In Response To: Three Point Anchor Games (Albert Steg)

Hi Albert, thank you for giving me a feedback. For the next time you can also send me email to let me know for sure. I found this thread by an accident.

The below is the position I showed in the lecture.

		White is Player 1 score: 0 pip: 132 Unlimited Game Jacoby Beaver pip: 110 score: 0 Blue is Player 2
XGID=---bBCD-C---bCa--aabbbb---:0:0:1:00:0:0:3:0:10
Blue on roll, cube action?

This is about the ideal structure for the doubler so moving his checkers towards forward usually hurt the doubler especially if it goes behind her 3 point anchor. As I mentioned in the slide, the gain in the race will not compensate a loss of giving more chance to leave a shot.

Instead, you have to move the taker's checker backwards to confirm my point (maximum take point is around 22pips).

This is an example.
