Wow! very nice....even I could see that one!
nice problem! 1168 yrs old!

This became the oldest known chess puzzle by a bit of luck... it's actually a Shatranj puzzle. In Shatranj they have elephants instead of bishops and advisors instead of queens and they move differently. But the rooks, knights, and kings move as they do in modern chess. So this Shatranj puzzle (out of all the many surviving Shatranj puzzles) by some luck excluded those pieces and ended up becoming the world's oldest chess puzzle. ;)

Another Shatranj puzzle (and how to make traditional piloff):

Alex, its from the book 'the immortal game' by david shenk, only had it 3 days , its proving to be a good read :)

the point of my post was'nt that i thought the puzzle was hard to solve, more that its pretty, and also i find it amazing that we can get enjoyment from something so old, and its cool to imagine people nearly 1200 yrs ago solving the exact same thing!

no, the point is that this puzzle dates from 840 A.D.
We (the chess history group) must look into the provenence of this... I posted to that effect in the group forum.
Someone should get in touch with you soon about this, gumpty :)

For group-invites to the chess history group contact qtsii or batgirl. [or maybe it is an open group now - one can just join. Either that, or I no longer have invite-rights for the group.]
UPDATE: Oh I noticed that likesforests [also a chess history group member] has implicitly vouched for its provenance. So it aught to be all right...

Okay it is authentic c.840 AD. Al-Adli's manuscript.
Bad news: Mr Bill Wall had already posted it on chess.com in August 2007!
