I played like 10 PS 2.20 SNG's yesterday.
General feeling is that HU play there was just afwul. Briefly my experience are the following:

- Way too passive preflop
- Almost no 3betting
- People stack of way too light
- Betsizing (pre and post) made no sense
- It's a shame there's no micro limit HU cash because it usually takes only 1 big or 2 medium sized pots for the game to became shove/fold.

I REALLY enjoyed playing HU and my feeling is there's way more theory in there and edges between players can be huge imo. Compared to the robotic decisions at 6max nowadays it felt great, so I'm definately going to be playing some bigger games.
