I am also wondering the best strategy to solve this

Hi,

This is one where a strong understanding of the setup is the key to the game. Our initial setup tells us the following

G:
H: R
J: R and at least one of T/S
K: T, S, no R
L:
M: T, S, R

And since we know that there are only three Rs, we know that neither G nor L has an R.

So, G must have one of an S or T, so it must share at least one with K
