Irrelevant, as long as it chooses the key move.  It gets a new turn after the
opponent's response.  Besides which, Phalanx, after a fairly short think, got
plenty of the pv right...

Here is what Phalanx said, compared to the analysis that was proposed
phal:Nh4xg6  Kh7xg6  Qc2xf5  Kg6-g7  Be2-d3  Rf8-h8 Qf5-g6  Kg7-f8  Pe5xd6
anal:Nxg6    Kxg6    Qxf5+   Kg7     Bd3     Rh8    Qg6+    Kf8     e6
You will notice that the first disagreement is the fateful and difficult pawn
move e6.  So would Phalanx get it wrong?  I doubt very much if (by the time
Phalanx arrived at that position) if the move chosen would not be the correct
one.

Of course, to say that chess is solved by having a program that chooses the
right move to this problem is directly and more absurdly akin to:

"I have sucked up this eyedropper of seawater and examined it with a magnifying
glass.  Therefore, we know all that there is to know about the ocean."
