Random Gaps + Pie Rule

So adding two components to a graph that are homomorphic to each other (i.e. two identical “islands”) doesn’t change the value of fair komi. So when playing on three 9x9 boards, you should have the same komi as when playing on one 9x9 board.

However personal preference also plays a role. In the “komi needs correction on 9x9”-thread, the point was made that some value may be “fair” in a theoretical sense (that is when assuming optimal play), but maybe in some strength ranges, players don’t know how to utilise playing first and countering komi. No problem with the pie rule! Just adjust komi according to your personal preference. If you enjoy playing first and feel confident giving white 10 points komi, you can go for it.

//Edit: The downside is, it introduces another hurdle for beginners. You have to make a couple of decisions before you can begin playing, and the rules have no intrinsic feature telling you what is a good choice.

This might not always be true if we take ko into account! Even if one player is always mirroring the two identical islands, the other player can use such exchanges as free ko threats.

Oh yea, a7 is an eye for white. Totally missed

Assuming superko, it is actually possible to break mirror go without using the middle of the board! It’s hard for me to visualize. So here, I made a demo: Mirror break

And in the process I discovered that of course it’s already on Sensei’s: Countering mirror go at Sensei's Library

So I think your double-island games might still be playable.

– Since you’re a bit stronger than me I was curious if/how you would invade, and I thought it would be harder for me to do the same if I picked white :stuck_out_tongue:

I think I had to try some sort of invasion, but it looks quite difficult to live here!

I play B9.

Sorry I’ve been a bit busy/tired.

A8 otherwise I think it just lives with A8.

I dunno I imagine you’ll live easy enough.

The situation has improved from “I’m pretty sure I’m just dead” to “I’m probably dead, but I have no idea what’s going on” :stuck_out_tongue:

I’m looking forward to discussing this afterward. Was thinking of making the game into a gif too, for fun :slight_smile:

I think this might be heading towards a big ko.
