Aug-15-13		Conrad93: This is not worth the three star rating. I spotted this within a few seconds.

Aug-15-13		piltdown man: Wow, I found it.

Aug-15-13		morfishine: Its like eating a bag of Doritos <25.Rxf6> Crunch 25...Rxc7 <26.Rf8+> Crunch 26...Rxf8 <27.Qxe5+> Crunch *****

Aug-15-13		The HeavenSmile: <once> haha, once again, a great story! I was recently told that you need a permit from the king before you are allowed to build crenelations on you castle towers, i wonder if chess pieces need them too?

Aug-15-13		Willem Wallekers: I was expecting 25. Rxf6 Qg1+ 26. Rf1 <Qxh2. 27. Nf4>. Seems that white is winning a piece at least.

Aug-15-13		cyclon: A nice Puzzle Today, somewhat 'polymorphous'. I'll start with 25. Rxf6 and now some illustrations; 1. -25. -Qd6 ( 25. -Qg1+ 26. Rf1 wins ) 26. Rxd7 Qxd7 ( or 26. -Rxc3 27. Rxd6 White is piece and pawn up, neither 26. -Nxd7 27. Rf8X, or 26. -Qxe6 27. Qxc8+ works ) 27. Qxe5 and if -27. -Kg8, then 28. d6 is strong. 2. -25. -Rg8 ( 25. -Rd8/Re8 gets 26. Rf8+ mating ) 26. Rxd7 h5 ( or 26. -h6, but 26. -Rac8 27. Rxh7+ Kxh7 28. Qh3X. Also on 26. -Rg7 White can play either 27. Rxg7 or 27. Qxe5 and even 27. Rff7 ) 27. Rff7 Rg7 28. Qxe5 Qe3+ 29. Kf1 White escapes checks. Maybe there's a faster way. 3. -25. -h5 26. Rf8+ Kh7 ( 26. -Rxf8 27. Qxe5+ mates ) 27. Rxd7+ Kh6 ( or 27. -Nxd7 28. Qg7X ) 28. Qd2+ g5 29. Qxg5X. 4. -25. -Rxc7 26. Rf8+ Rxf8 27. Qxe5+ with mate to follow. 5. -25. -Bxe6 26. Rf8+ Rxf8 27. Qxe5+ likewise mates. 6. -25. -Nd3+ 26. Kd1 and -26. -Qg1+ loses to 27. Rf1+. 7. -25. -Kg8 26. Rxc8+ Rxc8+ 27. Qxc8+ Bxc8 28. Rf8X.

Aug-15-13		cyclon: <Patriot:> To your line <25...Qxc7 26.Rf8+ Rxf8 27.Qxc7 > White can simply play ( 25. -Qxc7 ) 26. Nxc7.

Aug-15-13		cyclon: Couple of focusing resolutions are worth mentioning; -25. -Qg1+ 26. Rf1 Qxh2 White mates as I mentioned in the line "7." , namely 27. Rxc8+ Rxc8 28. Qxc8+ Bxc8 29. Rf8X. Another one is; -25. -Rg8 26. Rxd7 and if NOW; -26. -Qg1+ 27. Rf1 Qxh2, then quietly 28. g3 and it's all over.

Aug-15-13		cyclon: .....and, forgive me my immodesty, but just in case someone still wonders why I say "it's all over", one line after 28. g3 could be ( if Black wants to prolong the agony ) -28. -Qh5 ( to cover the -Ne5 ) 29. Rf5 Qh1+ ( 29. -gxf5 30. Qxe5+ ) 30. Kd2 Qxe4 ( 30. - Qg2+/Qh2+ 31. Kc1 and White King escapes to a3 ) 31. Rxe5 Rgc8 ( 31. -Rac8 32. Rh5+ mates next ) White mates either by 32. Rh5+, or 32. Rxh7+ Kg8 ( 32. -Kxh7 33. Rh5+ mates next ) 33. Rg7+ Kh8 34. Rh5+ gxh5 35. Rg8++ Kh7 ( 35. -Kxg8 36. Qg7X ) 36. Qg7X.

Aug-15-13		kevin86: The main tactic was to clear the long diagonal;the queen certainly knows how to use it.

Aug-15-13		ajile: I saw the first few moves but not the final Rf8+ which clears the long diagonal with tempo. Pretty slick combo.

Aug-15-13		zavariz: Just Great !!!

Aug-15-13		MiCrooks: A line I didn't see discussed after Qd6 is the immediate Rf8+. Since Rxd7 works fine as shown above, I guess looking for slightly better results may be moot, but this line does not give Black the chance to go into his "best" line with Rxc3 where he is "just" a bishop and pawn down. He has to continue to deal with the mating threats. After Rxf8 NOW play Rxd7. If Black plays Qxd7 he is back into crushing lines from before with moves reversed e.g. Qxe5+ Kg8 d6! So instead Black has to try something like Rac8. After Nxf8 this can lead to the same ilne as before with Rxc3 Rxd6 Re4+ etc, but Black has another try which leads to a really cute position. After Nxf8 Qxd7 seems better since the Knight no longer attacks g7. Qxe5+ Qg7 looks like it might actually make for an ending with some chance for Black to hold out (R vs BN). But after Qxg7 Kxg7 Ne6+ Kf6 d6! once again is the key move. The pawn's advance cannot be stopped! So the Rook will have to shortly give up it's life for the pawn. Best here is R about anywhere on the 8th rank say g8. Then e5+ chases the King away from the defense and after Kxe5 d7 the pawn gets traded for the Rook on the next move.

Aug-15-13		patzer2: <bachbeet: It seems that a better move by black is 25. ... Qd6. Seems to prevent white's mischief.> Nice try, but after 25...Qd6 26. Rxd7! Black is busted. I had thought 24...Bxe6 would save Black's game, but 24...Bxe6 25. Rxf6!! (not 25. dxe6?? Rd3! ) gives White a winning attack.

Aug-15-13		Alex56171: 25.Rxf3 looks as a good move to be analysed.

Aug-15-13		Shamot: very funny <Once>....Major Queenie........... ha ha ha ha

Aug-15-13		patcheck: 25. Rxf6 A) 25. … Rxc7 26. Rf8+Rxf8 (forced) 27. Qxe5+ Kg8 28. Qg7# B) 25. … Bxe6 26. Rf8 Rxf8 (forced) 27. Qxe5+ Rf6 (27. … Kg8 28. Qg7#) 28. Qxf6+ Kg8 29. Qg7# C) 25. … Nd3+ 26. Ke2 (better than 26. Kf1 Ne5 and things are not so easy, for instance : 27. Rf8 Rxf8+ 28. Nxf8 Rxf8+ or 27. Qxe5 Qe3+) : and black is lost : C1) 26. … Kg8 27. Rxg6+ Kf7 28. Qf6+ Ke8 29. Rg8# C2) 26. … Ne5 27. Rf8+ and white wins as we’ve seen in the B variation. D) 25. … Qg1 (25. … Qe3 + 26. Qxe3 and black has no real compensation for its queen and white follows with a decisive attack) 26. Rxf1 and black can’t deal with all the white threats. E) 25. … Kg8 26. Rxc8+ Rxc8 (26. … Bxc8 27. Rf8#) 27. Qxc8+ Bxc8 28. Rf8# Maybe are there other possibilities, but I think that 25. Rxf6 is winning for white in every line.

Aug-15-13		Patriot: <<cyclon>: <Patriot:> To your line <25...Qxc7 26.Rf8+ Rxf8 27.Qxc7 > White can simply play ( 25. -Qxc7 ) 26. Nxc7.> Very true! I vaguely remember seeing that later while reviewing it in Fritz and thought "Why didn't I just play 26.Nxc7??" I'm not too unhappy though. I found a winning sequence without a refutation which helped prove 25.Rxf6 works.

Aug-15-13		quinlan: If: 25. ...Qd6, then, 26. Rxd7!, winning.

Aug-15-13		geniokov: Are you all sure that 25.Rxf6 wins for White? How about if i play after 25.Rxf6 Qb4! So,there is no more Rf8+ by White since Qxe5+ is now impossible because of discovered check at White´s King? And if 26.Qxb4,then Nd3+ Black can also take the White Queen?

Aug-15-13		geniokov: Remember,f8 square was covered 3x by both Black rooks and Queen?

Aug-15-13		Patriot: <geniokov> I'm not sure if it's the best line but this must be winning for white: 25.Rxf6 Qb4 26.Qxb4 Nd3+ 27.Kd2 Nxb4 28.Rxd7 . White at least wins a piece in that line.

Aug-15-13		geniokov: <Patriot: <geniokov> I'm not sure if it's the best line but this must be winning for white: 25.Rxf6 Qb4 26.Qxb4 Nd3+ 27.Kd2 Nxb4 28.Rxd7 . White at least wins a piece in that line.> Correct! But at least there is no mate at all!Black resigned due to lost of piece!

Aug-15-13		Patriot: <geniokov> You asked if 25.Rxf6 wins after 25...Qb4. Being up a piece is technically winning so it doesn't really matter if there is a forced mate in sight--especially when white is rated 2700. I thought 25...Qb4 was an interesting try though!

Aug-15-13		patcheck: <geniokov> 25. Rxf6 Qb4+ (I hadn't seen this possibility) 26. Qxb4 Nd3+ 27. Kd2 Nxb4 28. Rxd7 and I don't see any good way for black to avoid : 29. Rff7 followed by 30. Rxh7+ Kg8 31. Rdg7#. The only try I see would be : 28. ... Re8 29. Rff7 Rxe5 (what else to avoid mat?e) 30. Rxh7+ (or first 30. dxe6) Kg8 31. Rdg8+ Kf8 32. dxe5 and black is totally lost.
