The idea “telecasting” in pretty much any game or sport (baseball, futbol, poker, chess—what have you) has probably as its closest synonym the
term “representation.” In poker, since a large portion of the game is played
without being able to see an opponent’s cards, a player must base their opponent’s
hand ranges off of how a player telecasts their strength which could be an
endless amount of variables: bet size, bet size in relation to position, the way someone bets, body language (the way
someone sits), table history (has the person been playing hand after hand or
have they been waiting patiently). In poker, telecasting can frequently lead to
reverse psychology scenarios, to double-reverse psychology scenarios, and
believe it or not, possibly triple-reverse psychology scenarios. As an example,
if someone is on a hot streak at a table, and they are appearing to play every
hand—if such person gets dealt a very good hand, it’s likely advantageous for
such person to go ahead and continue playing aggressively (maybe even extra
aggressively) because it fits their already established table image. In this
instance, they would be telecasting “loose” play even though they are actually
playing some version of the expected norm.
In baseball, a baserunner might telecast his intention to
steal to the pitcher by taking few extra steps in his leadoff stance. A pitcher might telecast a certain pitch by
shaking his head too many times at the catcher. In tennis, possibly the way
someone serves provides a clue as to where the ball might be going. In soccer,
the most notable development I’ve seen in penalty kicks is the players doing a giant stutter step before they kick the ball—therefore flipping the telecasting in their favor by allowing them to see which way to goalie might be diving.
