Summary on the Irish Brandubh.

Ballinderry board.

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)
Lewis diamond
-2.50 (21 games) +1.34
T cross
-2.00 (15 games) +1.55
Lewis cross
-1.46 +2.27

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.
