When using English (side spin) in pool, many factors can throw your shot off course. The main culprits are squirt (cue ball deflection), swerve (the curve in the cue ball’s path), and throw (the object ball’s deviation). Mastering these effects is essential for any player aiming to improve precision, especially when applying spin for position play or kick shots.

This blog will break down these concepts, explain how they interact, and offer practical solutions for compensating during gameplay.

Introduction: Why Understanding Squirt, Swerve, and Throw Is Crucial

Using spin in pool introduces complexities such as squirt, swerve, and throw, which can alter the cue ball’s path and the object ball’s trajectory. Understanding these effects and learning how to compensate for them can significantly enhance your accuracy and overall performance.

What Is Cue Ball Deflection (Squirt)?

Squirt occurs when the cue ball is hit off-center with English. Instead of moving straight toward the object ball, the cue ball is deflected slightly in the opposite direction of the applied spin:

• With right English, the cue ball squirts left.
• With left English, the cue ball squirts right.

What Is Swerve?

Swerve happens when the cue ball curves after being hit with English, especially when the cue stick is elevated. The effect becomes more pronounced on slower shots, where the cue ball has more time to curve before reaching the object ball.

What Is Throw?

Throw occurs when the cue ball hits the object ball at an angle, causing the object ball to deviate slightly offline. The direction of throw depends on the type of English applied:

• Right English throws the object ball left.
• Left English throws the object ball right.

How to Compensate for Squirt, Swerve, and Throw

1. Use a Low-Deflection Shaft

Low-deflection shafts reduce squirt by flexing more during off-center hits, making aiming adjustments more predictable.

2. Adjust for Squirt Using the Pivot Method

The pivot method involves slight aim adjustments to compensate for squirt:

• With right English, pivot slightly left.
• With left English, pivot slightly right.

Practice Drills for Managing Squirt, Swerve, and Throw

Drill 1: Squirt Awareness Drill

Set up a straight shot and apply different amounts of English. Practice adjusting your aim using the pivot method until you can consistently pocket the shot.

Drill 2: Swerve and Elevation Drill

Practice shots with slight cue elevation, noting how swerve changes with different levels of spin and speed.

Final Thoughts

Mastering squirt, swerve, and throw is critical for improving accuracy when using English in pool. By understanding how these effects interact and learning to compensate through practice, you can significantly enhance your gameplay. Whether it’s using a low-deflection shaft or adjusting aim with the pivot method, consistent practice will help you develop the necessary skills to control spin and aim with precision.
