I am just getting back into chess after a long absence. A friend of mine wanted me to teach him to play, and teaching him, I realized how much I loved the game and missed it.
Anyway, I decided that I would use teaching him as an excuse to improve myself. mainly working up through endgame knowledge, but also tactics heavy games. I used to play French, Ruy Lopez, and QGD, but I was thinking I should immerse myself in some possibly questionably sound gambit openings instead for the next few months at least.
I'm pretty rusty on tactics myself, and although I won't be telling my friend anything about openings beyond "develop your pieces, darn it", I want to force games into sharp, tactics heavy lines that force us both to be extra vigilant. And maybe I should adopt some of the more sound ones for general play as well.
What openings should I play (for each side) to force the game into very sharp, tactical lines, unsound ones are better, and maybe preferred. Ideal would be things that have unsound variations I could play OTB and slightly different variations that give an equal but sharp, tactical game for correspondence.
