I remember reading a thread on 2+2 where someone (El Diablo) was experimenting calling every CO and BTN raise from the blinds and c/r-ing every A high flop.

Conclusion was that the play was very likely +EV. Someone else (samoleus) advocated doing it on K high and Q high flops. I haven't done much detailed thinking on it myself yet, it's at least interesting though.

Well...I don't know what that really adds to this thread....but it just crossed my mind
