I am neither a good chess player nor a good baseball player, but I believe the concepts of one can guide the other. A young chess player can first be taught some simple combinations that will lead to mate, and then the player practices doing that to opponents to get a feel for exploiting a winning edge when it's there. After that, the player learns to wait until a suitable opportunity presents itself, rather than try to force a winning combination when it's not there. After that, perhaps, the player needs to be taught how to not make mistakes of his own, while playing this waiting game. Then, the player learns to add feints and other tactics to try to provoke error by the opponent. And so on, with varying layers of complexity that I personally never can hope to aspire to. Eventually the player also learns how to play a long tactical game where you build a series of tiny advantages that winds up being decisive. But... and this is the important part... at the heart of chess at even the highest level is the constant threat of unleashing a lethal combination of moves that destroys the opponent seemingly without warning. You never want to lose that spirit of aggressiveness, but conversely you can defeat yourself by trying for a winning combination too soon against a competent opponent. And I think a batter's approach at the plate can benefit from this sequential approach as well, over a period of several seasons in the minors. When all is said and done, the batter needs to know what pitch is the kind he can inflict the most damage with, and wait with varying degrees of patience until it is presented to him. The better the patience, within limits, the less often that patience will need to be exhibited.
