*Parallelization: MPI ==> ~80% vs no mpi in 9x9 (for same number of
  cores).

*Monte-Carlo improvement ==> strongly depends on number of simulations
    and number of cores (as the multi-core reduces the influence of the
    computational overhead), ~55% I guess.

*Openings: 58%, for games with constant time per move (should be higher
    for games with given total time), if we only keep the openings which
    are still efficient in the new version of the code. Human-based
    openings do not work :-(

*less interestingly, we have a better hardware than at that time (more
    cores, more GHz).

==> no doubt that this mogo is by far stronger than the one at Amsterdam 07.

The improvement is much higher in 19x19, but humans are really too strong 
in 19x19 :-)
