The Big four (also known as The "Golden Gate split", "Big ears" or "Grandma's teeth" split) consists of the two pins on either side of the pin deck. It is similar to the 4–7–10 and the 6–7–10, as a common attempt to make the split will consist of sliding the 4 or 6 pin into the remaining two pins on the other side (the ball will take out either the 7 or 10 pin). As with virtually all splits, it is possible to make by bouncing a pin out of the pit. An older nickname for this split is "Double pinochle".
