| May-09-06 | | TrueBlue: got it. very easy. |
|
| May-09-06 | | DoctorChess: Easy.. Saw it in an instant. Great decoy sacrifice! |
|
| May-09-06 | | DoctorChess: 35... Nc7?? A horrible move that caused Black the game. |
|
| May-09-06 | | Jarlaxle: if the only thing you have to contribute to a chess forum is that you're the first person here... THEN DON'T BOTHER <netlava> |
|
| May-09-06 | | chessmoron: mmh...interesting...I thought 38. g6 then followed by Rb3+ 39. Kf4-Rf3+ 40. Kxf3-Nxd4+ 41. Kg4-Kf8 42. Rxb7-Kg8 43. Rb8#...(Is this right?) |
|
| May-09-06 | | mrvocab: 38. g6 also wins quite nicely. |
|
| May-09-06 | | netlava: Playing g6 first is weaker because it results in mate a bit later since black can stall with Kf8. |
|
| May-09-06 | | Confuse: lol, looks like <jarlaxle> got to <netlava>. nice rook sac, i notice the king in the corner usually gets mated more often, or maybe its just because people keep castling. |
|
| May-09-06 | | notyetagm: 38 ♖h8+! is a beautiful <DECOY> into a mating net. After the forced 38 ... ♔xh8, White simply plays the crushing quiet move 39 g6, and now this <killer g6-pawn> traps the Black king on the <back rank>. Black is powerless to prevent the threatened <back rank mate>. Rooks on the 7th rank are all-powerful. They threaten 1) to whisk away enemy pawns, 2) create lateral pins/skewers/forks, and 3) create mating focal points on the 7th rank squares and threaten back rank mate on the 8th rank. |
|
| May-09-06 | | chessmoron: <netlava> by playing 39...Kf8 40. Rf7  Kg8 41. Rh8 Kxh8 42. Rf8#, so g6 is not weak |
|
May-09-06
 | | al wazir: 37. g6 Kf8 (37...Nxd4/Nxa3 38. Re8#) 38. Rf7+ Ke8 39. Rh8#. If Black checks on move 37, the white ♔ just sidesteps, as in the game. |
|
| May-09-06 | | dzechiel: Saw this one pretty quickly, just a few seconds. I would guess that the direct 38 g6 probably also wins, but 38 Rh8+! finishes black off much more quickly. |
|
| May-09-06 | | marcwordsmith: why be mean, <jarlaxle>? I might have called "first!" too if I'd been first. I liked <netlava>'s post; it was in the spirit of fun. Unlike yours. |
|
| May-09-06 | | Ger7ry: So what should Black do instead of 35 ... Nc7?
Maybe check with the rook and try to get the rook over to the Kingside to stop the threats? |
|
| May-09-06 | | prinsallan: Cheesy Easy. |
|
| May-09-06 | | CAPA2422: I think g6 is better and I will tell you why.
When ever I am about to win a game. I try to lose as few men as possible.
If there is no need to sacrafice a Rook, then why do it? Who cares if it lasts a few more moves. If I can win with more material on the board, than that is what I will do. What has more value. 3 more moves? Or the rook who helped you the whole game. :o) The rook does.

| May-09-06 | | lentil: <DoctorChess> perhaps we should revoke your Ph.D.!
37. ...Nc7 is NOT ??.
White threatened 38. Rh1+ Kg8 39. g6 and now ...Nc7 gets mated by a pair of Re8+s, while after 39. ...Kf8 white has 40. Rh8#. Another attempt to defend with 37...g6 fails to a pseudo-backrank mate after Re7+, Re8+ and R1e7#. Black was lost already. Nc7 was the best practical chance in (i presume) a time-scramble. and <CAPA> immediate mate trumps eventual mate every time, especially in a time scramble! |
|
| May-09-06 | | Summum Malum: :) neat little sacrifice.. |
|
| May-09-06 | | mr j: nice mate :)
Very happy I got it as yesterday I stumbled! |
|
| May-09-06 | | eaglewing: Regarding what move is better, I agree with <CAPA2422>, 38. g6 does not sacrifice something important and you are safe, if you have overlooked something. Here, maybe timecontrol on 40th move was the reason to play on but again I would prefer the non-sacrifice move, played immediately without a second of doubt "is it really correct". In addition, in case of a blitzing game, where a fastest way to mate may be needed, please check the endposition of the game and 40 Kg4 Re3 41. Rxe3 Nc7 42. Re7 Kg8 43. Rxc7 Kf8
So, 38. Rh8 is won but not a closed mating net! |
|
| May-09-06 | | filipecea: <CAPA2422> More pieces on the board? For the sake of Morphy!! And what about the beauty of such sacrifices? The Rook became the "most valuable piece" (MVP) of the game... |
|
| May-09-06 | | jmelton: <DoctorChess: 35... Nc7?? A horrible move that caused Black the game.> Uh, cost Black the game?
Actually, White had a solid positional advantage from about move 15 on, and Black was lost by around move 25. White missed an easier/earlier win, 27.Nxh6! Qxh6 28.Rh5. |
|
| May-09-06 | | Marco65: <eaglewing> I totally agree with you and <CAPA2422>. Your line is of course still a clear win for White, but this is not the point. I wonder how many kibitzers saw and calculated 40...Re3 after 38.Rh8+. I didn't. Such surprises happen very often after a sac because the opponent might be willing to give back material in any crazy way, and you have to see and calculate all of them to be 100% sure your sac is correct. 38.g6 wins and makes life easier. Tournaments are not beauty contests. |
|
| May-09-06 | | krippp: <g6> immediately is actually a faster way to mate than <Rh8+>. Ask your chess engine if you don't beleive me. |
|
| May-09-06 | | Richerby: <Marco65> You don't need to calculate 40... ♖e3 because, as long as White can get his rook to the 8th rank faster than Black can get his king to f8, White will checkmate. 40... ♖e3 41.♖xe3 costs both sides a move each so doesn't change anything. Following that with 41... ♘c7 42.♖e7 does likewise. Then, if the knight moves, 43.♖e8# and if 42... ♔g8 43.♖xc7 ♔f8, then the checkmate has disappeared but White is up a rook for a pawn. This kind of sacrifice doesn't require any great thought because the worst that can possibly happen is that Black sacs a rook back and White's up the exchange again. |
