Here is the answer to the Saavedra position I posted:


1.c7       Rd6+
2.Kb5     Rd5+
3.Kb4     Rd4+
4.Kb3     Rd3+
5.Kc2     Rd4
6.c8=R   Ra4
7.Kb3 and white cannot save both the rook and Rc1#

Any other second move for white would allow black to sacrifice his rook for the c pawn with Rd7 (if the king moves to b7 or a7) or play Rd1 followed by Rc1+ (if Kc5).

6.c8=Q   Rc4+
7.Qxc4 is stalemate

If I understand: underpromotion to Rook to avoid stalemate. I couldn't find it myself. For me, queening was obvious Smiley

Your move bitcointalk. You have the white pieces

The current position is updated below:

Nb3 for me too. Resign and Start over will even be better.  Cool

I agree with the resign option. If this was a real life game (other than blitz) I bet his opponent would resign here.

White to move and win:


I found the beginning of the solution:
1. c7 Rd6+
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:
http://lichess.org/editor/8/8/8/8/8/2K5/8/2k1Q3_w_KQkq_-
or
http://lichess.org/editor/8/8/8/8/8/2K5/2Q5/2k5_w_-_-

But I didn't succeed for now.


The line you gave is winning, but not forced. Look back in this thread for more clues about the problem. Kb2 is not the best defense for black on the 3rd move. Instead Rd4+ should be played.

Nb3 means we lose a Rook...

I vote for Ra2. Then next move can be b3 and we attack the Knight.

Ra2 loses to Nd4 and the deadly threat of Nf3+ cannot be stopped.

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:
https://web.archive.org/web/20150216123331/http://www.royalforkblog.com/2014/08/11/graphical-address-generator

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

excerpt from the about section:
Quote
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.

The most royal post so far was this one but a it is unfortunately not preserved with all elements:
https://web.archive.org/web/20150216055120/http://www.royalforkblog.com/2014/09/04/ecc/

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

Interesting blog. I did 60 seconds of research and found these which I assume are related:
https://github.com/royalfork?tab=repositories  (google image search of his face only leads back to github)
https://twitter.com/royalforkblog

Here is one more chess thread in case you want to ask there:
https://bitcointalksearch.org/topic/cryptonote-technical-discussion-and-chess-challenge-1190988
It is worth noting that one of the 52 accounts https://twitter.com/royalforkblog follows is https://twitter.com/hashbreaker who is someone important to those that follow CryptoNote

Good luck!
