4.3
Except as provided in Article 4.2, if the player having the move deliberately touches on the chessboard......[a description of the touch-move rule follows]
which seems to indicate that only intentional touches are sanctioned, as we (ma and plutonia) are claiming.
Yes, it's standard practice that only intentional touches are sanctioned.
It's even mentioned in the wikipedia that accidentelly touching a piece does not count ( e.g. brushing against it while reaching for another piece) and every competition in the planet follows this rule.
That article that was linked earlier is just wrong.
Adjusting a piece is a different thing, because you intentionally reach for a piece. That's why you have to say it first, because your hand clearly goes to grab that particular piece. But if you accidentally touch a piece while reaching for another one, how could you have said it in advance? You didn't know it was going to happen!
The USCF rules specifically mention "accidental" touch as a not activitating the touch-move rule. A sleeve brushing a king while reaching for another piece is a common occurance. USCF and FIDE often differ. USCF rules are far more verbose.
