1) Moving up is the most important thing at microbonk poker.
2) Most microbonks cannot play postflop properly.
3) Opening KQ UTG at FR gets you into silly marginal positions postflop a good portion of the time
I've seen loads of people say "nits" etc to folding KQ UTG, but I've also spoken to/read/watched things from winning FR players who say KQ isn't in their UTG range...so it's up to people to decide how they want to play.
