Yep. Pretty typical, agreed.

It is from one of my own games, and I am fascinated with the backward analysis
feature of Yace. So I tried to prove a significant score in post-mortem.

I take it you are joking :). Anyway, I was surprised that the h-pawn is enough
to win and that the first move does matter. But then I am no master player.

This is the one José was talking about btw, I guess you will remember when you
see it:

Topalov,V - Shirov,A

Another endgame :).
