1) How easy was it for you mentally in the beginning playing HU (both cash and HUSNG)? I have personally noticed I get worn out way faster playing 1 table HU vs 20 tables of SNGs.

2) When studying a HU match. What are some things you look for in order to improve?

3) What qualities make a difficult opponent?

Perfect timing on this (for me anyways)! I've been going over my HU game a lot so this will be a big help.
