Pat: Why do I think there's another "but" coming up?

Noah: You're right. "But" he spends a tempo on pushing his own f- ! and that costs a tempo.

White uses the tempo to break the a5-blockade and tie up the black t=! -not the

�-on the a-file.

Pat: And that means what?

Noah: That means a mismatch on the �-side where Black's lone W is trying to fight two mobile pieces without the benefit of his t=! .

Pat: Black is even in danger of lOSing in Diagram 141.

Noah: Deservedly. He com­

mited the sin of taking too long to use his W-and in an endgame that's often a mor­

tal sin.

Pat: Seems like there are al­

ways mismatches in + ! endgames.

Noah: Naturally. One of the most common themes is shown in Diagram 142.

White's b-t , with the sup­

port of � and 11, must win a

� on the * .. side. Black's � is no match for three enemy units.

Pat: But if he'd played accu­

rately?

Noah: Then there would be a balancing mismatch on the W-side. Black's <if? would cre­

ate at least one passed t that would eventually cost White his � .

But he lost a vital tempo-in fact, he lost three tempi-with his faulty � -move.

Knowing when to reposi­

tion your � -from in front of a t to the side of it or behind it-is one of the most subtle skills in rookdom.

Diagram 143 is a fine illus­

tration.

Wd3 Wd5.

Pat: Looks drawish to me since

�xg7 can't be stopped.

Noah: True, but Black can re­

position his � just in time.

Pat: Behind the a-i ?

Noah: Ideally, yes. But it can go to c5 if needed, as in the 3.

� as line in order to free the t; so it can chase the white � from its best square, as.

Pat: So both �s get shifted, Black's during moves 1-4 and White's during 6-S. And White gets back just in time.

Noah: But the difference in

� s in Diagram 144 is termi­

nal. White' s � is almost out of moves and space, and he can only pass with his t;.

It's entirely appropriate that Black finishes off with another repositioning of the � -from the a-file to the third rank.

Pat: So sometimes the � is the star of the endgame and some­

times the t; is.

Noah: But ideally they should coordinate-as they do after

13 .. . � d3! in this case.

"Always put the Rook behind the pawn • • . Except when it is incorrect to do so. "

-Siegbert Tarrasch

Pat: So when doesn't the � belong behind the t ?

Noah: When it can be more useful on a rank, as in Dia­

gram 145. White spoiled his chance to advance in the world championship

elimina-tions by following the old cliche.

Pat: I don't get it. What can possibly be wrong with 1.

�al?

Noah: The a becomes a pas­

sive bystander on al once Black blockades on as.

But on e4 it would have kept the e- t under attack, creating the possibility of a

<&>+ t vs. a mismatch on the 'l!J-side.

Pat: I guess a � isn't that much stronger than a <&>.

Noah: As I mentioned earlier, when we were talking about mismatches, usually a � can­

not stop a tJ from advancing a nearby t . But there's a big exception.

Pat: Let me guess. It happened in Diagram 146.

that because he has the

"checking distance."

Pat: What's that?

Noah: It's a device that en­

ables a � to prevent a �­

supported t from advancing by checking the � from in front of the t .

If the enemy t is no further than the fourth rank, as it is here, there's plenty of room in front of it for a � to check and keep the enemy � from

supporting the t 's advance.

Bear in mind the checking distance only applies to a � in front, not in back as in 1 . . .

� dl.

Pat: The problem for me is that all these positions look alike.

Noah: Same for most of us.

Even the great authorities on the endgame get mixed up, as in Diagram 147.

Pat: Who played this?

"The simplest Rook­

endgames contain a lot oJ surprising little

secrets. "

-Mikhail Botvinnik

Noah: No one. It's a study by a famous composer named Nikolai Grigoriev.

He showed that White can win-even though Black has

"the distance" -by cleverly seizing the a-file for his W's approach.

Pat: So?

Noah: What he missed is the main distinguishing feature of the position: That Black's W is cut off by rank, not just by file. So 1. � h5 wins much faster.

Pat: So much for the great Grigoriev.

Noah: Worse than that. The same study was used in the most respected book on the subject, RookEndings, by Lev­

enfish and Smyslov-with no mention of 1. � h5.

But 1. !! h5! makes 2. b5! un­

Even 2. !! c5 and 3. !! h5 wins faster than the book line.

Otherwise 4. Wxa4 wins as in

is. moves that work in every t!

ending?

Noah: I'm afraid not. Chess isn't a multiple choice test.

White's task in Diagram 148, for instance, is quite hard­

even though he not only has an extra t but has the better placed t! .

Pat: But doesn't Black's t! get in the way on the g-file?

Noah: Yes, and thanks to his accurate first two moves, the long-distance white t! is able to make a crucial transfer.

Pat: Where?

Noah: At move 7. The t! can­

not get to g8 where it would

slow the march of the enemy t . So it goes to d3 where it cuts off the black � from the

�-side and still slows the g­

t .

Pat: And that's it?

Noah: No, there's one more subtlety at move 9. But there it's just another case of keep­

ing the t! more active than Black's.

Pat: I'm getting confused by where or when the t! be­

longs.

Noah: No surprise. The role of the t:! may constantly change in the course of an ending.

In Diagram 150 Black cor­

rectly places his t:! on d5, where it cuts off the white � from the -(t-side and tries to immobilize the enemy t:! by tying it to the defense of the c5- i .

Pat: So White trades is.

Noah: And makes a fine trans­

fer with 4. t:! a3. The t:! can W-side singlehanded against Black's only source of coun­

terplay-an attack by his <it and is.

Pat: What is Black's t:! doing in the meanwhile?

Noah: It was correctly used to prevent the W and i (S ...

t:! as!) from advancing.

Pat: But it looks like he missed something later.

Noah: Something big. In Dia­

gram 151 he could have pen­

etrated along the d-file-an active plan. Instead, he kept his t:! flexible-yet passive-on as. This allowed White to use his � and t:! to advance the i to the fifth rank.

Pat: And Black's only chance was to find an entry on the �-side for his W to gobble is.

Noah: A good plan but easily stopped by White. It may seem like magic that White makes progress in moves 16-21 and Black doesn't. 3. �e2 and White makes progress).

"Good is

-Vasser Seirawan

Once White had tactically killed off all counterplay his opponent threw in the towel.

Pat: Does the defender have to be just as flexible?

Noah: Sure. He usually has even more useful things he can do with his t! than the player with the advantage.

Pat: I don't see that at all.

Noah: Try Diagram 153 on for size. You tell me what should happen.

Pat: Okay. First Black tries-to and two connected is against a mere �.

Pat: But White crosses him up with 3. � b6t, which cripples both the � and i .

Noah: And what else does that do?

Pat: It forces Black to use his

� to break the b6-blockade.

Noah: Right again. Once the blockade is broken the W can return to the W-side.

Pat: Then White can win if he cuts off the black � with his

� .

Noah: But notice how differ­

ently Black uses his � . At

move 10 it swings back to provide a bridge for the � to

fl.

As usual the defender' s � is best stationed in front of the enemy is. And that frees the black � for one last duty.

Pat: I see. The checks along the b-file. White can't take his own � away from the first rank or Black queens.

Noah: And if and when he removes his � far from checks, Black attacks the �­

side pawns with his � , creat­

ing a final mismatch.

Pat: Aren't there any kind of general rules that you can learn instead of trying to re­

member all these key posi­

tions?

Noah: Hmmm. There is one mildly useful rule for � + i

endgames. But almost no one west of Kiev and south of a 2400 rating knows it: the Rule of Five.
