BB was a reg. Is this a good spot for triple barreling?
I have some equity with the gutshot.
On the turn he has to fold most Qx, flushdraws, his double ch/calling range will be quite narrow, mostly mid-Ax, like AJ/AT (AQ is less combos, and AK would have probably 3bet preflop).
On the river even with AJ all he beats is a triple barrel bluff. Flushdraw missed, but I can easily have AK/AQ, even something like Q:dX:d, and he doesnt know my barreling tendencies.
