That solution sounds simple to you???
Is that how you start all of your games? By making personal invitations? What, am I suppossed to go through the list of all the thousands of players and their profiles just to find a compatable player????

NO!

Starting an open game makes way more sense. We just want one more filter option when starting a new open game...... You have not yet told me what is so bad about that request???

Answer this question Ug, or anyone.....

What is the substantive difference between an 'ability' rating and a 'speed of play' rating?

If this site didn't use bkr, imagine the fits you would have trying to find a chess game with someone of your caliber. Imagine getting stuck playing with someone like me all the time, because you didn't have the ability to filter you games with opponents of a certain bkr level???You would be complaining relentlessly, and you would not appreciate me telling you to go through everyones profiles and look at their past games to determine for yourself how good they are at chess, and whether they are worthy of a game!
