First, I am going to set some ground rules.

– Neither I, nor the bear have access to advanced weaponry (knives, guns, bear spray, human spray, etc)

– Specifically a female black bear.

– I do not need to kill the bear, only fight back enough to discourage it from fighting.

– Both the bear and I get to listen to hype songs before the fight.

The stats:
(All my stats I found from bearbiology.org – I trust they are accurate but I apologize if they are not.)

– Female black bears weigh between 90 to 180lbs. For sake of argument this bear will weigh 180lbs.

– Female black bears are between 4ft and 6.25ft tall, when standing on back legs. For sake of argument this bear will be 6ft on its back legs.

– I weigh 220lbs, 5’11, am well built, and am quite used to tossing around objects weighing much more than 180lbs. I’ve also played contact sports my entire life and box.

– I have that dawg in me.

The fight:

In a boxing match, the bear wins as it is much stronger. I would also be unable to run away as it is much faster.
So neither of these are viable options. Thus I only see two options in which I emerge the victor.

The first way would be for me to choke the bear out. I would need to avoid its mouth and paws, but if I was able to get behind it due to its poor eyesight, I genuinely do believe I am strong enough to choke it out – 180lbs isn’t that much, so i’m certain that its neck circumference and strength of muscles would not be too much for me to suffocate with my arms.

The second way would be for me to blind it. In this scenario I would be fully prepared to sacrifice an arm, and while the bear is attacking one arm with its teeth, I would use a stick or fingers with my other arm to try to blind it. I am aware that bears have small eyes, however in a close vicinity (with one arm in its mouth) I believe I would be able to hit my target.

TL/DR : I could beat a female black bear in a fight by blinding it or choking it out.

EDIT: I have been informed that bears do in fact have good eyesight.
