A variation of that "pokerlistings" article has been discussed here before
(LINK) and got trashed by most of the better posters here.
Based on a quick skimming, the "noted poker authority" appears to be OK (looks like it was written by Ed Miller). I think it underestimates the value of being suited when you hold a hand like T987. This is probably because this is meant as a primer for
limit Omaha, not PLO, starting hands.
