A player at your poker table uses a very unorthodox strategy. You haven't spotted obvious blunders yet, but their style is strange and different from most regs.
Should you treat them like a fish?
Yes! The reason is entropy: there are more ways to play bad poker than good poker. So weird strategy = fishy, until proven otherwise.
Could they be a solver sicko who spent months in the lab perfecting obscure tactics? Sure, maybe. But it's much more likely that they're just freestyling because they don't know what they're doing.
@paulg well if you blow wind into a piece of fabric anchored at two points and the wind is strong enough eventually it detaches
so you get no deaths and no births
