Sneak Preview
Sneak Preview is one of the new possible maps for Sokoban Level 2 in Hack'EM. It has 12 boulders and 10 holes, but only 11 are accessible in a given pass, leaving 1 spare boulder.
The puzzle layout is nearly identical to Reading Rooms rotated 90°.

Open a path so you can clear the first two boulders:
---- A ll
-----------..| I uuuu uuu
|..K.^^^^^^..| K rr*
|.--.-------^| I urr*
--......|...|^|
|.......+.L.|^|

The next boulder can be taken from either 3x3 chamber, with the doors functioning like the prize doors on the top floor do in Hack'EM and some other variants: once you open one door, the other will seal. If you want to look for any items within either chamber before then, a means of object detection (such as the potion of object detection or the detect treasure spell) is recommended. The right chamber has a set of iron bars that cannot be destroyed, but can be crossed by phasing, or by polyself into a form that has phasing or else can slip between the bars.
Left chamber
This set of moves assumes that you opened the chamber containing boulder J:
