Chess was brought to us by dolphins from the Pleiades!
The evolution of chess

The little history lesson offered by Fischerfan10 is a clear example of deductive reasoning based upon a week of seventh grade world history with neither the wisdom nor the necessary knowledge base to understand the nature of the Mediterranean world in the ninth century (Christian era).
What disturbs me the most is the following in the OP:
Around 500 AD Chess begins in Asia.
822: Chess enters Europe, through Spain.
Um...what? How many ways can I refute this? Firstly,just by a common knowledge, one should know that Asia and Spain are on opposite sides of the same continent.
Now a bit of history. A little thing called the Silk Road. You know, that gargantuanly historic trading route through which ALL of Europe travelled in order to reach China to trade for their precious silk. A secret the Emperor(s) kept closely guarded mind you.
This trade route was there until Constantanople, modern day Istanbul, fell the the Turks. Once it fell they then controlled a key travel location along the Silk Road and they were allowing no one passage through Turkey. As a direct result the Europeans needed a new trade route, so they set sail across the Atlantic, and Europe learned of the Americas' existence. The rest is history.
What this means is that Chess came from Asia and into Europe, through the Middle East, not Spain. I rest my case.
I moved from Baghdad to Cordoba in 822. I brought chess with me. I was the first to bring chess into Europe. That part of Europe was Muslim ruled, but diverse and tolerant. We had Jewish and Christian scholars among the predominantly Muslim elite of Cordoba in my day. It was the frontier of Arabic civilization and it was the most advanced portion of Europe for the next several centuries.
Others, in subsequent years, carried chess into the heart of Europe through Italy, and into Russia through the Caucasus.
