 Subject: There are correct sacrifices and....
Message:
Hi folks. I enjoyed Craig’s thread on miniature games and so I thought it would be nice to have something similar, except this time people get to shamelessly show off some of their favourite games where a nice sacrifice or two paid off.
Normally I get the opportunity to give up a minor piece for some clear advantage, but this recent game got my heart thumping. The sacrifices begin on move 20. I think it would be interesting to not only share games, but see if anyone else can come up with surprise rebuttals to sacrifices.
Thanks.

The game you showed wasn't really a sacrifice because there was a immediate combination to regain the piece. We need some proper sacrifices

... nice combination tim_b! There are sacrifices that lead to some more or less immdiate gain, and those that are speculative: the gains are other than material. Even temporary sacrifices to gain material can be interesting or exciting owing, possibly, to the difficulty of finding the idea.
Here's a game from my early days in which the closing sacrifices look pretty good, but they weren't at all difficult to find...
White: A. McL. Black: I.A.D. Latvian Gambit Auckland University 1973.
1.e4 e5 2.Nf3 f5 3.exf5 e4 4.Qe2 d5 5.d4 Nf6
6.Ne5 Bxf5 7.Bg5 Nbd7 8.Nxd7 Qxd7 9.Bxf6 gxf6 10.f3 0-0-0
11.Nd2 Bh3 12.fxe4 Rhe8 13.0-0-0? Bg4 14.Qb5 c6 15.Qa4 Bxd1
Having won the exchange, Black ought to win fairly easily from here...
16.Kxd1 Qg4ch 17.Nf3 Qf4 18.Ke2 Qe3ch?!
Prolongs the game by 2 moves. The right move is played on move 20.
19.Kd1 Qc1ch 20.Ke2 Rxe4ch 21.Kf2 Qc3ch 22.Kg3 Rg8ch 23.Kh3...
b
Now comes the final combination:
23...Rh4ch 24.Kxh4 Qf4ch 25.Kh5 Qg4ch 26.Kxh6 Qg6 mate.
The whole sequence from move 17 was forced...
From a correspondence game of the same year, I found myself sacrificing the exchange in what I thought was sheer desperation. Turns out it was probably correct:
White: I.A.D. Black: G.K. CC 1973 Ruy Lopez/Marshall Attack
1.e4 e5 2.Nf3 Nc6 3.Bb5 ... I very rarely play the Lopez..
3...a6 4.Ba4 Nf6 5.0-0 Be7
6.Re1 b5 7.Bb3 0-0 8.c3 d5!?
The Marshall. I like it as Black, but now I have to defend against it...
9.exd5 Nxd5 10.Nxe5 Nxe5
11.Rxe5 c6 12.d4 Bd6 13.Re1 Qh4 14.g3 Qh3 15.Be3 Bg4
16.Qd3 Nxe3 17.Rxe3 c5 18.Bd5 Rad8
So far, so book. Fischer-Donner a few years before continued 19.Nd2 Bb8?! 20.Bg2 Qh6 21.d5 c4?! 22.Qd4 etc. My opponent here improves on Donner's play:
19.Bg2 Qh6 20.d5 f5!
21.Nd2 c4! 22.Qd4 f4! 23.Ree1 Bc7!
A better square than b8, for sure: heading for b6 of course.
24.Re7!
Having the next move in mind... Frankly, I thought Black had a superb game at this point...
24...Bb6
w
25.Rxg7ch! Qxg7 26.Qxb6 Qf6?!
During the game I thouht this was a mistake, but it's hard to find an improvement...
27.Qxf6 Rxf6 28.Ne4 Rff8 29.f3 Bc8 30.Rd1 Bb7
31.d6 Bxe4 32.fxe4 f3 33.Bh3 Rde8 34.Bf5 a5 35.Kf2 b4
36.g4 bxc3 37.bxc3 Rb8 38.Kxf3 ...
At this point, 13 months having elapsed, came the time for adjudication. White has a straightforward win (3 pawns, two central passers at that, for the exchange), so 1-0.
At the time I was quite proud of the sac on g7, but was surprised how quickly the tables were turned...
Cheers,
Ion

[ report abuse ] | The first of the games...
Message:
... in heinzkat's last posting I highly recommend: a hugely entertaining fighting game, with amazing sacrifices for attack. I must check out the other games...
I especially enjoy sacrifices in the endgame, where material considerations start to loom very large. The diagram position is from a game I played against a German traveller who happened to be visiting this part of the world a few years ago.
w
Sure, White had an extra bishop, but Black's two extra pawns and active position was beginning to make the win look problematical. It's too early to call this an endgame, but it seemed that a major readjustment of the material situation would improve White's chances:
1.Bxh7ch! Kxh7
...else White's last becomes a smash and grab raid...
2.Qxf7ch Kh6
... 2...Qg7 is no better after 3.Qh5ch Kg8 4.Rd6 etc.
3.Rd7 Rh8
4.Rd5!? ...
This will do, but 4.Rd3 g4 5.Rd5 is more accurate.
4... Qg7
5.Rd6ch Kh7
6.Qf5ch Kg8
7.Rg6 Rh7
8.Rxg7ch!? ...
Still good enough, but the g5-pawn was available gratis...
8...Rxg7
9.Qxc5 Rf8
Black could equally well have resigned, but hoped that maybe something could be achieved on the king-side with those advanced pawns.
w
10.Qxf8ch ...
Now this really is hard to call a sacrifice. This is one of those situations that you kind of see at a glance, without calculating specific moves: the heavy pieces are forced off and the BK finds itself stranded too far away to stop the a-pawn.
10...Kxf8 11.Rc8ch Kf7 12.Rc7ch Kf6 13.Rxg7 Kxg7 14.a4
Black played on few more moves but the game is already decided.

I also thought that 25.h4 was not a good move. But white is in a zugwang the queen is immobile and also both rooks have no job. for eaxample any other plausible move except pxp will be followed by Ba6 which will seal the whites bishops fate. At 30th move probably giving the exchange back would have prolonged the game but the two connected passed pawns after mass cancellation will be vital. (in the game I was worried about this because my endgame is not so good :) ) Thanks for the comments Ion and sf115

[ report abuse ] | Missed opportunities...
Message:
Haven't we all wanted at some time or other to have played a queen sacrifice? Something to brag about. I have given up a queen on move 7, but that was in exchange for scattered material that was worth at least a queen. I have found my way out of difficult situations by a timely exchange of queen for rook, pawn and minor piece: a trade, really. I did once in a correspondence game sac minor piece and follow it up with a double rook sacrifice (or it would have been, except that the enemy resigned on the first rook - I wish I still had the score for that game....). But queen sacrifice? Nada.
Then just a few years ago, opportunity knocked... and went away unanswered. I even saw the early part of the combination, but stopped calculating too soon.
Here's the position:
w
Black is threatening mate in 2, but White has a strong attack.
What I ought to have played was;
23.Qxf7ch! Kxf7 24.Rxe7ch Kg6 (or ...Kf8 25.Re8ch 26.Kf7 R1e7ch 27.Kg6 etc)
25.Rg7ch Kxf5 (My original calculation stopped here, failing to notice the real implication of White's next..)
26.g4ch! ... (Black has just one legal move!)
26...Qxg4ch 27. hxg4ch Kf4 28.Re4ch Kf6 29.Rf7! (Putting the screws in and winning the second rook)
29... Rxf2 (Only move to avoid mate)
30.Rxf6ch wins the second rook.
Failing to calculate far enough, I played 23.f3 and won in much more prosaic fashion...

Ion

[ report abuse ] | Queen Sac? Ok, this is a Fav of mine...
Message:
Here is the only one I can recall making at GK, right now. But I really enjoyed making it, and planning it as the reply if he should play Bxg4 sac, as he did. Thanks to my opponent for pushing on into that interesting sac, which was probably the only way to try to make headway vs my Kingside, to sac thusly at some point. And having done do, the position really does become very dangerous and critical for my king, and should at least provide him with enough material won back, if I try to play thru it conventionally after accepting his B-sac.
The think I really enjoy about this Queen sac is that i think a Computer would Never Ever Ever do such a thing as Sac a Queen to go into to lengthy, pawn down endgame...
which I judged to be a nearly forced win for me at the time. However, later I discovered he could have played 37.Bd3 for a better position than in the game, and perhaps put the outcome into doubt then. The way it goes however, with 37.e5 still leaves a won ending I believe, tho it can go into several very delicate varations, EG such as having to nursemaid in a single pawn to Queen without allowing it to be sac'd for. Or another of being left with N+B to mate with ... which I practiced on for a week to get up to speed again on those! But finally got there ...
I really like this thread ... well done everyone~!

I know it's not a very complicated combination, but I still feel good for finding it.
1. ... Nd4! gives two threats, one of them harder to see. A fork Nxc2 and a strong attack with Rf3. I think that the best move for white would've been 2. Qg5 but even that loses a pawn to 2. ... Qxh3+! (if 3. gxh then 3. ... Nf3+). However, my opponent played 2. Rc1 unaware of the combination that was to follow. 2. ... Rf3!!. Now it's too late to play 3. Qg5 due to 3. ... Rxh3+ 4. gxh (4. Kg1 Rh1#) Qxh3+ 5. Kg1 Nxf3#. Here white should've played 3. Qxf3 though even that move loses, just not so fast.
Tell me if there are any flaws.

... The sac looks more like a rook sac, rather than a queen sac... But you still had to see quite a long way to make an assessment about thwe ensuing endgame. Sacrifices for such long-term positional considerations are in my view at least as interesting as those motivated by quick temporal or material gains... ;-)

Speaking of missed opportunities and rook sacrifices, here's one I "saw" and failed to play owing to time-trouble. It was the 3rd round game in a Labour Weekend tournament October 1973. I had the White pieces:
w
Although I did win the game shortly after the time control, I regret not playing
37.Qxe6! Qxg1 38.Qxf5ch etc with a forced mate, which would have been a fitting conclusion to a hard-fought fighting game, e.g.: 38...Ke7 39.Qe5ch Kf8 40.Qd6ch Kf7 41.Qc7ch! (A hard move to find in time trouble!) 41...Kf8 42.Qd8ch Kf7 43.Nd6ch Ke6 44.Bf5 mate. The reason for 41.Qc7ch rather than 41.Qd7ch is found if Black advances the king instead of retreating: 41...Ke6 42.Qe5ch (the square is inaccessible from d7) 42....Kd7 (42...Kf7 43.Nd6ch and mate next) 43.Qd6ch Ke8 44.Nc7ch Kf7 45.Qe6ch Kf8 46.Qe8 mate. The queen and knight make a wonderfully articulated attacking force.
Of course, Black could decline the rook, but with just one pawn for the piece, one imagines he wouldn't have been able to live long...

I did miss it almost. When I came in my analyses to the position after blacks 33th move the first time, I did try the queen sacrifice immediately (looks natural with the king being so vulnerable), but initially thought that white had nothing (I naturally tried the immedate rookcheck). Only a few days later did I notice that Nf4 creates a mating net, out of which black can't free himself, except when he gives back the material with interest.
Ofcourse the game is for the rest not extremely interesting. g5 Was very weakening, but I did not make the best use of it. The pawn sacrifice was certainly wrong (I missed the intermediate Nf5) and the exchange sacrifice was obvious though not even that good. Still, I like this game more than some of the objectively better games I played. The queensacrifice remains the ultimate thing to do in a chessgame.

... A Capablanca King's Gambit at some time or other, a Breyer Gambit (3.Qf3) at that. Something of a positional gambit, in which the pawn is given up in order - and here I want you to follow me closely - in order to obtain a better endgame. The follow up is more positional than tactical. Though there's no absence of the latter, Black remains permanently tangled and cramped, however hard he fights... Capablanca at his finest!

Message:
... do you get a better ending by 3.Qf3? Ask Mr Breyer! ;-)
But seriously, broadly speaking the purpose of the gambit becomes to establish a Q-side pawn majority, with the kings, naturally, castled on the K-side. At least, so I have read somewhere. Possibly it is intended this early either to recover the f-pawn quickly (establishing thereby a central pawn majority), or to force black to overcommit to its defence. At the same time, a more restrained (restrained, forsooth!) development ensures that White's attack doesn't fizzle out too soon, as it does tend to do in the main lines.
Do I believe any of this? Dunno, really...

Ionadowman had the following comment to make about the above game:-
"A closer look seems to indicate that 36.Rc1 would probably have held the draw:
36.Rc1 Rxh4 37.Rxc4 Bb6 38.Rxc6 Bxf2 39.Rxh6 Rxh6. Now, ordinarily this ought to be straightforward: White gives up his 5 pawns for Black's 2 and draws the R B vs R ending. Here it's not quite so simple, owing to the cramped King position - he could find himself imprisoned and mated in the corner.
So: 40.Rd2 Be3 41.Re2 f4 42.Kh2 hoping to break out by 43.g4. However, with 36.Bd8, it seems possible you had a draw in this line as well. 36.Bd8 Rxh3ch 37.gxh3 Rxh3ch 38.Kg1 Qg6ch 39.Kf1 Rh1ch 40.Ke2 Qa6ch 41.Ke3! (instead of 41.Nd2) and after 41.Qe6ch 42.Kd3 and White looks to be wriggling clear. Instead,
41...Rh2 42.Qxh2 Bxh2 43.Rd7ch Ke8 44.Rd2 and White still seems to be in the game.
So in the second case the sacrifice was unsound.
Hope all this helps.
