This leads me to believe that Johan, once again, is using "experimental" settings of some kind. Did Johan actually announce Mate in the tournament? 24...Bf8 leads to an easy mate to find, but it seems that other moves (that also lose, such as 24...Qe4) might not....

It finds Bxh6 AND loses it in less than one second, and doesn't find it again until 9:16! Up until then, the difference in eval between that move and Be3 is about 0.3....
