I think this fight with Rambong Choochai (they had at least two fights) should be posted to show the amazing heart of Rambaa Somdet. He never gave up and when his back was against the wall that's when he seemed to fight the hardest.

Rambaa's fights with Rambong remind me of another favorite fighter of mine MMA great Sakuraba, and his fights against a bigger Wanderlei. Brutal stuff.
