what do you prefer:

making open invites to games and letting anyone of any rating allowed to accept the challenge or

challenging based on ratings within a certain range?

I prefer team matches, most of which will fall within a given 200 rating range. I also enjoy the variety, and find tournaments a great way to meet opponents outside of my rating range.

I used open seeks with minimum rating specifications my first few months here, but not in a long time.

In live chess, I recently removed my minimum filter and seek so as to shorten the waiting period between games.
