Re: [gnugo-devel] fuseki-lookahead, avoid a big move-heuristik

Hi Andreas,

thanks for your testcase, I will add it to the regression tests.

The idea is certainly there, but we don't have concrete plans to
integrate it into gnugo yet. I do think we need it, though.

I am doubtful about trying to add such principles explicitly to the
code. Instead the engine should understand it implicitly from its
general algorithm of move selection. If the opponent has a big
territorial move somewhere, we certainly do that already (i.e. the
territorial damage/gain it creates are implicitly included in the
territotial valuation of all moves that do not prevent this specific
opponent move). With respect to opponent moves with big strategic impact,
our move valuation is certainly improvable. Here, a global lookahead as
you suggest above would automatically take this into account.
