I simulated a hand played between these two gents and im noticing on Ts8s4d in a SRP IP checks back Jx, 9x, and 7x flush draws at a decent frequency even assuming a small cbet strategy. These are hands im usually autocbetting because we block OOPs continues/XRs and turn more equity frequently. But im wondering why solver Xs back these particular FDs. Is it so we have turn bluff raises when we turn a straight draw to go with our flush draw? Is it because we're blocking a lot of the hands that OOP would auto probe turn so we realize equity more easily with these hands?
