"Draw claimed; draw agreed" says my score sheet. Thereby hangs a tale: I was the last board to finish, with two minutes to his one, and White decided I was trying to win a drawn position just on time, and claimed a draw.
I was indeed trying to win, and the clock may have helped, but White has lots of ways to lose: his last move was actually the last chance to draw!
Quite exactly why we'll see in a bit, but on the day a bit of discussion broke out amongst the audience (yertis notisnt yertis notisnt...) and we decided we'd had enough.
It's certainly true that some very similar positions are drawn, and are maybe even claimable under the "two minute" rule, but not this one! The interesting thing is, nobody there knew it well enough to carry the day, and I've had positions like this lots of times. If my opponent knew how to draw it he would never have played Re1; Capablanca won two positions similar to this where his opponent did not know the drawing technique in one year, 1931 (one against Turover). Moral: know your onions!
Another thing that decided me on having another crack at a session on Rook endings is, well, a bit of a tease:
"...the number of positions that must be known exactly is relatively small. It is only in Rook endgames that it is essential to memorise thirty or forty concrete positions; in other types of endgame there are even fewer."
Mark Dvoretsky in Dvoretsky & Yusupov, Technique for the Tournament Player
Forty sounds quite a few to me, but, OK Mark, which forty? He doesn't say! I still don't know, really, but here is my suggestion for some of them.
One way to work your way into this is to get a chessboard and a few pieces and see if you can work out some of the basic rules for yourself. You should quickly discover that, in common with many other endings, two passed Pawns pretty well always win, and so situations with a single Pawn are most critical. Also, if both Kings are distant, one Rook can't force through a Pawn against another Rook (not like Queens, for instance).
So, we quickly get to our first two critical positions out of Dvoretsky's forty, where the Kings are in range: Lucena's position and Philidor's position. Oh, and you need to know about Rook's Pawns, and checking distance.
White has control of the sixth/seventh with the King and the Black King is cut off: Lucena's position is won for White is two ways...
First, White can get the Pawn to the seventh:
1...Kc7 2.Rc2+ Kb6 3.e6 Rd1 4.Ke8 Rg1 5.e7 Rf1
6.Rc4 the critical manoeuvre: 'BUILDING A BRIDGE'
[6.Rh2 although the 'bridge' manoeuvre is always emphasised in the books, there is also a win by getting the king out on the short side, e.g. 6...Kc7 7.Rh7 Rf2 8.Rf7 Rh2 9.Rf8 Rh7 (9...Re2 10.Kf7) 10.Rf1 Rh8+ 11.Kf7 Rh7+ 12.Kf8 Rh8+ 13.Kg7 Re8 14.Kf7 This is important because the bridge-building manoeuvre may not be available]
6...Rf2 7.Kd7 Rd2+ 8.Ke6 Re2+ 9.Kd6 Re3 10.Rb4+ Ka7 [10...Ka5 11.Rb8] 11.Rb5 Rd3+ 12.Ke6 Re3+ 13.Re5 1-0
Black's King holds the Queening square, and the Black Rook holds the sixth rank. This is Philidor's position, which is drawn without too much trouble by Black.
Once the White Pawn goes to the sixth, Black runs back to the first rank:
1.Kf5 Rb1 2.e6 now there is no shelter on the board from the checks
[2.Ke6 Rb6+ 3.Kd5 Rb1]
2...Rf1+ 3.Ke5 Re1+ 4.Kd6 Rd1+ 5.Kc6 Re1 1/2-1/2
Rook's Pawns are a strong drawing factor.
So, here, even with the Black King distant, White can force nothing.
Oddly, Black must not try to approach with the King because of Ra8-h8; instead the Black King sticks to g7/h7, and the Rook checks the White King when it approaches.
1.Kf3 Ra4 2.Ke3 Kh7 3.Kd3 Kg7 4.Kc3 Kh7 5.Kb3 Ra1 6.Kb4 Kg7 7.Kc5 Rc1+ 8.Kb6 Rb1+ 9.Kc6 Ra1 10.Kb7 Rb1+ 11.Kc7 Ra1 1/2-1/2
If the White King is closer than the marked area, White wins: in the marked area, Black should draw.
Even further back, and we're into a lot of ifs and buts...
You can draw without getting Philidor's position, by checking along the ranks. With a central Pawn this is just possible as long as you take the furthest possible file: here the a-file.
1...Ra8+ 2.Kd7 Ra7+ 3.Kd6 Ra6+ 4.Kd5 Ra5+ 5.Kc6 Ra6+ 6.Kb7 Re6 1/2-1/2
Checking distance is three empty files.
The b-file (two empty files) fails by a whisker:
1...Rb8+ 2.Kd7 Rb7+ 3.Kd6 Rb8 4.Kc7 Ra8 5.Ra1! 1-0
It is popularly supposed that Q vs. R is difficult: it surely is difficult against an opponent who plays perfectly, like a computer (as GM Browne once discovered), but in actual play it may be easier. Black can be herded to the edge, when a Rook on the third (sixth) rank must keep out the White King. You can achieve positions like the following:
The Black Rook is shut out from the third rank, and is vulnerable to forks:
[1...Rh1 2.Qc8+ Kf7 3.Qb7+;
And if 1...Rh8 2.Kg6 Rg8+ 3.Kf6 1-0
Here is an instructive study: Black to move.
A tense position: on whose side will it resolve? 5-piece Rook endings (KRP/KR) all hinge around access of the sixth and seventh ranks in front of the P by the attacking King - if it can be kept out, the defence holds, but if not...
[1...Rh6+ 2.e6 +-;
1...Rd1+ 2.Ke6 Kf8 (2...Kd8 3.Ra8+ Kc7 4.Ke7 Rh1 5.e6) 3.Ra8+ Kg7 4.Ke7 Rd2 5.e6 +-;
1...Rh2 2.Ra8+ Kf7 3.e6+ Kf6 4.Rf8+ Kg7 5.e7 +-]
Critical - on the other side the Black King gets in the way of checks from the Black Rook, and the White King can make a little shelter for itself behind the Pawn. When the defending king 'takes the short side' there is no refuge for the White King.
3.Ra8+ Kg7 4.Re8 [4.Kd6 Kf7 =] 4...Ra1 5.Rd8
[5.Kd7 Ra7+ 6.Kc6 Ra6+ 7.Kb7 Ra1 =]
5...Re1 6.Re8 Ra1 = the White K is in, but has no escape from the checks! 1/2-1/2 Remember this type of draw, we'll be meeting it later.
Now, back in Liskeard, how do we compare? We can see that compared to the last few drawing ideas White is badly placed: the defending Rook is passive (no harassing checks) and the King threatened with mate. White must run for the short side with the King, and send the Rook away to draw:
[63.Kg1! f4 64.Re8 (64.Ra6) 64...Rb1+ 65.Kh2 Kf2 66.Ra8 f3 67.Ra2+ Ke1 68.Kg3;
Instead 63.Re1? f4! wins for Black:
A) 64.Kg1 Kg3 65.Rc1 (65.Kf1 Rh2 66.Re8 Rh1+ 67.Ke2 f3+ 68.Kd3 Rd1+ 69.Kc2 f2) 65...f3 66.Ra1 Rh2 67. Kg1 f2+;
B) 64.Ra1 64...Kg3 B1) 65.Kg1 f3 66.Rc1 (66.Kf1 Rh2) 66...Rg2+ 67.Kf1 Rh2; B2) 65.Ra8 65...Rb1+ 66.Ke2 f3+ 67.Ke3 Re1+ 68.Kd2 f2;
[63.Ke1? on the long side is an obvious no-no: 63...f4 64.Re8 Rb1+ 65.Kd2 Kf2 66.Rf8 f3 67.Kd3 Kf1 68.Ke3 Rb3+ 69.Kd2 f2 70.Rg8 Rb5]
For other positions it really depends who can get their King in first, or at all; if the side with the Pawn can keep out the defending King they can win. John Nunn has written a whole book about positions with just one Pawn on the board, so you will forgive me, I hope, if I say they are sometimes tricky. We have seen a hint of this when we looked at Rook's Pawns above. There is, however, a guiding principle:
If the sum of the number of the rank on which the Pawn stands and the number of files that separate the Black King from the Pawn is five or less, then it's a draw; greater than five, it's a win. (Dvoretsky)
Here the Black King is cut off by three files = 3
The Pawn is on the third rank = 3
The sum is = 6
6 > 5, so it should be a win. But how? White keeps out the Black King and advances the Pawn; Black defends with harassing checks, this time from the front. The White Rook would be even better placed on f7, cutting the Black King off from the last rank and ready to intervene on the other side.
1... Rb2+ 2.Ka7 Rc2 3.Rh5+ Ka4 4.Kb6 Rb2+ 5.Ka6 Rc2 6.Rh4+ got the idea? we've gained another rank 6...Ka3 7.Kb6 Rb2+ 8.Ka5 Rc2 9.Rh3+ Ka2
10.Rxh2 ! 10...Rxh2 11.c8Q 1-0
This is an important blockade: White, oddly, can do nothing.
1...Ra5 the a-pawn is nearly there, but with a distant White King everything can (just) be held
With the Pawns further back we have another realm of headaches: White is generally better placed to manoeuvre and Black less well.
This is quite different - with the other White Pawn further away from the short side there is a skewer opportunity. once you know you can steer for this one you can win from more complex positions 1.f6+ Kf7 2.Rh8 Rxa7 3.Rh7+ 1-0
(1) break the blockade
(2) win the f-pawn
(3) win as we know how
1...Kh7 2.Kc1 Kg7 3.Kb1 Ra3 4.Kb2 Ra4 5.Kb3 Ra1 6.Kb4 Ra2 7.Kb5 Ra1 8.Kc6 Ra5 9.Kd6 Kh7 10.Ke7 Ra6 11.Kf7 Ra4 12.Ke6
this is the critical bit: zugzwang!
12...Ra5 13.Kf6 Ra1 14.Kxf5
nearly there now
14...Ra5+ 15.Ke4 Ra4+ 16.Kd3 Ra3+ 17.Kc2 Ra2+ 18.Kb3 Ra1 19.f5 1-0
A relevant position has arisen. In the event Black won quickly:
53.Kh3? f4 54.Kh4 fxg3 55.Ra6+ Kf5 56.Rf6+ Ke4 57.Kh3 Rf3 58.Ra6 Rf5 0-1
53...a4 54.Kg2 Ra1 55.Kf3 a3 56.Kg2
(56.Kf4 a2 57.Kf3 Rf1+)
56...a2 57.Kh2 Kxg5 58.Kg2 Kf6 !
(58...f4? only draws)
59.Ra5 Ke6 60.Kh2 f4 61.gxf4 f5
which we should know how to win.
(58...f4? 59.gxf4+ Kg4 60.f5 f6 61.Ra5
no zugzwang is now possible with the White Pawn on the 5th)
My faithful analyst Fritz successfully embarked on:
62.Kg2 Kd6 63.Kh2 Kc6 64.Kg2 Kb6 65.Ra8 Kc5 66.Ra4 Kb5 67.Ra8 Kc4 68.Kh2 Kd4 69.Ra4+ Kd3 70.Kg2 Ke3 71.Kh2 Kf3 72.Ra8 Kxf4

"There comes a point when you have to stop making your moves by common sense, and instead, after analysing a concrete path to a draw, you must force events." - AY
51...Kc7! 52.Rxg7+ Kb6 53.Rg6+ Ka7 54.Rc6
54...Rxf2 55.Rxc5 Rxf4
[55...Kxa6 may be better, except that Black would have to keep thinking carefully how to draw with time running out.]
"Black has absolutely no need for this Pawn, then try not to be distracted by non-essential details (like, a 'non-essential' Pawn)" - AY
Artur has confidence because he has studied this position. GM Gurevich actually managed to lose one of these in the US Championship in 1989 (and I don't think he was the first). Miles wrote it up in NIC, commenting: "This ending is of course drawn, but the defence is not easy". Dvoretsky interjects: "No, it is very easy" - if you know what to do!
60.Kxf3 Rc5 61.Rh8
(adjourned: the game could be given up here but Karpov saw no reason not to test Yusupov's technique.)
White will attack the side away from the defending King with his own King. Black cannot touch the Pawn with the King here, but will keep the Rook away from the opposing King for checking distance: here the c-file is best so it can check from the seventh rank.
The White Rook is passively placed which is the downfall of his winning hopes. Black draws just as he would without the a-Pawn on the board.
(N.B. With the White Rook active and the Black Rook passive White can and should win by getting the King in.)
61...Rg5 62.Ke4 Rc5 63.Kf4 Rc4+ 64.Ke5 Rc5+ 65.Ke6 Rg5 66.Kf7 Rc5!
[66...Rd5? lacks checking distance and loses 67.h6 Rd6 68.h7 Rd7+ 69.Ke6]
[67.h6 Rc7+! (67...Rh5? 68.Kg7) 68.Kf6 Rc6+]
67...Kxa6 68.h6 Rc7+ 1/2-1/2
This is the game that made this type of ending notorious; not the first time that it had occurred, but Rubinstein, such a master of endings and particularly Rook endings, may have fancied his chances here...
51.Kb3 Rb4+ 52.Kc3 Kb5 53.Rb8+ Ka4 54.Rc8 Rb3+ 55.Kc2 Rb5 56.Rh8 Kb4 57.Rh1 a4 58.Kb2 a3+ 59.Ka2 Ka4 60.Rc1 Ra5 61.Rb1 c4 62.Rb8 Rc5 63.Ra8+ Kb4 64.Rxa3 c3 65.Rb3+ Kc4 66.Rb8
You can win these positions, by working your pieces right in and trying to achieve "Lucena" without allowing the "short side draw". This cannot be forced. Black should resist the advance, get the King to the King's-side and only once the Pawns are advanced send the Rook away to a1.
60...Kf5 61.Rg4 Rh8+ 62.Kg3 Ra8 63.h4 Ra1
Right square, wrong moment. White gets the Rook active behind the h-Pawn and threatens to run it with the King cut off.
64.h5 Ra6 65.Rh4 Rh6 66.Rf4+ Kg5 67.Rg4+ Kf5 68.Kh4 Rh8 69.Rg5+ Kf6 70.Kg4 Kf7 71.Rf5+ Kg7 72.Kg5 Rg8 73.Rf6 Kh7+
Well, the King has made it to h7 but the Black Rook now need to be on the far rank (a1-h1). White whips the King in to win.

Black appears to have better Rooks, but the Q-side pawns are advanced and vulnerable. This vulnerability costs Black the a-file, and that costs him the activity of his Rooks. 22.Rd4 Rf6 23.b3 cxb3+ 24.axb3 Kf7 25.Kd3 Re7 26.Ra1 Ke6 27.Ra6 Rc7 28.Rda4 g5 29.h4 g4 30.Ke2 gxf3+ 31.Kxf3 Rff7 32.Ke2 Kd6 33.b4 Rb7 34.h5
