No I give up. I have to know more about the problems. It's not a forgiving viewer.

Thanks for trying 🙂

oh my god, yes I did that by mistake, while trying to find out what the hell was wrong with mine! sorry for stealing your hard work 🙂

I'm not sure but I think you made a mistake on the Rook to c4 move, it only said "c4" instead of "Rc4"

Now what was it you wanted to say

(cleans the sweat on the forehead, gathers his breath). Well, I was just trying to make a point about the rook sacrifice of aronian being called a "petrosian sacrifice", by pointing out it's resemblance with another sacrifice Kasparov describes as such.

By the way, I just copied and pasted the game from chessbase. then I tried to do what wormwood suggested (clean the spaces on the beginnings and the ends), then I tried to clean all spaces between the move number and the white move, then everything faded into a blur and I don't remember the rest.

Kramnik can perform this trick too...

Yep, there's your petrosian sacrifice! (as I know it 🙂 )

you only need to clean up the linebreaks, and only in the algebraic notation part. the rhp viewer doesn't see them as whitespace. that's the the problem 99% of the time. but apparently you had something else.

Hi PP.
Good Thread.

I've picked up something about the 'Petrosian sac' and you have learned
how to post a PGN. 🙂

Well if the big K is calling any exchange sac the Petrosian sac
then I won't make an issue out of it.

What differs is my terminology of a sacrifice.

Leaving a Rook or placing a Rook where it can be taken by a minor piece
is a passive sac.
(the guy does not have to take it )

Picking up and Rook and taking a Knight (or Bishop) is an active sacrifice.
(the guy has no choice, take it).

And as I think active sac most of time then RxN is an exchange sac.

Mind you thinking about it there was the Petrosian - Spassky world title match.

Petrosian played a wonderful double exchange sac both N + B.
One passive and one active.

Here. Black has just played Bh3 and Petrosian leaves the Rook on f1.
A few moves later he plays RxN. A brilliant and fitting example.

It's only 10 moves, spin it out, the end is yummy. A bit like the trick
ccnoob missed in his Play Like a Grandmother thread.

(Perhaps the real 'Petrosian sac' should have two exchange sacs in it) 😉

Hi PP.

Got a real cheapo for you and by fantastic coincidence it has
an exchange sac in it. A RxN look out for move 33.

His return sac 34.Rc3 is the only move.
Sometimes they work - other days they don't.

Turned out to be a good thread this. I'm White.

Well't that's a very relevant post then, a cheapo with a rook sacrifice 🙂

And ouch, it's too bad Bxe6 at the end was also hitting on the rook. I was getting excited 🙂

Thanks for the games.

I also did a google on the subject, and it seems the "original" petrosian sac is this one against Reshevsky.

I mean, come on, it's like a joke. The guy just hangs his rook 😀



Really, this reminds me of how far, far away these people are.

By the way, this features a return sac too, maybe you were right about having 2 sacs being the trademark of a petrosian sac. 🙂

note to self:
When have you become such a smiley person, philidor? What is going on here?

A few years ago the "Topalov sac" was really hot, RxN somewhere and then, due to the greater strength of a knight in the middle game - the opponent's rooks were static - he screwed his opponents big time.

Well it's not easy for the term "topalov sac" to be RxN specific as the guy can sac anything all over the place.

I remember GM Larry Kaufmann (Rybka's ex-"coach" ) talking about this sac as one of the best novelties in history. It really doesn't get any better than this. I vaguely remember his novelty check-list:

-occasion: check (wijk an zee, classical time control, high level tournament)
-players: a huge check. Two elite players, who battled in the latest WC match at that point who also happen to dislike each other a lot.
-the move itself: another solid check. a complete piece sacrifice which although not objectively sound, has created great practical chances. and it's a pretty early novelty (12) for a semi slav at that level.



note from author: this doesn't change the fact that topalov is a sore loser and kramnik is the best. 🙂

The best part of that was that Timman tried the same against Ljubojevic the next day... and lost.
