I do not think that the word sacrifice is correct here.

4 pawns is considered to be more than a piece so the player that sacrificed was
yace but it seemed that yace was outsearched because yace evaluats the position
at move 26 also as better for hiarcs.

There are 2 possibilities:

1)Yace was lucky to be outsearched and got a winning position that it did not
understand.

2)Hiarcs blundered some moves after getting a big advantage by winning 4 pawns
for a piece.

I did not check to find which possibility is true.
