Since he bet so small, I don't expect to ever be good with a 9 here so I was thinking about which hands to turn into a bluff here. I really don't see any other hand I get to the river with that blocks a 7 and isn't a str8 or 2p itself. I also don't block any of the FDs and blocking the 9 is probably quite whatever as he probably only has discounted 99 and 96s in his river range, if that. So all in all, doesn't this even make a better bluff candidate than all the missed FDs I might show up here with? I also don't think blocking a T is at all better because while blocking T7s, it also blocks T8s.
