As a chess player -and former city of syracuse champ - I don't agree. Doak, I love ya, but you're dead wrong and I challenge you to a chess match.
Chess is BOTH strategy AND tactics. Both fit hand in glove. http://www.chessinvasion.com/strategy-vs-tactic.html
Example: Strategy = When I'm white I like to play the Ruy Lopez, but not the Sicilian Defense. But once you play e4, things are out of your hands. Your opponent has the ability to play c5 and you're in the Sicilian.
Now the Sicilian is monumentally complicated. You can spend your whole life trying to find your way through that maze (never get outta this maze...never get outta this maze...).
So my strategy was trim down the number of Sicilian defense openings significantly...so anytime someone plays c5 back at me I play d4...and move into the Smith-Morra Gambit.
Suddenly a million lines are down to three...the decline, and 2 lines of the accepted...whether they take after I play c3 or not.
Other strategy issues: attack king side or queen side? Get into a specific end-game like rook and pawn vs something else?
Tactics are the way you execute the strategy...like Kyle said...x-ray attacks, forks, pins, etc.
As to golf, you can have all the gadgets in the world, but the execution is what matters. If you are tempted into the shot that's too much for you or you put a poor swing on the ball, all the info in the world can't help you.
