since you did a lot of work for Queen and pawn versus queen endgame over a decade ago

Was wondering if you might be interested in giving Queen versus rook endgame (which I created today, because I was surprised it didn't yet exist as its own page) a quick look. Your suggestions would be much appreciated, even if you don't have time to work on it. :) Double sharp (talk) 18:20, 28 September 2024 (UTC)

.OK. I looked at it briefly and thanked you for the edits. Bubba73 19:48, 28 September 2024 (UTC)

Thanks!

Do you think there's any other endgames that we should have standalone articles on? (Off the top of my head: maybe NP vs N, BP vs B, BP vs N, NP vs B, R vs N, R vs B. Well, I guess BB vs N would be fun, but are there that many sources? Dunno why Russian Misplaced Pages has an article on Q vs N/B, since that's pretty straightforward.) Double sharp (talk) 15:53, 29 September 2024 (UTC)

Those are all interesting to me, but I don't know if they need an article. There is Rook and bishop versus rook endgame. Bubba73 02:32, 30 September 2024 (UTC)

The thing I find most interesting about Q vs R is the fact that it's not generally won on arbitrarily large boards, which perhaps explains its difficulty on 8×8 – there's not really a deep reason why it should be won in some sense. So perhaps morally the best way to do the B+N checkmate is the triangle method, since that generalises to arbitrarily large boards while the W-manoeuvre doesn't.

And Q vs R+P (which I felt needed to be a section on the Q vs R article) is really complicated. :( Double sharp (talk) 03:46, 30 September 2024 (UTC)

I didn't know that about Q vs R on large boards. I've had R+P versus Q at least twice, and drew them. Bubba73 04:27, 30 September 2024 (UTC)

Cool! Out of interest, where was the pawn? :) Double sharp (talk) 04:39, 30 September 2024 (UTC)

I think both were knight pawns. Bubba73 23:16, 30 September 2024 (UTC)

Makes sense. From what I remember reading to write the article, they give the best drawing chances. Double sharp (talk) 03:10, 1 October 2024 (UTC)

Well, when I made that list in the comment, I was thinking firstly of (1) whether it's common and (2) how many subtleties there are. That's why I didn't consider RN vs R, because it is almost always drawn, and much more easily than RB vs R. And, well, the importance of RP vs R and QP vs Q suggest doing the minor-piece equivalents as well.

(It strikes me as a slight pity that Nunn changed his mind and did not include BN vs N.) Double sharp (talk) 06:19, 30 September 2024 (UTC)

BTW, another thing you might find interesting from H. G. Muller's investigations: it seems that some of the weakness of the R in 1v1 pawnless endgames comes from the fact that the R cannot force mate by itself without zugzwang, and the defender thus needs to be reduced to a bare king. A "charging rook" that replaces the backward moves of the R with those of a K actually wins in general against B or N, because it does not need zugzwang to force mate!!

Another fun fact from his work is that the Karstedt fortress in Q vs BN will hold for the weaker side even if you give the Q the N's move as well. (But good luck getting to it, I imagine.) Double sharp (talk) 10:52, 30 September 2024 (UTC)

I was impressed by Q verses two minor pieces in Fine's Basic Chess Endings, but tablebases changed much of that. Bubba73 04:04, 1 October 2024 (UTC)

The empress (a R-N compound in the sense that the Q is a R-B compound) oddly differs from the Q here: it beats all three pairs of minor pieces (NN, NB, BB), but the win against the bishop pair sometimes gets cursed by the 50-move rule. The princess (a B-N compound) does worse as expected: the only pair it has significant winning chances against is NB, and even then it sometimes gets cursed by the 50-move rule. (Source.) Double sharp (talk) 05:15, 1 October 2024 (UTC)

A friend of mine was into fairy chess, but I never got into it.

You were asking about R+P vs Q. One of them was memorable. It was at a club game and I was behind in material. My daughter was there, but she had finished her game, and I went over and tried to get her come watch my game, because I had a plan. (But she wouldn't come over and watch.) I sacrificed material, leaving the opponent with only a pawn, which queened. But I had R+P and an easy draw. Bubba73 05:28, 1 October 2024 (UTC)

Interesting!

I kind of think that most of the pawnless endgames are academic. Apart from Q vs R, R vs minor, and R+minor vs R, they don't seem to be all that common in practice. So in that sense, the fairy versions are only slightly more academic, as are the versions with differently sized boards. But they can sometimes be illuminating as to what exactly is going on that makes the orthodox versions difficult, like the comparison above where it seems that the R's inability to mate alone without zugzwang is behind what makes R vs B and R vs N general draws on 8×8. Then again, I just realised that Variant Chess 60 mentions that R vs B is generally won for the R on 6×6, 6×7, and 6×8, but is generally drawn on 6×9, 7×7 (doesn't matter which colour the B is on), 7×8, or 8×8. So maybe it is still more complicated than that.

The late John Beasley conjectured in the same VC issue that for any n, there's some sufficiently large board such that king and n knights cannot mate the lone king. I'm unaware of later results resolving this either way, but would tend to agree with his intuition.

(BTW, I kind of feel that the B-N and R-N compounds are somewhere between "fairy" and "orthodox", as they're so easily described in terms of standard pieces and Capablanca proposed to add them to standard chess. And maybe cases with same-coloured bishops are also somewhere in that limbo, because even though they can be reached by a legal sequence of moves, it seems unlikely that it would ever be the best move to underpromote that way. But YMMV of course.) Double sharp (talk) 05:40, 1 October 2024 (UTC)

a chess endgame question

Asked it on the refdesk, but didn't get an answer, so maybe you know.

In the endgame of R + B + wrong rook pawn on R7 vs R (where the enemy king is sitting on R8 blocking the pawn), do you have to give up the pawn to make progress? Double sharp (talk) 16:28, 27 October 2024 (UTC)

Good question. I watch some of the refdesks, but not always. I salvaged a draw in a crucial tournament game in 1972 because of the wrong rook pawn, and I studied it afterwards. It has happened since. But offhand, I don't know. I have a very large collection of endgame books, but I am in the process of moving to a new house (within 2 weeks) and all of the books are at the other house.

I do remember something similar with a R+RP versus B, with the king in the corner, but the RP was the RIGHT rook pawn. But the stronger side had to give up the pawn at the right moment to get to a won K+R versus K+B endgame (which is generally drawn). So he pawn might have to be given up. Bubba73 22:30, 27 October 2024 (UTC)

Some R+B vs. R positions are won, so you might have to give up the pawn when the resulting R+B vs. R position is a win. 23:11, 27 October 2024 (UTC)

Thanks. Yeah, from looking at specific positions it seems plausible that once you bring the king to support the pawn, the defender gets forced into very passive rook placement, and the resulting R+B vs R will be won. I was however uncertain if this procedure works in general, and if it is the only way forward. Double sharp (talk) 06:46, 28 October 2024 (UTC)

That is what I've been thinking too. You could try it with a chess engine or endgame databases. Bubba73 01:13, 29 October 2024 (UTC)
