The slip or slide chasse is a very basic movement, but like all basic movements it should be practiced regularly and correctly to gain the maximum proficiency and speed.
 
 Firstly, we will take the left forward chasse. Starting on a left forward outside edge with your left hip, shoulder and arm in the lead and your hips at approximately 45 degrees to your skate and facing to the outside of the circle. You should have bent both knees before pushing onto this edge, so that the LFO starts on a bent knee. Your head should be looking forward along the circle over your left shoulder. Then you slowly rise on your skating knee drawing your free in towards your skating foot at exactly the same time so that when you feet touch both legs are straight but not stiff. Your left foot should still be half a foot in the lead as your hips are still off-set. You then simply change feet. There is no need to bend both feet before you push as you do not push on this movement. It is then up to you whether you bend the new skating knee on the RFI in order to extend your free leg (this is the most usual method) or simple lift your left leg forward. The method you use really depends on the character of the dance that you use the step in and the effect you wish to create. It is then possible to create extra speed by pulling yourself forward towards your free foot in order to bring your feet back together to start the next step. Again your left foot should remain half a step ahead and your left hip should also stay in the lead, this action I call 'drawing' the skate and every time that you raise on your skating knee it should be possible to gain speed by progressing your body weight forward in the direction that you are travelling. This step is completed by once again bending both knees before pushing to restart the step. It is particularly important in this exercise, that you make every effort to ensure that you achieve as much speed from the 'draw' as possible.
 
 You obviously should also practice this on the right side, this time with you right hip and shoulder in the lead throughout the exercise.
 
 This movement can also be done backwards, starting with your hips and shoulders facing inside of the circle you intend to skate. If you start on the RBO your right hip should be back and you right foot should be half a step behind the left. Again having bent both knees before you push, you start on a bent skating knee. Again slowly rise the draw the feet together still keeping the right foot half a step behind, simply change feet to be on a LBI and then either bend the new skating knee to take the free foot away behind or simply lift the free foot up without knee action. Again the first method is the most common and useful method. To get the feet back together to complete the step again you should draw yourself back towards your free foot once more again speed as you draw, as the feet come together the right foot should still be half a foot behind the left, you then bend both knee to repeat the step. Once more you should train this on both feet, but simply keeping you left hip and shoulder in the lead on the other side.
 
 I hope that some of this information will help you to improve your slide chasses.
