What's your defending range and stealing range here?

[thesharpie]

3 handed 2/4 pokerstars, I have a 51/33 LAG on my right who's been open raising alot on the button, and almost everytime on the SB when he's HU against me. His atsb% is 59%.

On my left is a 20/10 tightie who's straightforward and passive and goes to showdown too much, I daresay he's loosening up a bit. His folded BB to steal is like 70% and 57% HU, although he should be loosening up due to the 3 handedness and the LAG attempting steals every orbit.

What's your defending range against the LAG and your stealing range against the tightie?

Edit: I've defended almost everytime he's raised from the SB so far over ~4 or 5 times, and he's took it down without a showdown everytime, usually me folding the flop. He's probably thinking it's profitable to raise any 2, hell I might against me in his shoes.

Another edit: Stars only takes 50 cents every $20 up to $1 when it's 2-3 handed.
