Any new format for play ing chess inevitably creates new tricks — and new blunders.

This is shown by the souped-up Internet game, appropriately called “bullet chess,” in which you’re allowed only one minute for all your moves.

One of the powerful “bullet” techniques is a “pre-move”: While your opponent is thinking about his move, you can input your reply to it.

Once your opponent plays his move, your pre-move is made instantly. This can save valuable seconds, as US Champion Hikaru Nakamura describes in his first book, “Bullet Chess.”

For example, if you’re fast with your fingers, after 1 e4 c5 2 Nf3 d6 3 d4 you can input 4 Nxd4 before your opponent can capture on d4. If he makes another third move, 4 Nxd4 will be illegal, and nothing is lost.

But as Nakamura and co-author Bruce Harper point out, pre-moves are risky. After 1 e4 c6 2 d4 Qc7?! Black is hoping that White makes a common-sense reply such as 3 Nc3 — then adds the natural 4 Nf3 as a pre-move.

But that would be a blunder if Black replies 3 . . . Qxh2??!.

White would love to capture the queen. But he is committed to 4 Nf3??, and would lose to 4 . . . Qxh1!.
