Slip, Striker Slip, and Double Touch — fine-control strokes used when coins overlap.
Slip
Pocketing a coin touching a frame by hitting its quarter point.
As shown in figure 16-A, if coin touching any frame is pocketed by hitting on its quarter point, the stroke is called a slip, punch or quarter.
As shown in figure 16-A, if a coin is 5 inches or more away from the base pocket, and then a player should try to pocket it into the opposite pocket.
As shown in figure 16-B and C if a coin is at the base frame of opposite frame then by placing the striker slightly in a cross line with the coin the player should hit at the quarter portion of the coin with medium speed.
As shown in figure l6-D if a coin is near the base pocket then it should be slipped to base pocket. In such a position a rebound should not be tried as such a coin cannot be pocketed so easily by rebound. Sometimes there is a danger of a due if the rebound is not accurate thereby turning the coin from the frame and following the striker into the pocket.
The Striker Slip
Striker slips from one coin to strike and pocket another nearby.
Many times there is a position as shown in Fig. 16-F. One of our coins is stuck up to the frame and the other is away from this coin and also slightly away from the frame.
Normally we shall require two strokes for playing these two coins. If you play the stroke which is shown in Fig. 16-E your striker will slip from the sticking coin and will strike the coin which is little away from the frame and will be pocketed and the coin which is hit first will be removed from that position and will become easy for us. There are rare occasions when these two coins go into the pockets in the same stroke. For playing this stroke you should apply little more force than that applied for the stroke of slip.
Double Touch
Striker touches the coin twice before pocketing — used near side frames.
If the shown in figure 16 is a little away from the frames the striker should be released in such a way that it touches the coin twice and the coin is pocketed, this stroke is called a double touch. Often a player has to play double touch for the coins which are near the side frames. If these coins are more than half an inch away from the side frame only then should this stroke be played. If coins are less than half an inch away from the side frame then a rebound is easier than double touch.
