I'm new to doing any solver work and have never really felt comfortable c-betting OOP so I thought I would start by looking at SB vs. BB SRP on K72r. I started with 1/3 and 3/4 sizing. Unsurprisingly the solver preferred the small sizing, but I was a bit surprised to see it only checking ~22% of the time. QQ and Q9o were checked highest frequency but still weren't pure checks. After getting called the solver is then checking for example ~86% of the time on a 2 turn. Forcing a range bet, the EV was 2.16 vs. 2.15 for the three sizings.
My interpretation is then that our range advantage is significant enough that even with positional disadvantage we can comfortably range bet. We then protect our range by checking very often on many turns. Does this seem right or am I missing something in my interpretation?
