Interesting rating estimator

I found this rating estimator at a chess blog..

follow the instructions exactly and it will give you an approximate rating.

http://www.chessmaniac.com/ELORating/ELO_Chess_Rating.shtml

Estimated ELO = 1785
Seems fairly accurate.

hmm, said I was about 1685... ok, I can live with that.

If you can post your Elo and the estimate rating so I can make graph and analyze it.

2060

I wish it would give you feedback on which answers it disagrees with...

Here are my answers

1. f6 - f3
2. h5 - g6
3. c5 - c6
4. e5 - e6 {with Bxe6, Bd1! to follow when blacks bishop is where his king should be so white will be able to play Ke5)
5. e3 - c5
6. c3 - d5
7. f6 - h7
8. c8 - e8
9. e4 - b7 (this one disappointments me. My intuition screams that there should be an attack on the king but I just can't find it. Bh7+, Kh8, Bg6!? looked interesting but doesn't get anywhere and Bxh6 also seems to fail)
10. c8 a6 - didn't give this one much thought, it's just an old nizmo strategy to team up on the c4 pawn.

2150.

I differed from Z on six answers. A lot of difference I think to still have reasonably high scores. I changed one answer and it changed to 2230.

Probably best to let folks work on it themselves for a while.

1615

1840 😀

Not all of the answers will be some complex tactic...Some of them can be as simple as a pawn or Knight move which may only make your position slightly better. It is these subtle moves that make the difference between an amateur class player and a Master... Sometimes instead of executing a royal fork and giving up a rook it is better move a pawn and a gain two minor pieces...

Oh and also there are clearly more correct answers than questions. Some of the questions have two or three answers where all of them improve the position but one will give a higher score than the others...

So in theory one could miss six of ten but the four he got right could have all been best solutions, thus he scores 2000. However person B might score nine ten but never get an optimal solution and thus have a 1700 rating...I also notice from the few scores I've seen here on RHP that the correlation between RHP corr. rating and the estimate given are closer as the ratings increase. Sorry for the long winded post...

2270-quite chuffed : ) My elo is 2210, so reasonably accurate.

A few (3 i think) were simply patterns/tactical motifs I'd seen before, so easier to spot. #1 looks like opening theory. #8 was cute though.

Your elo is pretty nice. You should go out there on RHP player tables and fight for the first place on the table.
I like when strong RHPers have OTB chess background. Too many cheaters on the first table page 🙁

1810....is that good?

I've never played OTB, but this things gave me a rating of 1365. Does that mean this thing says I'm a class D player? That would be nice.

I'd be interested in seeing your answers. I came up with 2235 and I've gone back through them again, but I don't see any improvements I could have made.

I first tried to do it last night at 2 AM when I was falling asleep and only scored 2045, which shows the effect sleep deprivation can have on your game. I looked again today after a night's rest and some of the moves I'd missed last night jumped out at me.

Interesting; thanks for the link! 🙂

Hey no problem, I'm glad I could provide some stimulating software for you to enjoy. I got a 1960 first try and after messing with my answers and trying my second choices I couldn't do any better...

Maybe someone with fritz or rybka can run the answers through to see what the best score possible is... I have Crafty and a weak Fritz but I am running on a 700MHz celeron machine with 192 MB of RAM so I don't think I can find the best solutions...
