it's also quite awesome how  dustin  built a triplet puzzle out of the fundamental basic idea. it's always interesting to try to figure how the creator ended up building a certain puzzle or cave in addition to solving the cave itself. i sometimes like that kind of "meta puzzles" even more than solving the actual cave :D

Are there more solutions or am I just "unlucky" :D

i think 341 is the most possible, but who knows, darkstorm. :)

 fellner , 342 apparently is possible (even with non-perfect pushing luck) but i don't think 343 is or i have to drastically change my route :)

you're right,  nesdori ! perfect rock pushes really don't necessary for 342 :)  
at this point i wonder if 343 possible..

 nesdori , one of my approaches for cso caves, which also led to this one here, is to build a cave which i'd like to have and then check if it's solvable!   
  
this cave has a little history:  
\ in my first game, rock fort 1, cave c is based on the idea that ^ must convert one | through a magic wall with 1 frame milling time. back then i gave 0 bonus points without too much thinking.  
\ some day i noted that it's not so difficult to convert two || simultaneousely, which made the bonus value 0 questionable. i implemented this idea in  dustin 's bd1, int 1.  
\ then i tried to figure out if i could even convert three ||| side by side without the help of any other elements. it didn't work, and this ended the story for me for years.  
\ now when i rebuilt the aforementioned int for this site, i came to think about it again. "hmmm, ten years ago, i couldn't convert three ||| side by side, but since then i've learned a lot, so let's try again...still doesn't work... what about cso tricks? hmmmmmmmmmm... aaaaaaaah! i just need a vertical open border to change cso! ha! :d" and the cave was born! :d

so here's the intended solution. i think there should be variations, but the open border should be strictly necessary to solve the cave. in my solution, the open border makes it possible for ^ to escape a | which would otherwise crush him.
