We give simple and general explanation to the effect of unbound acceleration of particles by black holes. It is related to the fact that the scalar product of a timelike vector of the four-velocity of an ingoing particle and the lightlike horizon generator tends to zero in some special cases, so the condition of "motion forward in time" is marginally satisfied. In this sense, an ingoing particle with special relation between parameters imitates the property of infinite redshift typical of any outgoing particle near the future horizon of a black hole. We check this assertion using the Reissner-Nordstrom and rotating axially-symmetric metrics as examples.

    For extremal charged black holes in any dimension and with any cosmological constant, a fine-tuned near-horizon particle collision can eject a particle carrying arbitrarily large, though finite, energy.
