THis is an example from GK's Book : Kasparov teaches chess .

If you can first read this book page 114 .

In your opinion what is the result ? and variasion .

Note that Black is to move .

Avatar of khpa21

Black is simply losing. There is no way to hold the e-pawn, and Black doesn't have the fortress set up so he can't maintain that either

EDIT: I forgot that Black can move the king. Rethinking evaluation...

Avatar of khpa21

1...Ka3 2. Qc5+ forces a perpetual check. The position is drawn.

Avatar of Eebster

1... Ka4! also draws.

Avatar of Behroozfar

Most of all say that this is a draw
But Kasparov has another opinion ! he says that white wins .
He says that by stalemating the black king , black's pawns will fall .

well , what do you think ? any idea about this

I don't doubt that Kasparov's opinion is right, but I'm not sure how White goes about stalemating Black's king

Well, Nalimov definitely gives a draw, after either Ka4 and Ka3

yes but white can win...


No, he can't. Sorry, if I have to choose between believing Kasparov or the Nalimov tablebase, I'll choose the tablebase everytime.

Put the position in here: http://www.k4it.de/index.php?topic=egtb&lang=en

and see for yourself

Well
I put variasion that Kasparov gave it .
but i should mention that kasparov said Khenkin found this variasion .

" Winning the pawn . now white's king moves to d2 , winning the d-pawn in the same way ."
is there anyone that can improve black's play ? plaese .

2... Ka5? does indeed lose (in 43). 2... Ka5? 3. Kd1! Rc3 (3... Kb6 4. Kb5 Ka6 5. Kc1 Rc3+ 6. Kd2 Re3 7. Qc5 Qb7 8. Qd6 Kc8 9. Qe7 e4 10. Qa7 Rd3 11. Kc2 Rc3 12. Kb2 Rc6 (12... Rd3 13. Qa8+) 13. Qxd4 wins.) 4. Qd5 Kb4 5. Qxe5 wins.

2... Ka3! can hold, but leads to the same line you gave above for a while. For example:

1. Ka4 (or 1. Ka3) 2. Qc4 Ka3! 3. Qb5 Ka2 4. Qb4 Ka1 5. Kc1 Rc3+ 6. Kd1

but then 6... Re3! draws. It is hard to prove why, but the tablebase says so.

Please Make a diagram  to play moves there .

Avatar of Eebster

It appears I made some typoes in a sideline. Here is the corrected version:

Of course, I don't know how to prove that the position after 6... Re3! is drawn.  If you want to give some try lines I could show you the refutations but it would be easier for you to test it out yourself. In my opinion, the best site for the complete Nalimov 6 man tablebase online is http://www.shredderchess.com/online-chess/online-databases/endgame-database.html. I use it all the time.

When i posted this topic i thought that black easily get the draw with 1.... Re3 , sacrifice one pawn and make a fortress with other pawn and helping from king . but i see that i was wrong and black cant get draw with that ( you can try this ) . but has another drawing line ! thank you dears .

 If everyone visit Kasparov anywhere please tell him to correcting this in his book !

I got what i was wanted of this topic and see that (( not Kasparov and not me but nalimov tablebase )) !
