A schmear is when you are laying high point cards (Aces, Tens, and Kings) with the hope that your partner(s) will get the trick.
An example of schmearing:
Partner leads 10♦ (10 points)
Opponent 1 plays Q♣ (3 points)
Opponent 2 plays A♦ (11 points)
Picker plays 8♦ (0 points)
Opponent 3 (out of trump) plays 10♠ (10 points)
This trick was worth 34 points! That's schneider already!
Opponent 1 won the trick as soon as s/he laid down the big Queen. As a result, opponents 2 and 3 both took advantage of the situation and put high-counting cards down. Also note that the picker played the 8♦, a no-counting card.
Good to know Sheepshead rule: WHEN IN DOUBT, SCHMEAR.
