Feb-17-06		makaveli52: beautiful ending, found it immidietly and saw the line all the way to Kg7 easily. Got to love endgames

Feb-17-06		blingice: I saw this one very quickly. Drawing the ♔ away from something you want to promote is pretty obvious to me...

Feb-17-06		dac1990: I said 83. h7, with the idea of 83 ...Kxh7 84. Rg5, preventing the king from helping to block the remaining f-pawn. Anyone care to comment?

Feb-17-06		Kangaroo: If <83. h7> then <83 ... Rf6+ 84. Ke7 Rxf7+> which leads to a draw. Or <83 ... Rf6+ 84. Kd5 Kxh7> and draw is most likely to occur.

Feb-17-06		yataturk: Wow, got a Friday puzzle.. I saw it upto 85 and assumed it'd be a white victory from that point on.

Feb-17-06		LluviaSean: yess. got this one..bring sunday on!!!

Feb-17-06		chesswonders: I thought 83. ♖f5 wins. If 83. ... ♖xf5, then 84. h7! wins. But black can repeat the position with 83. ... ♖e1+ 84. ♖e5 ♖f1

Feb-17-06		dzechiel: Stared at this position for over five minutes and never considered the key move. I got hung up on 83 ♖f5 followed by 84 h7, but that line turns out not to work. Maybe tomorrow. <sigh>

Feb-17-06		inad: Is a queen vs a rook a given win?

Feb-17-06		Ger7ry: I thought Black could beat this with 83 Rg5+ Kxh6 followed by keeping the White King in check, but now I see it doesn't work. White may not be able to win by tucking his King in behind the f-pawn, but he can come after the Rook, instead. E.g., 84 Rg8, Re1+ 85 Kd5, Rd1+ 86 Ke4 etc, and soon Black is out of checks.

Feb-17-06		64 Squares: <inad> With best play the side with the queen wins.

Feb-17-06		Peligroso Patzer: With regard to the line offered by <dac1990>: After 1. h7, Black has 1. ... Rf6+, which should draw. Either White's King is driven away from defense of the P/f7 (2. Kd5), or (after, e.g., 2. Ke7) Black takes the f-pawn with check and then takes the h-pawn.

Feb-17-06		chesstoplay: Queen beats rook within the 50 move rule always... unless there is a specific positional start to the endgame that is critical or, of course, a simply human fatal blunder.

Feb-17-06		patzer2: For today's puzzle solution, Ivanov's decoy 83. Rg5+! Kxg5 (or deflection after 83...Kxh3 84. Rg1!) 84. h7! sets up a winning passed pawn combination.

Feb-17-06		buRnINGbeNd: It seems to me that this wouldn't actually be Q v R, but QQ v R as black can't stop either without giving up his R. So logically the continuation would leave KQ v K, which is a very easy win, and definitely within the 50 move rule.

Feb-17-06		LIFE Master AJ: Nice play ... I got it after a couple of minutes ... but only after trying almost every other possible move.

Feb-17-06		who: Even if 85...Kg6 86.h8=Q Kxf7 87.Qh5+ white will win the rook with a king rook fork on the e1-h4 diagonal so that too isn't good enough to get a QvR ending. In case someone's wondering if 83.Rf2 Rf6+ (83...Rxf6? 84.Rg2+ ) draws.

Feb-17-06		patzer2: <buRnINGbeNd:> Right! In fact, on second look I like 83...Kxh3 84. Rg8! for avoiding 83...Kxh3 84. Rg1 Rxg1 85. f8Q+ with a Q vs. R ending.

Feb-17-06		Fezzik: The old rule for puzzles, look for the biggest piece and sacrifice it somewhere works here. A. Ivanov's endgame play was truly special, and the tactical finish just made it sweeter. Great play by Ivanov, but I wonder where Black went wrong in the theoretically drawish position that arose by move 60.

Feb-17-06		chessgames.com: It's hard to estimate how difficult this puzzle is but it definitely deserves extra-credit for "beauty." We saved it for Friday for that reason alone.

Feb-17-06		Deefstes: This is my second Friday puzzle in a row! Am I getting better or are the puzzles getting easier? Probably the latter.

Feb-17-06		LoFarkas: <chesswonders>: 83. Rf5+ Rxf5 84. h7 Kxh7 85. Kxf5 Kg7 86. Ke6 Kf8 87. Kf6 stalemate.

Feb-17-06		wzeller: Black can't answer with 83. ... kxh6 because white has 84. rg8 re1+ 85. kd5 rd1+ 86. ke4 re1+ 87. kd3 rd1+ 88. ke2 and black is out of checks allowing white to promote on f8 and forcing black to lose his rook to recapture leading to an easy r+k v. k win for white.

Feb-17-06		pwrstick: Hmmm, I thought my solution was better (lol, humbly lol): 83. Re3 See, I was under the assumption that given 83. Rg5+ that ...Kxh6, in which case black could force a draw. But if 83. Re3 Rxf7, black loses rook (84. Rg3+ Kh? 85. Kxf7) and white wins. Alternatively, 83. Re3 Kxh6 84. Ke7 Kf6/7 85. Rf3+ Kh? 86. f8 There are several iterations of that alternative, but they all end up with the pawn promoting, and the black rook forcing itself to sacrifice. Then white is, again, up a rook and it's win time! So, I humbly submit to you brains bigger than mine: did black error? If I were black: click for larger view And if I were white click for larger view

Feb-17-06		pwrstick: Ah, OK I see that the 83...Kxh6 is wrong. Do you think my other solution works too though? 83. Re3?
