Oct-13-06  johnnyfroaction: i figured the night had to take but i was wondering if white could force a perpetual with 25. Na6+? 25...Kb7 26.Nc5+ etc... but not 25. Ka8 Qxc6+ 26 Qb7 thoughts?
Oct-13-06  johnnyfroaction: to further this line 25. Ka8 Qxc6+ 26 Qb7 Nxa6+ Ka8 27. Qxb7+ Kxb7 28. Bxh2 thoughts?
Premium Chessgames Member That's one of the prettier points of this combination: 25.Na6+ Qxa6!!
Oct-13-06  chessmoron: <johnnyfroaction> 25. Na6+ Qxa6 then what will white do, take queen 26. Qxa6 then 26...Nxf1+ 27. Bh2 Rxh2#
Oct-13-06  syracrophy: Charming! I really failed at this one, and I liked <> variation: <25.Na6+ Qxa6!!> It's amazing! Check that if <25.Na6+ Ka8 26.Qxc6+ Qb7 27.Qxb7+ Kxb7 28.Nc5+ bxc5 29.Rab1+ Kc8 30.Bxh2 and white wins>

That's the idea: black needs to eliminate the check with tempo <25...Qxa6!!> as the White queen has to capture the black queen, or escape as well, and also, has to avoid <26...Nxf1+ 27.Bh2 Rxh2#> as well

That's why 25...Ka8? loses outright

Oct-13-06  Ashram64: the domino effect combination.. first thought... Rxh2+, but that dont force anything. Nxh2..and saw Na6+ is useless

decently tough puzzle

Oct-13-06  ksh123: Beautiful! I wonder how these players can thing that ahead...

  al wazir: How does black win after 29. Ke3 ? The best I can find is 29...Qg5+ 30. Rf4 Rh3+ 31. Ke2 Qxf4 32. Nd3.

After 29.Ke3 Qg3+ 30.Rf3 f4+ 31.Kd4 Qxf3#

  al wazir: <syracrophy: 29.Ke3 Qg3+ 30.Rf3 f4+>. Of course. I tried 29...f4+, and when that didn't work I gave up on the ♙. Thanks.
Oct-13-06  Sami Jr: Wow, what foresight Bonin has! Multiple lines could have panned out after 24...Nxh2 with several branches following each line. I played out (on the board) every different response white could have taken and all of them eventually lead to a forced mate when black plays the right followup moves. For Bonin to have calculated all the possible branches in his head to ensure that a mate was guaranteed no matter which line was taken is truly amazing. It's extremely hard to believe that he's not a GM. This has to be the best puzzle I've seen in a while.
Oct-13-06  dzechiel: Saw it up to 30...Qxc3. However, once you are in that far, there's no turning back.
Oct-13-06  dfelix: I bit on 32.Nxd4, but 32...Qe8+ 33.Kb7 Nc5+ 34.bxc5 Qb5+ draws.
Oct-13-06  johnnyfroaction: thanks <>, it seems so obvious now.
Oct-13-06  Confuse: doh. crazy cool combo here : )
Oct-13-06  Marco65: I think I solved it, but with less brilliant moves.

First of all, if 25.Na6+ Kb7 (I missed the brilliant 25...Qxa6!) 26.Nc5+ Ka8 27.Qxc6+ Kb8 28.Nd7+ Qxd7! (strange I found this and not 25...Qxa6!). Or 28.Na6+ Qxa6 29.Bxh2 Qe2.

Then, instead of 26...Rh8+ I thought of 26...Qe8, it's less forcing but should win as well:

a) 27.Rf3(f5) Qg6

b) 27.Na6+ Kb7 28.Nc5+ Ka8 29.Qxc6+ Qxc6 or 29.Qe2 Qg6 28.Qf3 Rh8+ 29.Qh6 Rxh6+ 30.Kxh6 bxc5 but I admit winning in these lines is still not an easy task

Oct-13-06  ahmadov: <syracrophy> Can you notice that this puzzle is very much alike of the one you posted on my forum last time?
Oct-13-06  eaglewing: I'm still looking for the kill in case of 28. Kf3.

A) 28. Kf3 Rh3 29. Ke2 Rh2 30. Kd1 loses Black a tempo compared to the game, which the White King uses to flee to d2/d1/c1. 29. ... Qg4/g2 seems not better.

B) 28. Kf3 Qg4 29. Ke3 (Kf2 Qg3 leads to the game) and now:

Rh3 or f4 anwered by Kd2
Rh2 allows regrouping Nd7 and Qxd5
Qg3 Kd2 Rh2 Kc1 Qc3 Qb2 is not enough.

Best seems:
Qg5 Ke2 Rh2 Rf2 Qg4 Ke1 Qg3/h4 (Qg1 Qf1 or Rh1 Rf1 Qg3 Kd1/d2), which should regain a rook with Qg3/h4 Qe2 Rh1 and xRa1. Or if Qg3 Qf1, then Qe3 Qe2 Qxc3 Qd2 Qxa1 Ke2.

Where is a more forcing idea for Black? Did I overlook something easy?

Oct-13-06  Marco65: <dfelix> Also 32.Nxd4 should win: 32...Qe8+ 33.Kb7 Nc5+ 34.bxc5 Qb5+ 35.Nxb5

33.Qxd5 is rather surprising, although of course also 33.Qxa6 Qc3+ 34.Kd1 Qxb3+ 35.Ke1 Qc3+ 36.Kd1 Qd2 mates

Oct-13-06  ceebo: <eaglewing: Rh2 allows regrouping Nd7 and Qxd5> but then 30... f4+ 31 Ke4 f5+ 32 Kd3 Qe2#
Oct-13-06  Fischeristhebest: <eaglewing> 29.Kf3 Qg4+ 30.Ke3 Qg3+ 31.Rf3 <f4+> 32.Kd3 Qxf3#.
Oct-13-06  eaglewing: You are right <ceebo>. On <28. Kf3 Qg4 29. Ke3 Rh2> is decisive:

30. Nd7 Kc8 31. Qxd5 f4+ 32 Ke4 f5+ 32 Kd3 Qe2# <by ceebo>.

30. Ne6 Qe4#
30. Rg1 f4 Kd3 Qf3#
30. Rae1 Qg3 Rf3 f4 Kd3 Qxf3 Re3 Qd1#
30. Rf2 Qg3 (Rf3 f4 ...) Ke2/d2 Qxf2+ and mate soon.
30. Rf3 Qg5 (Kd3 Qd2#) Rf4 Qg3 Rf3 f4 ...
30. Rf4 Qg3 Rf3 f4 ...
30. Rxf5 Qg3 Rf3 Qg5 Rf4 Rh3 Ke2 Qxf4 and the threats Qe3 and Rh2 decide.

<Fischeristhebest> You mixed up the lines in your comment. The line 28. Kf3 means Rh2 is not yet played.

Oct-13-06  eaglewing: Nice line by the way, <ceebo>. Maybe there is even another solution, but it astonishes me, that even the Pawn f6 is needed here in this line.
Oct-13-06  euripides: Marco <Then, instead of 26...Rh8+ I thought of 26...Qe8, it's less forcing but should win as well:

a) 27.Rf3(f5) Qg6

b) 27.Na6+ > now simply 27....Kc8 seems to do the job.

Oct-13-06  Marco65: <euripides> 26...Qe8 27.Na6+ Kc8 is not simpler, because you need to find how to win in the line 28.Qe2 Qg6 29.Qf3 Rh8+ 30.Qh3 Rxh3+ 31.Kxh3 and now the white knight is not "en prise". Probably 28...Rh8+ wins again, but in this case why not playing it at move 26 as in the text?

I was trying to leave the king trapped on the h-file and make it work because I felt that was simpler to calculate, and the discussion on 28.Kf3 seems to support my point.
