Only raises I ever make in PLO except in the last 3 or maybe 4 seats are pot-sweeteners with above-average drawing hands or double pairs, daft stuff like min raises or putting in a couple of BBs, plays that make you look a bit of a gimp to the rest of the table. Good for the image against better players too.
But yeah, I don't raise much if at all in the early seats, and never raise "classic" raise hands like AA. I CERTAINLY never re-raise from early unless I can get most of my stack in with a monster.... Nice article.
