An uncle block is a validated block that got a silver rather than gold medal, because another miner propagated a competing block more rapidly, and therefore won the “race” to become the next confirmed block on the blockchain. Uncle blocks get a fraction of the full block reward.

Is there any way to extract transactions in uncles?
As stated in the wiki:
Note: An uncle doesn't contain individual transactions.

I mined an uncle. When do i get paid?
There doesn't seem to be an answer to this question anywhere.

Ommer block forgery
What happens when two miners (PoW era) find the exact same solution to mining an identical block, and broadcast the solutions at the same time? I'm wondering if a miner could forge uncles this way in order to get extra reward almost every time it…

How do I compute the uncle block reward issued for a lock?
I have a bot that tracks the supply of Ethereum. I'm looking to figure out how to compute X where X is the amount of ETH issued to the miner for that block.
I believe, after EIP-1559, X = 2 + Y where Y is the Uncle block reward.
I'm not worried…
