Omaha 8 starting hands heads-up, and an overpair on a low flop
In Omaha 8 you get four cards and must use exactly two with three from the board, for high and for low separately; a low needs five different cards 8 or lower. Heads-up, the button acts first before the flop and the big blind defends. The pages here are the solver's strategy for every starting hand on the button and in the big blind, four hands that come up in questions (A-2-3-4 double-suited, a bare A-2, A-A-2-3, high-only Aces), and one flop spot: an overpair with no low on a low flop.
