Caught the wrong fish?

Treasure chest was in Wyoming,just let me guess...Forrest Fenn is a genius grandmaster,when it comes to chess!

His moves are timed and gauged,light years aheadThe rules of his game are not written,not even said

Some people were competingin knowledge and witsSome people played the scouts,some people - blitzs

Some people jumped to decisions,but I liked to waitI loved the man,very deep I swallowed his bait

First and foremost he's an anglerone hard to matchI knew what he wanted,I could have been his catch

Only, he let me goThanks for relief!My magic wouldn't have workedwithout belief.

I am a teenyvery tiny golden fishWhen caught, I bargain for freedom,I could grant someone's wish.
