First of all, thank you Aage for giving a test to these ideas!

I don't know how the balance could move, but if I refer to this:

.../... I've compared it to the game on Dragonheels' Lair that uses my old rules. Of 314 games, there were 144 white wins against 166 black, with 4 draws. Using Aage's notation that, I think, gives a balance of -1.15 overall. .../...
The rules quoted above could be found there: http://www.dragonheelslair.com/en/rulesbrandubh.php

Main changes are that King is captured by only 2 attackers everywhere (even on throne) and the throne is not hostile. This explain why the balance is -1.15.

This is why I proposed something a bit less in favor of attackers. Even if I suspect the "noreturn" variant will be the more balanced.

It could also be possible we have to combine the 2 variants to balance the game. ;)

We've done several games Hnefihunter and myself with [king2nextthrone + noreturn] and it shows it's too much in favour of attackers.

We don't know king2nextthrone's current balance but it looks pretty good to us.

Measured Brandubh game balances at the moment:
Ordinary rules: +1.49
King cannot return to throne: +1.36
King captured next to the throne by 2 blacks: +1.08
- And your experiments with king cannot return AND captured next to the throne by 2 blacks: << 1.08

Hagbard, did you compute king2nextthrone balance now tournament 146 ended?

Yes, just did: +1.11
So king2nextthrone stood its ground after a test tournament and 140 test games.

Very good. It was also my feeling while playing. It makes the white job harder.
