Hi,

Let's say you have to do an opening, but with a given theme that would be "Fibonacci"...
What would you do ?

here is mine :
hint : black plays 1 1 2 3 5 with "sansan" being "1"... and also took some liberty as this is not exactly the "Fibonacci" shell...

On move 3 I'd play two stones. :mrgreen:

I played around with a few Fibonacci sequences, here's what I came up with:

First, I ran the algorithm on a 17x17 board "centered" in a regular 19x19 so that it would stop playing dumb looking 1st line moves =)

I started with 3-4, 5-3 (translated to 2-3, 4-2 in the smaller, centered board). Then for each subsequent move I added the two previous x and y values, modulo 17.

2-3, 4-2, (2+4,3+2)=6-5, (6+4,5+2)=10-7, etc. etc.

Here's the first 36 moves, since move 37 is a repeated position and I guess black loses for trying to balance a second stone on top of the existing one?



I could totally imagine this being played by two absolute beginners.

It would be interesting to try playing Go where the number of stones you each place in a turn is based on Fib MOD 3 ...

B,W,B,W,B,W,B,W,(B)
1,1,2,3,2,2,1,3,(3)* (and repeat)

*Extra 3 stones played for B at the end of the sequence to give the same number of moves to B as to W ... was the only way I could find to give even number of moves.

EDIT: I mean to repeat the whole sequence, with White starting the next iteration. :D

I like that Idea, but I even don't know where to place the stones efficiently :lol:
