The Fetlar Hnefatafl Championship tournament 2012
is completed! 156 games were done by 13 participants from 8 countries on 3 continents.
Congratulations to Tim Millar for the win!
There were 82 white wins, 66 black wins and 8 draws;
a fine balance with a slight overweight to white.
The draws are 6 center forts, 1 perpetual check and 1 case where white is blocked and cannot move.
The game lengths show an interesting regularity: when white wins, the games are nearly precisely half the length of games where black wins.
The game lengths are log-normal distributed and the statistics are
for white wins:
shortest game 15 moves,
longest game 86 moves,
mean game length 38 moves,
most probable game length 25-58 moves.
for black wins:
shortest game 35 moves,
longest game 155 moves,
mean game length 81 moves,
most probable game length 59-111 moves.
The figure illustrates the experience from real games, that white must win fast, or else in a prolongued game black will win.
