as i understand crossing the boulders to the right is possible due to open border? i must confess that i'm not as good with understanding this cso tricks :-(

 Piter , INDEED THE OPEN BORDER MAKES IT POSSIBLE FOR ^ TO CROSS THE |||  from left to right, but only via the top row.   
  
if ^ tries to di it, he will always come into a situation like this:  
  
Β  
.  
.  
Β  
^  
.  
Β  
.  
.  
Β  
  
normally, the Β above ^ is scanned before ^, meaning that the Β crushes ^ before he can escape.  
  
but if open borders are involved and if ^ is in the top row, the situation (technically) looks like this:  
^  
.  
.  
Β  
.  
.  
Β  
.  
.  
Β  
.  
.  
Β  
  
now the dangerous Β is in the very bottom row of the cave, so this time, ^ is scanned first! so ^ escapes in time before the Β "notices" him.

the three-seconds-faster solutions puzzle me, actually :d

 dustin  thanks for explanation. this is probably due to scan order.

INDEED  Piter  :D ACTUALLY "CSO" MEANS "CAVE SCANNING ORDER". IF I RECALL CORRECTLY, IT WAS  shredder  WHO USED THE ABBREVIATION "CSO" FIRST, AFTER I HAD UPLOADED THE FIRST FEW CAVES OF THIS SERIES :)  
  
more cso effects which are used in this cave:  
\ the fact that ^ can move through the falling ||| from right to left (even without using open border)  
\ the fact that Π can be pushed over empty space from left to right (but not vice versa).
