CO straddles, "SB" and "BB" flat, which is uncharacteristic of those two regs, as they tend to 3b/fold.
Hero's open range here is a smidge lighter than a standard CO opening range. What should Hero's multiway cbet strat be? Currently cbet's a bit merged to overpairs, various overcards, some trips and boats, weak draws, with my checking range being polarized to some trips, strong draws, and utter junk.
