I think fatty is sunk.:hmmm:

30. Rg1xg7

Theory knows that KRPP vs KR still can end as a draw, but only with pawns in three possible combinations of lines on which they must travel, or in case of double pawns. Mostly, this endgame is a win for the superior side. KRPP vs KRP also can end as a win or draw. But I think I defend at least a two-pawn-lead.

Don't lose a third one, Fatty, that would seal it. ;)

31. Kd3xd4

Kd2 seems to work, too, but the only way is forward!:yeah:

A win is unlikely, but then, he still needs to checkmate.

To crush your enemies...!

Thank you for taking the theoretically wrong pawn. ;) That rules out the critical combination of pawns on a- and h-line, which in KRPP-KR would give Black a fair chance to hold a draw (beside pawns on a- and c-line or pawns on f- and h-line). :salute:

You're welcome? :doh:

33. Ra7-b7

That should be a more pressing end game than the prototypic 33.Ke4/Rxb2 34.Kf4: At least I hope.

End game theory. It is known that in a situation KRPP versus KR, the inferior side can often enforce a draw in case of the pawns on a- and c- line, or f- and h-line, or a- and h-line, if the inferior player can manage to work towards positonal key elements, that is to get his king in front of the a- or h-pawn. These constellations of pawns on the critical lines are no longer possible, and that is good for me and bad for you. :

Consider this explanation a strike by psychological warfare. :D

But it will still need plenty of moves before I can enforce a new Queen.

You will have to shoot me a link or something with a better explanation after we're done.

Any comprehensive book on end game theory.

I have the four-volumes edition of André Chéron's classic endgame encyclopedia (not that I know all that inside out, please save me...).

http://en.wikipedia.org/wiki/Andr%C3%A9_Ch%C3%A9ron

It was a standard work and a revolution by the time it was published (the 50s), but didactics and presentation left much to be desired, it is very difficult to study it. I never read all that stuff in full, but from the chess books I once had, on endgames this is the only work that survived.

The stuff I mentioned can be found in Volume one. Check any book shop, I assume there are many more accessible books on rook endgames available today. theory developes, sometimes dramatically, so do teaching methods. the old books not always remain to be the outstanding classics that they used to be when they were first published.

the problem is that the fact that once one has learned some of the millions of rules about endgames 25 years ago, and so knowing that they exist - and implementing them today shows to prove to me so very often the transitoriness of things, mind and memory. :haha: and who does not know the situation from sitting in a chess club and playing an opponent - and ruining the advantage one had gained in midgame in just another one of these terrible rook endgames. :har:. I certainly have had my share back then. So if i sounded as if I am well oriented in the matter, that impression to a major degree is wrong. and I find it easier to calculate midgame situations than endgames - but then, who sees that different.

Thanks for the info on Chéron, I will look out for it. As long as I am learning, there is no bitterness in defeat :)
