Hello again,

W: Kh1, pawn a6

B:Kg7 ,Rb2

Black has just plyed Rb1+. white didnot recognize the move and touched pawn at a6,and then the opponent has just called the arbiter.what should arbiter do?

Is the player allowed to take his move back before he punch the clock(because he's in check position?)

sorry 4 my bad english but i hope you understand me

thx

Hi hmddemir--nobody can force a player to make an illegal move, including the tournament arbiter.  The pawn cannot be used to block the check, so the arbiter will tell white to move his king and ignore the touch-move rule.  Otherwise the game would continue with white in check from the rook, and since black is aware of that, he would simply take the king or raise the same issue on the next turn.  It does not make sense to allow this to happen.

The touched piece must move rule is just a rule. It cannot be applied in every situation. 
- If the piece that you touch cannot make a legal move than of course you can make another move. Otherwise it would be impossible to continue the game.

Well, tournament arbitration is really not about "punishment."  Its goal is to keep the game fair and playable for both sides.  White didn't do anything wrong on purpose; he simply failed to notice that his king was in check.  If black didn't notice this either, then both sides might make a few illegal moves before somebody realized what had happened.  At that point the arbiter could attempt to step backwards in the game to the time that it was still a legal position, or he might ask white to move his king out of check on that turn so the game can proceed normally.  This happens among very new players sometimes.  In the situation you described, there's no need to punish unless it's somehow demonstrated that white was knowingly trying to cheat.  If he made a mistake and simply did not notice he was in check, then the goal of the arbitration is to get back to a legal and fair position which may have happened anyhow.
