Nothing Surprises Me Anymore.

Nice post GP...I found it Amazing How Knightmails Thread was removed? K&R V K&R...Come on this is a draw As for KvK! he cant resign as this drawn...end-of...if this is for real then i presume it must be a Gletch which im sure rhp will put right in due course now that they are aware of it.

I loaded the position from the thread in question into chess master, made the engine strength lopsided, and only allowed 1 second per move. The stronger engine eventually won.

I got in a little bit of a scuffle during a game where my opponent was convinced the position was drawn (k+r vs k+b) and I refused to accept the draw. I went on to win several moves later. Perhaps with perfect play my opponent would have got the draw he felt was inevitable. I know that at my level or chess play, the laws decreed by GMs writing books are merely guidelines.

The game I reference is here, with the first draw offer:

Hi PR.

See you may soon be No1. Get ready for the flak!

The thread was titled 'Advice Please' and it was a GIP.
What else could they do.
Leaving it up would have set a precedent.

Have a quite few examples where some of the lads have lost KR v KR
The most common being skewers or similiar to this one.


Black has just played 1...Kf4 and White wins with the check.

The lads are not terrible chess players, 90% of the blunders I've
seen would not happen OTB.

Here they have too many games on the go, they are playing an opening
in one game, conducting a sac attack in another, defending in another and
relaxing in drawn endings.

You could liken it to a continuous simultaneous display, when one game
finishes another player jumps into the empty seat.

How many average chess players do you know could give a good
performance v mixed opposition in a 20 board simul?
Not many, I can think of...er.....none.

But that is what they doing on here, hence the incredible blunders.

The K V K resignation is sound as are a few K v K timeouts.

I think the system should kick in and declare it a draw.
(but there again that would be outside interference).

Also recall posting one unlucky soul who resigned when
faced with King and two Knights v his bare King.

Edit:
Hi Darax

A good experiment that. Can you post the game or did it take forever?

no, and I just tried again several more games and it's 50 move draw every time now. oh well.

K+R v K+R may well be a draw but that still doesn't force anyone to accept a draw offer. In an OTB situation (or even an "official" CC situation) one would be able to call on arbiters and others to persuade the other guy that he is not going to get anything better than a draw, or even to impose the draw. Here, we just have to play on!

I set up an engine tournament between Rybka 2.2 at full strength with tablebases versus Shredder Classic 4 at 1000 elo, and used Knightmail's position when it first became a KR-KR game. (2 seconds per move.) After 20 games, Rybka has 8 wins and 12 draws. 😵

Typical human blunders.

Celsius I - Matth. RHP 2006.

White to play.


White chose 64.Kc5 after 64...Rb5+ 0-1

----------------

WoodRat - sameeh RHP 2009

White to play


White played 84.Kf3 Ra3+ 85.Kf4 Ra4+ 0-1

----------------

atlantean - Aanatol RHP 2008

Black to play.



Black played. 71...Ra6+ (71...Re7/Rf7/Rg7/Rh7 all draw)

72.Kc5 1-0



How does a box lose?
Please post one of the games.

Hi Dinc.

If I PM'd everyone before posting a game or an example then I'd
forever being doing PM's.

(however I usually PM a thank you to any game I use in the Blog).

All the games are the property of RHP and open to anyone on RHP.
I'm not making them up.
Of course I assume what has happened. It's part of the fun.
I enjoy looking for the odd ...[text shortened]... n.
It was the most extreme example I could find.

Tripe?

Yup that sounds like me. 🙂

If GP is Tripe, then I volunteer to be one of the Tripettes when he goes on tour.

thanks, I was feeling like a liar. 🙂

I don't know exactly, but the programmers make it "dumber" by removing knowledge, reducing tactical vision, and introducing randomness (read: blunders) into the calculations.

Lots of silly skewers like this one (moves 18-19):




And opposition blunders (move 11):




The king getting cornered (move 29):




This one looks familiar (move 24):

Cheers Mad Rook.

This thread is re-wrting the entire theory of Rook endings. 🙂

Have a really good example played on here which
I'm saving up for the Blog.

Here's several more losses by Shredder 1000 that caught my fancy.



A combined discovered check with an attack on the black rook at move 44:





And one where the black rook cuts off his king's only escape route (moves 46/47):






Move 12 blunder:

Well that settles it for me.
I have supplied the Human evidence and Mad Rook the
computer analysis.

A King & Rook v King & Rook is a win for both sides.

So here:


Instead of going for the Lucena position or 'bridge building'.

White should simply give up the pawn and win.

Thud!

That sound was my copy of Rook Endings by Averbach hitting the dustbin.

Next week.
How having 2 Queens means you are actually losing.

🙂 Ha Ha Ha good old greenpawn and his jokes.

middenlaan - joffrec RHP 2008


White lost this.

c guy1 - secret squirrel RHP 2008


White lost this.
(He got back rank mated a few moves later)

cevil - SlickMover1 RHP 2009


White to play has a mate 1...Qa8+ and 2...Qdxc6 mate.
Black has to play 2.Qa6 Qxa6+ 1-0

Instead 6 moves later White was checkmated.

Nothing Surprises Me Anymore. 😉

Agreed and Rec'd.
