Answers.Text: The FIDE Rules state that a game is to be declared lost for the playing making TWO illegal moves.
  (FIDE Handbook 7.5 b: "After the action taken under Article 7.5.a, for the first completed illegal move by a player the arbiter shall give two minutes extra time to his opponent; for the second completed illegal move by the same player the arbiter shall declare the game lost by this player. However, the game is drawn if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves.")

Answers.Body: <p>The player of the white pieces has made an illegal move. Touch-move applies so he must take back his illegal move and make a legal move. If it is possible to make a legal move with the piece he touched then he must make a legal move with the touched piece. If there are no legal moves with the piece he touched then he may make any legal move. This is important because often making a legal move with the touched piece loses the game immediately.</p>

Answers.Text: Touch move applies only if they are playing with touch move. If they're just starting to learn chess, they are probably playing casual games, not tournament ones. Also, if they are playing with touch-move, then if a piece was captured with a piece that cannot be legally moved, and the piece can be captured with another piece, then the player must do so.

  It's not technically a check since Black wasn't making a move to check White's king. White made an *illegal move* that placed his King under attack.
  
  Black should mention that White made an illegal move, getting White to take the move back and play something else. If you're playing in a tournament, you could call the arbiter over and say White made an illegal move (often 3 illegal moves = forfeit).
