I like gaybetting this spot like $8 and shoving over a raise, or if flatted crai any turn.

oh didn't see you are a bit deep. I'd bet/shove flop, prob cc all turns and be psychic on the river, almost certainlt c/f.

Wait, we have a pair of 7s against someone who has 15% PFR and calls 9% to a 3bet, why is your plan so aggressive?
I seriously don't get it at all and need to look at 3bet pots some more, would you mind explaining why you'd do all those things?

I'd bet/shove because we can reasonably expect 9 outs if called and we would need only a very small amount of fold equity, along with the money in the middle, to make it profitable. Obviously I think it's much better only 100bb deep, but still. I'd c/c the turn to pick off floats, because I find that when people flat a 3bet in position they float like hell, just from experience. I'd c/r the turn with 100bb stacks just because I would find a c/c very awkward to play on the river, and he is likely to have a good draw by the turn, and it's a nightmare to know what kind of river situation we are in.

This is all in the context that I have a pretty wild image, but your stats look to be aggressive enough at this table.
