The Baron 0.99.4b2 (Athlon MP 2000+) finds it in just 8 seconds:

Unfortunately for Beowulf the game was already lost before 19.h3. I'd let the
Baron run on the position before 19.h3 and it didn't find a good alternative. So
I think 18.Qa3 was the mistake here. After 18.cxd6 the Baron values the white
position a little better here, but it is by no way convinced it will be a win
for Beo.
