Jan-04-21		louispaulsen88888888: Black should. Have kept the rooks on the board

Jan-04-21		saffuna: click for larger view Position after 86 a8Q. Can black defend this position? If not, does white have to play perfectly to win?

Jan-04-21		Granny O Doul: White doesn't have to play perfectly. Just bring the king up, avoid forks, and play with zugzwangs to encroach further. One problem for the knight as a defender is that it can't make tempo moves.

Jan-04-21		saffuna: Thanks. What does that mean, tempo moves? It took a long time to win, 33 moves, from the diagrammed position.

Jan-04-21		Granny O Doul: A tempo move is the closest thing to a non-move that the rules allow. A rook or bishop sometimes can shuttle back and forth without losing control of any important squares. The knight can't do this at all.

Jan-04-21		saffuna: Thanks. When would you have resigned with black? Say white did not win from the position on move 86? Would that be considered blundering away a victory?

Jan-04-21		Granny O Doul: I remember a Fred Reinfeld book titled "How to be a Winner at Chess" which included a chapter on "When to Resign". It's been a while since I read it. I might have resigned to a master once I saw he was queening by force, if we're talking about a slow time control, as this looks to have been. In a quick game I'd play on hoping for tricks, particularly a knight fork (another thing about defending with a knight; you're unlikely to spring a stalemate trap). In this game, I'd say Black played on a bit past the point of seemliness, but since it was an international, maybe it was just one game a day, and he may have had nothing else to do the rest of the day. From the White side it wouldn't bother me if Black played on, as long as he was playing quickly. If he's hoping for a trick, after all, he needs to entice his opponent into playing too fast. Against a non-master, it might depend on how much of a non-master he was. I think once I was squeezed out of one pawn I'd lose a lot of hope against anyone. If I failed to win this with White, I don't think I'd show my face around for a while. Whether I gave up chess would depend on how much else I thought i had going for me.

Jan-04-21		saffuna: It certainly took Shivaji a long time, but he did win eventually. He's a low-rated master, and I don't know what Troff was rated nine years ago when he was 13.

Jan-04-21		Granny O Doul: As I recall, "When to Resign" was the third chapter of this Reinfeld book, so fairly early. He probably assigned it a higher priority than it deserves but he may have been writing for a particular audience. Kids generally are unlikely to resign prematurely, and sometimes their parents or coach won't allow it. The most respect I ever got from an opponent was from one who resigned about 15 moves in after advancing a pawn that weakened central squares for no good reason. He explained that it was his method of self-discipline to give himself the death penalty for the slightest infraction (if it matters, this was a g/30). I noticed quite recently that he now has instructional videos up on youtube, but this particular technique is rather an advanced one that I very much doubt he would give away for free.

Aug-10-22		Cassandro: 76.h7 is nice, ignoring the hanging bishop. Black cannot stop both the a- and the h-pawn at the same time.
