Summary on the Irish Brandubh.
The attackers can be set up in three ways, here called cross, circle and line.
To that comes that the board can contain a throne square or not. The game with a throne will be called Brandubh, and the game with no throne will be called "Brandubh throneless".
This makes in all 6 possible initial setups for the Brandubh 7x7 game. In any case the Brandubh king is armed, is captured from two sides and wins in corner.
The game balances for the 6 setups were measured through test tournaments:
|Board setup||Brandubh throneless||Brandubh (throne)|
||-2.50 (21 games)||+1.34|
||-2.00 (15 games)||+1.55|
The measured game balances confirm, that a throne square protects the king and is a help to the defenders.
The best balanced setup was found to be Brandubh cross.
As for historical evidence, the Ballinderry board has marked corner squares and a marked throne. Our test games show that the Brandubh cross setup fits this board.
