A Sextuple Leave is shown opposite.  Assume the opponent (Black and Blue) miss your ball (try to leave only one open) near third corner.

1-back Peel

Hit opponent and stop-shot into the lawn (say past hoop 3) (A), getting a rush to hoop 2 (some people may prefer south boundary) (B). 

Rush peelee to hoop 2 and take off to pioneer at hoop 1 (I usually try to rush into peeling position at 1-back and peel going to pioneer at 1). Make hoop 1 and rush to ball near 3 (C). Position hoop 3 pioneer at hoop 3 or slightly west, getting rush on other ball to hoop 2 (D). Croquet escape ball to 3-4 yards southeast of hoop 2 (E), obtaining rush on peelee. Approach hoop 2 sending peelee in front of 1-back (F). 

Run 2 and hit peelee. Peel 1-back, sending peelee down to 2-back and obtaining northwards rush on escape ball. Rush to comfortable position (G) to be able to send to hoop 4 (H)(or slightly west) getting a rush to hoop 3 on pioneer. 

Make 3 and rush so that you can send out an escape ball (see ** below), whilst obtaining rush on peelee to 2-back (I)

** If you have peeled 1-back to close to 2-back and are confident of rushing peelee in front of 2-back and at least jawsing going to your hoop 4 pioneer, you can send your escape ball 4 yards east of 2-back (but not blocking path to hoop 4 pioneer). If you are not confident of jawsing before hoop 4 (this is more likely), then send your escape ball to a position where you will get a good rush to hoop 5 if you play a stop shot peel from 2 feet (J).

2-back Peel

Assuming you are not able to peel before 4, take off from peelee leaving it close to 2-back (K), going to your hoop 4 pioneer. Make hoop 4 and rush back to near corner 1 (L), in a position where you can send a pioneer to hoop 6 (not beyond), obtaining a rush on peelee to peeling position (M). Peel 2-back obtaining a rush on your escape ball to hoop 5 (N)

3-back Peel

Make hoop 5 and get a rush to corner 1 (O)(most places on A-baulk are ok). Send pioneer towards 1-back (I prefer it 2-3 yards south), getting a rush on peelee to 3-back. Rush peelee to 3-back (P) and take off to hoop 6 (try peel if you play good rush). If rushing peelee to 3-back is not possible, you will have to croquet peelee to 3-back going to hoop 6 pioneer.

Make hoop 6 and rush to corner 4 or north of corner 4 (Q). Croquet ball to 2-back (2 yards north-east is handy), obtaining rush on peelee to 3-back (R). Peel 3-back to 4-back, going to your 1-back pioneer (practice) (S).

4-back Peel

Make 1-back, obtaining eastwards rush (T). You want to end up with the peelee in front of 4-back with your escape ball a couple of feet to the side. The exact combination of strokes to achieve this will depend upon how far you have peeled 3-back and what shots you are good at (U). Take off from peelee, leaving it near to 4-back (1 inch in front of the hoop is handy), going to your pioneer at 2-back. 

Make 2-back obtaining rush to 4-back (V). Send escape ball 4 yards east of penult (personal preference will count here), getting rush on peelee to 4-back. Peel 4-back obtaining rush to 3-back (W).

Penult Peel

Make 3-back obtaining rush to 3rd corner or vicinity (X). Send ball to 2 yards south of penult and off the line of penult and rover, getting rush on peelee to penult (Y). Rush in front of penult and peel obtaining rush to 4-back (Z). Finish with single peel. If you don't rush in front of penult, finish with straight double. Sorry, I can't tell you how to do a straight double, because if Mulliner were to find out, he'd be much more difficult to beat, and he's the only player I can beat nowadays!
