After the prey played 15... Rfd8 i quickly played Qf2 moving away from the file.
This left my prey to have the burden to come out with a GM level plan or some FANCY move..
& he burned most of his time for that.
At the end when his time turned red & the alert sound peeped suddenly the prey resigned lol.
