Commit ID 7231b18af1ee62aeb523da1d1fbd5523b2cfa30b
Author Marco Costalba
Date 2015-05-03 18:07:52 UTC
Halve PSQT row data Use symmetry along vertical middle axis of the board to reduce the number of parameters. For instance psqt value of SQ_A5 == SQ_A4 and value of SQ_F8 == SQ_F1. This is always true, at least until now nobody came in with an asymmetric psqt table that worked. Original patch by Lucas. No functional change.
