That's true.
It's good learning watching how players punish slack play in every opening
and you will soon see some of the tactical ideas appearing in your games.
I use to know a site were you could get the games but no notes.
(Infact Chernev's notes are very light, just amusing intro's and a comment
here and there.)
Like Paul I often grab the book at random and skip through a few games.
The plan being to play over a few catoons before hitting the hay.
Often a bad idea as I'm still there 2 hours later pulling some game
to pieces especially of I see a counter trap.
Every Black win can be produced by White a tempo down I try to
created the game with a White win losing a tempo.
Or experiment with daftness.
A basic example.
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bc4 {now if 4...Nf6 White can go mainline with the Two Knights where Black 0-0-0 is there any trick somewhere in there where a6 is needed for a piece, are b2-b4-b5 shots on v a weakened castled position.Stuff like that}
