It’s rather poetic. We have the king; the most important piece in the game which must be protected at all costs; and the queen; a piece stronger than the next 2 most powerful pieces combined. In the above position, the almighty king and dominant queen both find themselves unescapably ensnared by a single, lowly, well positioned knight. The royal fork reminds us that it doesn’t take an army to push around 2 towering, seemingly unassailable pieces…..just an idea and stellar execution.

I think this serves as a decent metaphor for bitcoin. Like the knight, Bitcoin has positioned itself squarely between 2 giant institutions; the State, which regulates the monetary system, and the federal banking system, which runs the monetary system. Unlike the chess analogy, I don’t think the relationship between Bitcoin, States, and banks is or should ever be adversarial. Chess has clear winners and losers; the real world can accommodate success for everyone.

Sorry to post this here, but this is the only active thread I know about chess and Bitcoin. I used to read and reference many others to royalforkblog.com. It was an excellent blog about Bitcoin. You can find an archived snapshot here: https://web.archive.org/web/20150214051116/http://www.royalforkblog.com/

Does anyone know who ran this blog and why it is no longer online? It went down probably 2 month ago.

I am the type of learner that profits from the beautiful style. e.g. check out this:

I even had e-mail contact with the guy once but it was all through the royalforkblog address.

Sorry for interrupting the chess game. In case you know anything, please pm me.

I found the beginning of the solution:

2. Kb5 Rd5+
3. Kb4 Kb2
4. c8Q Rd4+
5. Kb5

I know that the white Queen has to capture the black Rook by simultaneously putting the black King in check.
I know that the checkmate would be something like that:

or

But I didn't succeed for now.
