Ax, where x might equal 7,8, maybe 9 - folding with 10-13or so bb's, 6handed is fine.

Here, you have enough chips to make a standard 2.5-3x raise - folding to a push from a substantial stack.

Ah, but what about the shortie blinds?

If you raised it to t375, I think you still get away from a SB push. With shorter yet BB behind, I think it's reasonable to put him on a range making folding proper, despite getting....better than 3:1? Meh, close.

BB of course we'd call.

That having been said, open folding this is fine too IMO. Much would have to depend on the table dynamics to this point.
