Spades are trumps. Dummy has J4 of spades. Declarer leads a heart from
hand, which LHO ruffs with the S5. Declarer says, "ruff". Does he play
the SJ or the S4?
The argument for overruffing is that "ruff" is equivalent to "win" (as
if he had led the S2 from hand). The argument for underruffing is that
he didn't notice the play; if he had led towards an AQ in dummy and
said, "queen", the queen would be played even if LHO had played the king.
