As title says. Game is a action heavy live 4 card plo. 2-3 pros usually. The rest more recreational players. Game is usually 9 handed. Unless local whale shows up late, in which case it’s 10 handed. 500-2500. 5/5 blinds with a 10 dollar rock.

Kicker is the rock plays from every position. For example, if the hj wins the hand. The next hand he posts the mandatory ten dollar rock. And the co is first to act preflop. No other straddles occur, regardless of rock position. Rock does count as both the rock and blinds if it happens to be in the sb/bb. I think aria or somewhere in Vegas does a similar thing.

What stratagey adjustments should we be making with out preflop ranges, depending on where the rock is?
