Drawkiller_Big contains 29677 different opening-lines:

drawkiller_lines + 8 pawn_plies, all Komodo evals in the interval:
[-0.49;-0.10][+0.10;+0.49]

Because the draw-rate in my testrun was a little bit higher, than for
drawkiller_normal and drawkiller_tournament, it is recommended to use
the Drawkiller_big openings and books for very large testruns/tournaments,
only: For example, engine developers should use it, to measure small 
improvements of single patches...
For all "normal" testwork and tournaments, use the smaller Drawkiller-sets,
because the draw-rate is lower!
