Incorrect post m8.
There are two types of chokes in BJJ:
1. Blood chokes (which most pressure goes on the carotid artery ala Kata Gatame aka arm triangle) take longer to put you out.
2. Air chokes (which put more pressure on the trachea) these however put you out MUCH quicker.
Granted it's a little more painful Conor would've gone out had he let it ride just a couple more seconds, specially from a Cesar Gracie BJJ black belt.
POINT IS: Same choke with Holm and Conore, however Holly showed heart and Conor took the cheap way out.
PS Tates choke on Holly was more painful considering it was fully locked on trachea, yet she thugged it out, fought back, and napped.
