The Head Pin or the Number One Pin
split
Ira J Young invented the split pin in 1912.
It's a "split" or "split-pin" situation.
Knocking down all the remaining pins after the second ball in tenpin bowling is termed as a spare.
The one closest to you is the head pin, or 1 pin. The rest of the pins are numbered from left to right on each row: the second row has the 2 and 3, third has 4, 5 and 6, and the fourth row has 7, 8, 9 and 10.
The 8086 comes in a 40 pin package with 2 ground pins and one power pin; the remaining 37 signal pins every single one is important.
A split is an arrangement where there are separate standing pins, or groups of pins, with pins between them having been knocked down by the first ball rolled. The most extreme separation would exist when only the 7 pin (leftmost on rear row) and the 10 pin (rightmost on rear row) are left standing, e.g. a 7-10 split. There may be more than one way to knock down all of the remaining pins to complete a "spare" with the second ball. To do so is to "make the split." According to rule 2h of the United States Bowling Congress (USBC): A split is a setup of pins left standing after the first delivery, provided the head pin is down and at least one other pin is down: 1. Between two or more standing pins; e.g., 7-9 or 3-10. 2. Immediately ahead of two or more standing pins; e.g., 5-6.
Barmaid is when any one pin hidden behind another. This is also referred to as a sleeper.
The top of the pin is called the head of the pin.
An oar pin is also called a rowlock pin or a thole.
