GM Sharavdorj vs. IM Friedel from the 2006 FIDE Swiss at the East Bay Chess Club in Oakland, CA.

It is White to move. Do you know how to draw this type of position as Black?

Hello Susan?

Do you give the answers of this type of questions in your blog? When we can’t find the solution we would learn from your explanations. If you give the solution for example one day after here in comments it would teach us a lot.

Thanks a lot,

happy holidays,

Montrealer

keep king and rook on white and try to trade rooks when the black rook is on the same rank or file as the King?????

Montrealer, I would give the answer if no one solves it correctly. The good thing is someone always give a correct answer for the puzzles. You just have to work and see which is the correct one?

Best wishes,

I have no idea. Endgames are by far the weakest portion of my game.

Time to start studying….

(Or maybe order one of Susan’s new videos…. ðŸ™‚ )

Keep your King in the center.

And your rook close to it.

Thats my recepie.

Michael, please explain your theory about white squares. I’ll only say: Avoid black corners if you get squared in this endgame. And don’t let your opponent sing Elvis Presleys “Your so Squared” !

If you are black, keep your rook on the third rank, dividing Black and White kings and preventing White King to come close. No?

ok basically the drawing idea if i remember correctly is to keep the rook away from the center and check from a distance (vertically behind the strong side king

)….and when the white king decides to go to one side of the board you go to the other.

the defending rook will stay on d or e file and thus cut the strong king off from one half of the board and when the bishop gets behind the king to allow it access to the other side of the board you simply move your rook up one rank keeping the pin and this keeps the enemy king from approaching the sixth rank to deliver mate.

i did a database search and Flohr-Reshevsky 1937 is a good example of this.

John Nunn’s excellent and highly readable ‘Secrets of Pawnless Endings’ give a review of KRBKR, Chapter 7. He says that the endgame is theoretically a ‘general draw’ but that many defences otb drift into marginal positions which they lose.

In section 7.1, he cites two drawing approaches, the ‘Cochrane Defence’ and the less well-known, analysed and played ‘Second Rank Defence’. Neither seem imminently needed in this drawn position. The attacker’s problem is that it cannot swap off Rooks.

Only 2 of 74 otb examples reviewed by JN were lost in theory: many more were lost in practice. This is an example of why the ‘awarded draw’ rule in the Kramnik-FRITZ match was a major concession to the human player.

So in summary, my advice on drawing this position is to buy Nunn’s book (either edition) and read it more thoroughly than I have ðŸ™‚

It is a draw but not easy as top GM’s have lost. However mostly it is a draw if you know already what to do.

Black has Black squared bishop in example given.

1.You need to defend for 50 moves so do not forget to claim draw when time arrives!

2.Be careful with time management. Any ending can be lost in a time scramble.

3.Keep the King in the centre of as long as possible.

4.Be aware of gaining moves by opposing rooks, pining Bishop etc but do NOT play for checks if it just helps attacker move forwards and puts your king in a box.

5. Possibly you will be forced to go to an edge of board at some point so do not panic.

6.When King goes to edge-lets say the a-file (say a6). The rook should be on b file (say b3) i.e. 2nd rank.

7.Notice that rook (b3) opposite colour from Bishop so no discoveries.Also notice King moved towards white corner so if King can go to b7 without being boxed by Bishop.

8. King can then go to b5+b4 or if Black rook goes to b8 King can go to b7. There is simply no forced mating pattern that works here .

9.There is a stalemate motif that if Kings in opossition one file apart the defender (rook already on 2nd rank) plays rook with check -if bishop takes then stalemate.

stay off of black squares — and exchange rooks — and use 50 move rule

i’ll give you my “line of horror” or – HOW NOT TO PLAY THIS ENDGAME on the weaker side – in PGN

(i did a similar analysis a few years ago – with the help of fritz 2 or so – and i’ve tried to adopt it for the given position and translate the comments and notation to english – hopefully there aren’t too much transposing errors and the file will work!?)

have fun ^^ – and find stronger moves than me and fritz one or two (i do not remember exactly). ðŸ˜‰

Hello Susan,

These puzzles and posts are really useful.

However, there are so many different viewpoints here it is hard to understand which is the correct strategy. Maybe they all are ðŸ˜‰

So it would be useful to have a summary of the correct strategy.

THanks and happy holidays!

Dear Susan,

I have a little understanding about this type of remaining pieces in the end but my idea (pls correct me if im wrong..)is to put your king into the corner together with the rook and the corner you need to choose is the color opposite to your opponents bishop?im not so sure..nevertheless this is my own little way of sharing my not so deep ideas..thanks..

I remember computer analysis in the 1980’s (?) showed R+B vs. R is sometimes winnable except the win can take over 70 moves. FIDE changed the 50 move rule in the 1980’s or 1990’s to allow up to 100 moves or something in this type of position. It drove players crazy. Then it got worse, R+B vs N+N turns out to be a win needing over 200 moves. No players would possibly want to grind out such an ending. FIDE gave up and went back to the strict 50 move rule regardless of material on the board after that, I think.
