[Shattered]

Without reads I shove here all day. You need a read to check/call here, but I think that's optimal against a large portion of players. If villain is aggro and bad I like c/c because he shoves all flush draws here; medium PPs are a small part of an aggrodonk's range at this point, so you're just hoping to get value out of 56 if you shove (which you may not).
However, for your typical, readless unknown, not shoving allows him to check behind a huge part of his range that he would call a shove with and is leaving value on the table.
