I have been adopting the Scotch opening recently with some moderate success. I would like to know whose games should I look at to have a good understanding. I see that Nakamura and Kasparov deploy Scotch reasonably often. Apart from him, I was surprised to see that Tal used Scotch in only 3 games and Fischer never. I was under the impression that Scotch gives rise to dynamic active position and hence my surprise.
I religiously play scotch in e4/e5 games. Sergei Rublevsky is the star I follow.
Magnus Carlsen has some games as White you might look for. GM Parimarjan Negi authored a DVD on the Scotch and has himself played it on many occasions.
Fischer loved the Ruy Lopez so didn't have much need for the Scotch, and in general fashion has favored the Ruy Lopez. Then Kasparov resurrected the Scotch (he even had an affair with the Evan's Gambit) and it saw new light.
I generally prefer GM Negi Parimarjan, who is the master of the Scotch Opening and, as mentioned above, he has created a DVD series.
He has played Scotch lots of times.
