In Response To: Another from Kaz-Tardieu 1999 match (Peter G.)

The three point is indeed best with cube access. Albeit the equity range is not what I hallucinated it to be and I came to the right conclusion for a wrong position using way off assumptions. ;-)

The score (after 0 games) is: White 1, Blue 4 (match to 15 points)

Move number 3: White to play 43

White	147
Blue	172
Position ID: g/NggFjGrsQACw Match ID: MAHuARAAIAAA

• White moves 8/3 6/3
