Through the left slanting corner into the hole, from there left to the top.
historical description: From the corner of the rock, there is a relatively significant slanting crack with wedged boulders. The most difficult section is in the lower third, which we overcome by lying on our backs, using the right hand to grip a wedged boulder. The left hand in the wall in a notch just above the head. From there, almost chimney climbing to the summit. The entire rock can also be climbed as a face climb, but this method does not fulfill the goal - i.e., winter climbing training.
