Daily Quiz 23 march 2012
Number 1
The 4-anchor is extra strong with the wasted 3-point and the gaps on 5,7 and 9.
Answer: 24/21 11/10
Number 2
At first sight it seems there is no reason to take any risk because of the good blue racing lead. But on second sight I noticed that 65,63 and 61 play bad after the safe move (15/8), they leave a direct shot next move. Now the funny thing is that the indirect risk now of 64 (after 15/11 8/5) = 2/36 is equal to 1/6 (65,63,61) x a direct shot of 12/36. Since 15/11 8/5 creates more builders for the 7- and 4-point, this is my play.
Answer: 15/11 8/5
Number 3
There are 3 reasons why I think 20/18 6/5 is the best play here:
1st reason: 6/5 is good because white will (on average) have to leave his anchor sooner than blue, because of the blue racing lead. 2nd reason: The immediate risk of the blot on the 20-point is very small, a blitz is not advantegeous for white. 3rd reason: Blue has 4 pips extra playability in contrast to the variation 18/16 6/5, this might be handy because the blue points are pretty stripped.
Answer: 20/18 6/5
