I've checked these numbers with crafty. Note that you need 8 ply to have a 3rd repeat cutoff. Here it is: Ply| Number of nodes | Total # nodes | # Nodes / Prev. # Nodes ---+-----------------+---------------+------------------------ 0 | 1 | 1 | 1 | 20 | 21 | 20.000 2 | 400 | 421 | 20.000 3 | 8902 | 9323 | 22.255 4 | 197281 | 206604 | 22.161 5 | 4865609 | 5072213 | 24.663 6 | 119060324 | 124132537 | 24.470 7 | 3195901860 | 3320034397 | 26.843 Regards Andreas Stabel
