24.Nxf5 is winning but it is not the right way to analyze.
programs may miss the right defence in a game.
It is better to use a normal program for black and not storm because I do not
trust storm's evaluations.
After 24.Nxf5 Rxf5 25.Rxh6 normal programs see that white has a winning
advantage in a few minutes(evaluation of more than +3)
They can also see that black has no alternative for 24...Rxf5 without a bigger
advantage for white and the conclusion is that 24.Nxf5 is winning.
