Obviously the Turn is where this hand gets interesting, but the preflop pay needs to be addressed. One of the fundamental concepts of PLO is to 'bet your hand.' Bet your hand!

Don't mistake this advice for re-potting with AAxx when you have a lot of money left behind and will be giving your hand away... but do not limp into pots with strong hands. Even if you only raise 2bb or 2.5bb from early position, that's better than limping in. If you like your hand... build the pot, as long as you aren't revealing your hand.

On the Turn, I think you can check-call to induce bluffs from certain opponents, but betting to charge a flush draw is reasonable as well. Without reads on your opponents or these games, it's hard to make a clear recommendation either way.

When in doubt, I lean towards betting.
