I wasn't sure while playing it, but I felt its close to call his raise OTT. When analyzed it post session, it really seems like I gotta have at least 26% equity to call to break even and I have ~25.56% against his set(s). So I guess I can call, especially if he will check/call or bet/call my bet (or raise) OTR if I do hit. BTW: Maybe you will laugh at me, but his timing of his check and timing of his raise OTT really felt like SET to me ...
