Today, for the first time, I played against the Chrome app Shredder Chess, and at the "Hard" playing strength of the engine, I was easily able to beat it.

I am just about 1850-1900 Elo. My question here is, what (Elo) strength does this engine play at? Can someone evaluate?

I would suggest players to play against it to check its strength.

I played a few very, very fast games and I would estimate that it is no more than 1400 strength, maybe less, although tactically it might be as strong as 1600 strength. These are just my own estimates, so take them with a grain of salt. –  Andrew Sep 29 '12 at 5:12

This is a response from the maker of shredder. Hope it helps!

We are using a different Shredder version on the Chrom App so this is very hard to tell in Elo, even for us.

So the Shredder people don't know how strong their app is. Really? Really? –  Tony Ennis Jan 1 at 23:59

This answer keeps the question unanswered. How can this be accepted as an answer? The Shredder people say it's hard, but why? And because it's hard, doesn't mean it is not possible to determine ELO strength. –  Rafiek Jan 3 at 13:44

I can quite easily beat the iphone app when it is supposedly playing at 2600 Elo. I'm not that good! Very disappointing really.

It's a bit silly to determine a chess engine's rating by letting human players play against it. All chess engine ratings are determined by letting engines play each other.

You should download a range of rated engines and let them, including the Chrome app Shredder Chess, play in a round-robin tournament. This will give you a good rating estimate.
