Trying to work it in more . I 3bet light, but nowhere near enough.

Maybe not enough to be seen as a maniac dev, but I think I 3-bet my BB and cbet the flop, raised my SB (think BB folded) then 3-bet my button and now cbet a board not likely to hit me, he's probably either going to think I'm a bit of a maniac, or think I'm positionally aware and at least have a fair chance of bluffing here. As you say, once I get to this spot I think its the only way to play, and if I get called I have 8 outs and possibly 11.

I think I only have about 4-5% 3bet on average, and I only 3-bet QQ+,AK for value, so around 2-3% bluff range. Thats way too low and hardly going to inspire fear or silliness in my opponents. So generally speaking trying to increase my aggression overall in the right spots against the right opponents
