Jan-30-04  catfriend: The queen can't do it! The bishop still exists, check again!
Jan-30-04  pogo5: The variation 28...Rh2+ does not work imo: 28...Rh2+ 29.Kxh2 Bg1+ 30.Kg2! and if 30...Rh8 then and only now 31.Rxg1
Jan-30-04  ellipotrix: Good, pogo5 I agree.
Jan-30-04  pogo5: In the variation 28...Rh2+ I just discussed, the queen never gets a chance to land on f2. 28...Bg1! is needed to deviate the white rook.

  patzer2: The clear solution to today's puzzle (...28?) is 28...Bg1!! 29. Rxg1 Rh2+! 30. Kxh2 Qf2+ 31. Rg2 Rh8#.

The combination of tactical themes in this problem (...28?) is instructive, employing (1) a mate threat (28...Bg1!! threatening 29...Rh2#) to deflect the White rook to g1, (2) a deflection sacrifice (29...Rh2+) to deflect the White King to h2, (3) a Queen check (30...Qf2+) to deflect the White rook to g2 and (4) a sort of weakened back rank mating theme on the side of the board (h file) with 31...Rh8#.

Combination solution (28...?) = deflection (28...Bg1!!) + deflection (29...Rh2+) + deflection (30...Qf2+) + mate (31...Rh8#).

  kevin86: Here is a great example of how move order CAN count for a great deal. 28...Rh2+ does not work!
Jan-30-04  ughaibu: Same yesterday, Qg6 wouldn't work before Nf5, in fact how many next move problems are there in which move order doesn't matter?
Jan-30-04  WMD: Fashion plays a part even in the field of tactical motifs. Prepare for a rash of rook sacs on the h-file, both sound and unsound.
Jan-30-04  Thunderbunny350: My complements, this was a fresh, fascinating, and instructive puzzle. Bg1 is one of the prettiest wins I have seen in quite some time.
Jan-30-04  Jhony: Good Puzzel
Jan-30-04  caseyclyde: This may sound silly but I don't think it's a forced mate. Anyone want to run 29. Be3 through a computer.

If 29...Rh2+ then 30.KxB and both queens are under attack. If 30... QxB+ then white can take blacks rook.

If 29...BxB then white can play 30. Rh1 and challenge on the H file.

Granted, white is down a whole lot of material and his king is very exposed but I don't see a mate. A loss - yes, a mate - maybe not.

Jan-30-04  caseyclyde: maybe after 29.Be3 Qxe3 30.Rf2 (if 30.Rxg1 then Qf3 is mate, meanwhile white has to stop the threat of mate on h2) 30...Bxf2 31. Qxf2, Rh2+ 32. Kxh2 Qxf2 threatening mate on h8 after all.
Jan-30-04  Calchexas: Ughaibu: Very few. Good point. I might add that I see most of the solutions to these backward first, but reject them.
Jan-30-04  ughaibu: I think the idea of "seeing backwards" is interesting. I've been looking at some of Tal's combinations and they seem to be distinguished from other players' combinations by their schematic quality, as if he was thinking backwards from a projected arrangement of pieces.
Jan-30-04  Flyboy216: Apparently the most white can hold out is:
29. Be3 Qxe3 30. Rf2 Bxf2 31. Qd3 cxd3 32. f5 Qxg3+ 33. Kf1 Rh1#
Jan-30-04  ajjassi2003: not even 29.Be3 Qxe3 30.Rfe1 (trying to give the White king an escape square doesn't work either) Rh2+ 31.Kf1 Qf3+ and mate following...it doesn't work here either...i tried looking at 29.Be3 too, but it just doesn't help White's poorly placed king...

  Reisswolf: Woohoo! I must be getting better and better. I got both the last one (the Alekhine one) and this one relatively easily!
Jan-31-04  caseyclyde: What about 29.Be3 Qxe3 30.Rf2 Bxf2 31. Qe2 which seems to stop all forced mates.

  Reisswolf: But then Black is down a rook. He is definitely lost. It's not enough to stop the forced mate right away. Black must also have a playable game to continue.
Jan-31-04  catfriend: White, you mean?
Jan-31-04  caseyclyde: Reisswolf, I completely agree with you but it's interesting that, the more people examine the position, the more options are uncovered. The discussion here went from "it's a forced mate" to "it's a clear win." We all have seen games where people resigned in a winning position. This is certainly not one of them but the point is that, the more we look, the more we find.
Jan-31-04  matein8: <<caseyclyde> What about 29.Be3 Qxe3 30.Rf2 Bxf2 31. Qe2 which seems to stop all forced mates.>

Then Black continues 31...Qxg3+ 32. Kf1 Rh1#.

Dec-30-05  atripodi: What if 27.Kg3 rather than g3?
Dec-30-05  aw1988: If Kg3 Bxc3 and Nc5.
Dec-30-05  Kangaroo: <<atripodi>: What if <27.Kg3> rather than g3?>

Consider <27. Kg3 Nf6> followed by <28 ... Nh5+> if necessary. Perhaps the move <Rc8-h8> can be also included to intensify the attack.

It is agreeable that <27. Kg3> did not get such a decisive response as the suicidal via <27. g3>
