In Response To: 54S-43H-53D-63R-42 (Nack Ballard)

Here is a nacbrac summary of Tim's original position (with 13/8 and 13/10 both brought down), my first variant (with only 13/8 brought down), and my second variant (with only 13/10 brought down), respectively. Each of the three positions has a different best play.

54S-43H-53S-63R-42 [P B15 r22 b24] "<=25
54S-43H-32H-63R-42 [r P21]"<=20
43S-43H-32H-63R-42 [B b12 r31 P46] "<=20*5

Key: P = Point (8/4 6/4), B = Both (20/16* 10/8), b = both (24/20 10/8), r = run (24/22 20/16*).

Rollout details of the original position can be found here: 20k 5k.
Rollout details of the two variant positions are posted below.
