Adam, first welcome to the site...it is a great one ! To answer your question, when you hit the "Play Now" button upper left it takes you to the green main menu screen..of course you know this. But select match play middle left column...then select "Challenge" on game mode right side...then select invite players bottom right...then select player rank and filter to amateur+. This will be your best option to find a random match play challenge with someone with "like" abilities. Just refuse the match if they are tiered too high for you. But the most certain way to do it, is by collecting friends on your same level or maybe only 1 or 2 tiers higher than you....then you can filter to friends and have better luck setting up an equal match...

EDIT....I see you have joined a Country Club, that is an even better way to collect friends of like abilities.
