Backup Strats

Unless otherwise noted, the following backup strats were made by Poochy.EXE in preparation for SGDQ2015.

Stage 3: Misdrop O

If you fail to shift the O piece under the overhang, or accidentally bounce it back:

You'll need to waste 2 pieces on the left side before the T and I come. This will put you 2 pieces behind route going into Stage 4, proceed with the first catch-up strat below.

Stage 4: Misdrop S

If that S slips to the right:

You'll need to waste a piece before the J comes. Stage 8 becomes a 2-skip, and you're back on route.

Stage 10 becomes a 5-skip.

Stage 17: Catch-Up or Wasted Piece

If you waste a piece or two building up the left or center sections, or just came into the stage a couple pieces behind, the second I you need at the end will come before you can use it, and you'll still have the first I in the hold box. However, you can use the first I early, since there's just enough room to maneuver it in:

You'll need to waste an I before the last S. Stage 18 becomes an 8-skip.

In case you accidentally shift the first S to the right before locking it:

Stage 18 Catch-Up

If something goes wrong on Stage 17, often you'll need an extra I piece at the end to fill in column 10. Unfortunately, you also need that I piece in the hold box at the start of Stage 18. This backup strat allows you to cope without it, substituting in the I piece you'd normally skip in stage 19 at the end:

EX5: Accidental Hold

Use this if you accidentally hold the first L or S (e.g. you accidentally press hold for IHS before locking down the S) and are forced to use the T from the hold box prematurely.
