I will higlight a more "appropriate" game/sport (?)
In chess if you touch the piece, you move the piece ~ it's a piece of etiquette that the game is founded on.
Here the card whether it was faced or not was removed from the hand and "should" (I know the difference between what the law is and not what I want it to be, bluejak
) be played ~ that'll teach delclarer to pay attention
Equally, when a player breaks etiquette and draws a card from their hand before their turn to play the TD should be called immediately and if the card cannot be played legally then a revoke should be established
or if that offends your sensibilities the draw card should be immediately faced as a major penalty card,
All the best,
