In Response To: 53P-54 3 ply (David Rockwell)

Thanks, David. Stick's XG 3-ply RO is [S D16] 5k and yours is [S D4] 62k, for an average of [S D5] 67k. That narrows the entry in Neil's 4-ply queue to 53P-54 (10, 5, 5).

Here is current "agg" (bot aggregate) for R, S and D in the xxP-54 positions:

61P-54 [S R1 D51]
42P-54 [S D40 R53]
53P-54 [S D7 R64]
64P-54 [D S26 R94]

Key: S = Split (24/20 13/8), R = Run (24/15), D = Down (13/9 13/8). Error sizes are in thousandths. For example, "[S R1 D51]" means that S is best, R is -.001 and D is -.051.

The deeper the opponent's point, the weaker R becomes and the stronger D becomes.

If you are reasonably fluent in nacbracs (Nactation brackets), which encaption the diagrams below, it should be easy to follow the progression (in order of: upper left, upper right, lower left, lower right).

61P-54 [S R1 D51]

42P-54 [S D40 R53]

53P-54 [S D7 R64]

64P-54 [D S26 R94]

Okay, now try reviewing the progression again, this time visualizing the respective positions (White has 7pt, 4pt, 3pt, 2pt) instead of looking at them:

61P-54 [S R1 D51]
42P-54 [S D40 R53]
53P-54 [S D7 R64]
64P-54 [D S26 R94]
