxe5 30.Qxe5 followed by Rd3-f3.

A.2) 29... Ke8 30.Nc6

A.2.a) 30... Qb6 31.Qh8+ Nf8 (31... Kf7 32.Ne5#) 32.Re1+ Re7 33.Rxe7#.

A.2.b) 30... Rxd6 31.Rxd6 Qb6 32.Qh8+ Nf8 (32... Kf7 33.Rd7#) 33.Qe5+ Kf7 34.Rf6+ Kg7 (34... Kg8 35.Ne7+) 35.Rxf8+ Kxf8 36.Qf6+ and mate next move.

A.3) 29... Kg8 30.Nxd7 Rd8 31.Qf6 Rxd7 32.Qxe6+ Rf7 33.d7 winning.

A.4) 29... Kf8 30.Nxd7+ and 31.Nxb8 .

B) 28... Qxe5 29.Nxe5+ fxe5 30.Qxe5 as A.1).

C) 28... Qb6 29.Red5 Rbd8 30.Qd2 and White is at least pawn ahead.

This is all I have today (Ive been watching Wang Yue vs Carlsen, 2009).

Feb-01-09  drnooo: Right, hardly insane. In fact way down the line doesnt queen takes knight, king takes queen, knight takes rook check then knight takes the other rook in a series of forks also win: if so this is doubly not insane.
Feb-01-09  vijaymathslpjz: oh my @#$%in god..........this is insane indeed.first time im trying an insane puzzle...too much i say
Feb-01-09  drnooo: on the 34th move, now that I double check, queen takes knight wins the house also:in fact this one is a good deal easier than some of the thurs or fridays, but still pleasant
Feb-01-09  drnooo: In fact now that I triple check, on the 34th after queen takes knight, g4 doesnt even come into play, this looks like an even shorter solution, right? pawn goes to the seventh and black has to turn over his king
Feb-01-09  jovack: Knight or Rook to e5 was very apparent. Taking with the rook first has a more interesting game.

  DarthStapler: I at least considered the first move
Feb-01-09  njchess: I got Rxe5, but I thought this led to perpetual check. 36. g4 is a bit of inspired play. 36. ... Qh6 is a better alternative to Qxh3??, which only removes the queen from Black's game.
Feb-01-09  soberknight: Wow that's a crazy ending. I thought Nxe5 but saw nothing. I didn't even try Rxe5, didn't see the obvious knight fork, certainly not the other fun stuff.

Gotta go watch the Super Bowl!

Feb-01-09  WhiteRook48: I thought Ng5 thinking maybe that, but didn't see Rxe5. I can never solve these Sunday puzzles
Feb-01-09  patzer2: For today's four-star difficulty and Super Bowl Sunday puzzle solution, White wins with the deep sham sacrifice 28. Rxe5!! which initiates a deep winning pursuit (King Hunt) combination.

P.S. Congratulations to the Pittsburg Steelers on winning the Super Bowl and to the Arizona Cardinals for playing a great game.

Feb-01-09  DwayneMeller: saw 28Rxe5 fxe5 29Nxe5+ Ke8 instantly and relaized that 30Nxd7 leaves white with only two pieces left then I looked quickly(about 20 seconds at moves on 28) and realized 28Rxe5 is the only logical candidate (28Nxe5 fxe5 looks insufficient) and looked at 28Rxe5 fxe5 29Nxe5 Ke8 30Nc6 Qb6 31Nxb8 Qxb8 32Qh8 (32...Kf7 33Qxb8) Nf8 33Re1+ (33...Kd8 34Qxf8#) Re7 34Rxe7+ Kd8 35Qxf8# I didn't find the game continuation (but then again I didn't look for it...am very tired just got thru watching the Super Bowl...may I echo patzer2's words) but I'd play Rxe5 Otb and work out other queen moves to guard against sneaky defenses OTB but seeing this is a puzzle and finding the justification and not having the stamina (am going to bed after this post) I did not look for other moves (sometimes you can't work it out otb and you play on instinct but I always like to be sure ...and if I find no refutations...on a straightforward easy position like this I go for it quickly as I said I found it instantly...in a complicated mess I take my time to avoid being refuted but if its an unclear muddying of the waters I'll still go for it as long as I find no refutation (I play all types of chess) but in a puzzle justification is usually all you need to know what's right...and it helps you to sharpen your "real chess" abilities...for when justifications don't always do due to refutations ...goodnight dudes and chicks...
Feb-01-09  SmotheredKing: I saw 28. Rxe5 fxe5 29. Nxe5+ Ke8 30. Nc6 but I assumed black would try to protect the rook with either 30... Qb6 or ... Qd8, after which there follows 31. Nxb8 Qxb8 32. Qh8+ Nf8 33. Re1+ and wins. ...but on second thought, 33. ... Kf7 and white has no good continuation, so the game is definitely better
Feb-01-09  SmotheredKing: although this leaves me puzzled... if 30. ...Qb6 or ... Qd8 , intending 31. ... Qxb8, what is whites refutation?
Feb-02-09  patzer2: <SmoptheredKing> I'm currently without a Chess Engine to verify, but after 30...Qb6 White could try 31. Qh8+ Nf8 32. Re1+ Kf7 33. Ne5+ Ke8 34. Ne5+ .

If 30...Qd8, I'd think 31. Nxd8 would work. However, also possible is 31. Qh8+ Nf8 32. Re1+ Kf7 33. Ne5+ Ke8 34. Ng4+ Kf7 35. Nh6#.

May-04-09  butilikefur: <28. Rxe5 fxe5 29. Nxe5+ Ke8> (After 29...Qxe5 30. Qxe5 an interesting possibility is 30...Re8 31. Re1 Nc7 32. Qf4+ Kg7 [32Kg8 33. dxc7 Rxe8+ 34. Kg2 Re8 35. Qc4+ wins] 33. Qd4+ Kf7 [33...Kf8 34. Qh8+ Kf7 35. Qh7+ Kf8 36. Rxe8+ with Qxd7 or Qg8+ mate] 34. Qc4+ Ne6 [34...Kf8 35. dxc7 Rxe1+ 36. Kg2 - White wins] 35. Qc6 Ra7 [35...Nc5 and 35...Rd8 are met by 36. Qf3+] 36. d7 wins)

<30. Nxd7 Kxd7 31. Qf6 Qf5> (31...Re8 32. Qf7+ Kd8 33. d7 Re7 34. Qg8+ Kc7 35. d8=Q+ Nxd8 36. Qxd8+ wins the Black queen)

<32. Qe7+ Kc6> (32...Kc8 33. Rc1+ mates)

<33. Rc1+ Kb6> (34Kd5 35. d7 Rd8 36. Rd1+ Kc6 37. Qd6+ Kb7 38. Rc1 Qe4 39. a5 and White is winning)

<34. d7>

Now Black has a couple options:

A) <34Rd8 35. Qd6+ Kb7> (35Ka5 36. Rc6 [36. Rc8 threatening Rxd8 Nxd8 Qc7+ mate also looks winning, for example, 36Qb1+ 37. Kh2 Qxb3 38. Rxd8 Nxd8 39. Qc7+ Kxa5 40. Qxd8 Qf3 41. Qb6] 36Ra8 37. d8=Q+ mates)

<36. Qxb4+ Ka7 37. Rc8> is winning for White

B) <34Qe5 35. d8+> (35. Rd1 Kc6 36. d8=Q does not work because of 36Rxd8 37. Rxd8 Qe1+ 38. Kh2 [38. Kg2 Nf4+ 39. gxf4 Qxe8] 38Qxf2+ with a perpetual)

<35Rxd8 36. Qxb4+ Ka7 37. Rc6> wins, for example 37Qb8 38. Qe7+ Qb7 39. Qxb7+ (White has to be careful of things like 39. Rxe6 Rd1+ 40. Re1 [40. Kh2 Rh1+ mate] 40...Qxe7) 39Kxb7 40. Rxe6 Rd3 41. Re3 and White has a won endgame.
