If you haven't got a friend to go 1-on-1 against, then use this method
1. Whilst playing in a public stronghold, play as normal (just for the fun)
2. If you have died, then go to the menu option and select stronghold (do this with about 30 seconds remaining)
3. It should put you back in to the same game with 0 Kills and 0 Deaths
The above solutions are quicker but this was how I did it as I did not look for a boosting partner for this .
I thought of this on a spur of the moment, and it worked
