Specifically, what are we check calling? Are we check calling overpairs? Seems like especially if we're in EP and don't have too many suited connectors in our range we are fvcked. I plugged it into CREV for a 567r flop with a 20% RFI and these frequencies are definitely wrong. Need more bluffs and definitely need to check fold less than 80%. With a tighter range in EP it'll be even worse.
This is assuming 1/2. Ignore the preflop garbage.
