I suspect your position is a draw anyway.  But the point is in the position I
posted Pro Deo gave away the draw.  With tablebases it would have been able to
draw and save the half point.
Also it doesn't matter if you turn a draw into a loss or a win into a draw it's
still a half point you should not have lost.  It's even worse when you turn a
win into a loss and give up the full point.  Almost all modern chess programs
use tablebases now.
