Solver output for turn spot.
The solver checks flop at 77% and does check raise 77 on the flop at greater than 90% frequency, so call that 100%.
Interestingly, on the turn, when given the ability to check, b33, or b66 on the turn after check raising and seeing the Ts, the solver checks 100% of range. Solver is check calling with 77 to a b67 at 100% along with all straights, sets, t9s and 97s.
Seems kind of obvious in hindsight. Live and learn I suppose.
