It may be better if White just tossed away the pawn to increase stalemate
chances which are very plausible OTB when the player does not have
access to his database (and is tired, also the clock is ticking).
White to play and draw in all cases.
I have a megabase of approx 4 million games.
Some of you will have to.
Set it to find K & Q v K & R and draws.
You will find a few players have failed to get this win under 50 moves.
It's not easy. Play it v your box, take the K & Q.
I've have had to do and win this twice OTB. Once in an allegro game.
I was lucky my opponents alowed me to win their Rooks.
I had no set plan in mind, just setting wee traps.
I have copied this from:
http://www.jimloy.com/chess/kq-kr.htm
King Queen v King and Rook
In 1978, this ending received some publicity, when Ken Thompson's
program Belle played this ending against Walter Browne.
The conditions of the game were that Brown, with the queen,
had to win the game under tournament conditions
(I think they started with this position).
In particular, the 50 move rule applied.
And if Browne was not able to win, then Belle would be declared
the winner of the challenge.
Browne overstepped the 50 move limit, and lost the competition.
Browne won a rematch, a second game played after Browne
had some time to prepare, when he captured Belle's Rook
on the 50th move.

Originally posted by dustycatThe thread is not over. Nowaskowski who is ranked 1600 resigned yet there is no evidence (since he had no outside help) that he should resign at that stage. Even a Q+K vs a R+K is not a walk in the park and the situation is Q+K vs a R+K+P
thanks much greenpawn34 for the erudite presentation...this pretty well answers my questions and then some....thus ends this thread.
Perhaps Nowaskowski can tell us why he resigned or do we have to guess why?
Originally posted by orion25I'm with you on this one. I'll sometimes continue to push in a lost ending on the site if I have some reservations about the other person's technique, but I have absolutely no doubt that the big W would pull it off.
Yeah, cuz there's no way weyerstrass knows K+Q vs K+R!!!

Your exact point being?

As one can see, there appears to be an amazing correlation between the moves made by the two players and the moves chosen by an engine.
No, this is not advanced chess. Advanced chess it's all about setting traps for the engine of your opponent. There openings like Hypo (where the engine cannot offer a reliable evaluation after the knight sacrifice) are frequent. The game in question is apparently an example where untitled players manage to play more computer-like than any other players in the history (OTB or CC world champions included).
Feel free to continue the analysis!

Yes, I know. My point is that there is an earlier post in this thread saying that both players in the game play "advanced chess". To then link the words "advanced chess" to a player already banned for cheating is almost like implying that W and N are the same. Don't you think so? I do.
Advanced Chess (sometimes called cyborg chess or centaur chess) is a relatively new form of chess, first introduced by grandmaster Garry Kasparov, with the objective of a human player and a computer chess program playing as a team against other such pairs.[1] Many Advanced Chess proponents have stressed that Advanced Chess has merits in:
* increasing the level of play to heights never before seen in chess;
* producing blunder-free games with the qualities and the beauty of both perfect tactical play and highly meaningful strategic plans;
* giving the viewing audience a remarkable insight into the thought processes of strong human chess players and strong chess computers, and the combination thereof.
Originally posted by toeternitoeYou haven't seen 2700 or 2800 GMs blundering or missing tactical kills have you? Where have you been since the inception of chess?
Think I have to disagree with these proponents.
Blunder-free and tactical perfect?
I doubt it.
Remarkable insight?
How?Are they personally going to explain it to me?
I'd already be happy if they came to explain their GM vs GM games without the engines 😉
toet.
Advanced chess is not played only by GMs. People like Ironman allegedly did so and beat the hell out of everyone. Someone ranked 1500 "in the flesh" could play at 2400-3000 level as a centaur and beat Magnus Carlsen "in the flesh".

Yes I have .Fairly recently even a mate in one,Kramnik I believe.Where have you been?
I also remember a missed mate in 4 in a WC game by Korchnoi against Karpov.Even I saw it.It happens.
And,uhm,the fact that I don't spot a missed tactic doesn't mean there wasn't one 😛
Same goes for the machines,they don't play perfect chess and I don't think human input will make it perfect either.
But that's just my opinion,kinda hard to prove either way.
toet.
