This was taken while she was preparing herself for hunt.
The spotted deer was in front and she was making her move very slowly.
The tiger is a 'concealment and ambush hunter', carefully stalking prey, circling in as closely as possible, and then suddenly charging the target from behind.
In this case she wasn't successful , despite their range of abilities only about one attack in every 20 attempts is successful
