}}

Several exist; one is as follows: '''1. e4 d5 2. Be2 dxe4{{chesspunc|?}} 3. Bb5{{chessAN|#}}''' (see diagram).

At first glance, it might seem that Black can simply interpose a piece between White's bishop and his king to block the check (for example, 3...Bd7 or 3...Nc6 or 3...c6).  But any piece so interposed immediately "disappears" when it transfers to board '''B'''. And Black cannot escape check by fleeing to the opposite board via 3...Kd7, because the move is not a legal move on board '''A'''. Therefore, it is checkmate.

Another form of fool's mate: '''1. e4 d6 2. Bc4 Qxd2? 3. Bb5#'''

And another: '''1. e4 e5 2. Qh5 Nf6? 3. Qxe5#'''
