Wrong end of the bubble

Decided to delay my trip to foxwoods till this evening, so i played the 50 pot limit holdem, 50R both on stars (busted early), and on Dise the 30R and masters $200 Pot limit omaha. The Dise 30R paid 50 spots, and i ended up in 50'th position when under the gun minimum raised under the gun, like he'd been doing for a while almost every time he was under the gun. It gets folded to me in small blind, and I figure my 55 is the best hand, since I am sitting about 24/50 at the time, I figure I need chips, so it was a relatively easy all in, (remember, Dise structure=fast), utg calls and flips over ak soooted, and I lose the flip.

Normal strategy according to most pros, as far as I know, is not to go all in there, but rather flat call, and then go all in on the flop (if you think you are still good). This move is known as a stop-n-go. I use it sometimes, but in this case, i really thought he could have any 2 cards(well-any in top 50%), so I didn't want to force myself into a situation on a j 9 7 flop. Whereas if I put him on ak/aq,(tighter player) it makes my decisions easier post flop.

So I end in the money-but barely- in the 30R, something I rarely do, I ussually bust right before the money, or double then and have a decent stack, and make it far.

Meanwhile, sitting 93/303 in PLO Masters.
