Like a few other situations in limit poker, river play in omaha when trips on the board (and no low possible, if o8) should be near automatic because of the few possible hands.
Assuming heads-up at a 50% flop o8 table with fairly straightforward players, what hands in the lead do you bet, check/call, check/fold with? (This seems analogous to the clarkmeister.) The check/raise option seems dependant on the play on earlier streets.
If in position and checked to, what is bet/call, bet/fold, check? If in position and bet into, raise/fold/call?
I know this is situation doesn't come up that often, but I've seen it a few times today and it seems simple enough to resolve to be useful.
