Judit missed mate in 1 in this analysis
1rb2n2/p1p2B1k/1p1bpQ2/6P1/3P2P1/8/PPP2P2/2K5 w - - 0 27
Judith gives g6+ when Qh6# is faster.
unfortunately judit did not write a tree in order to convince yace that her
sacrifice was correct because some of the lines that she gives are trivial for
computers when she does not give lines that computer need to calculate.
The sacrifice may be correct but I was too lazy to try to prove it by a tree and
lines that computer cannot see in few seconds that they are losing like 17...e5
instead of the game move are not analyzed(I did not give the computer few
minutes for that line otherwise I may need to give it few minutes for a lot of
lines).
