I think this is not true for all the moves. In go there are more moves
and hence more moves with obvious best move. But Game deciding moves
are ofter ones that great deal of thinking.

But also in chess I think there is a limit on what can be gained by
adding time. After so and so many minutes/move  your decision would
not be any better. In Go this is pretty common. Like when you play
someone 9 stones weaker and they spend several minutes pondering over
move and then come up something barely better than passing. If your
eval does not know enough of situation more searching will not help.
