Revert evaluation cache And return on using TT as backing store for position evaluations. Tests (even on single thread) show eval cache was a regression. In multi thread result should be even worst because eval cache is a per-thread struct, while TT is shared. After 4957 games at 15"+0.05 (single thread) eval cache vs master 969 - 1093 - 2895 -9 ELO So previous reported result of +18 ELO was probably due to an issue in the testing framework (a bug in cutechess-cli) that has been fixed in the meanwhile. bench: 5386711
