It can be an advantage to lead to a trick, because the player who leads controls the suit that is led and which others must follow; the leading player playing a suit of which he has many, decreases the chance that anyone else would be able to follow suit; while conversely playing a suit of which he has few, allows him to rid his hand of that suit (known as "voiding" the suit), freeing him from the restriction to follow suit when that suit is led by another player. On the other hand, it can also be advantageous to be the final player who plays to the trick, because at that point one has full information about the other cards played to the trick; the last player to a trick can play a card just slightly higher or lower than the current winning card, guaranteeing they will win or lose it by the minimum amount necessary, saving more valuable high or low value cards for situations where they must guarantee that a card played early to a trick will win or lose.
