Who was killed by the "Chakravyu Neethi"

Abhimanyu, Arjuna's son, was killed in the Chakravyuha (wheel formation) on the 13th day of the Kurukshetra war. He knew how to enter the formation but not how to exit, having only learned the technique while in his mother Subhadra's womb (Arjuna had explained the entry, but fell asleep before explaining the exit). Trapped alone, he fought valiantly but was ultimately killed by the combined Kaurava warriors. The spelling 'Chakravyu Neethi' in the question is garbled.
