I only have 6hands on all villains. Intending to call SB and fold to others, is this ok?

i think 15 BB's is the cutoff between open shove or min raise...so i think its fine

If you are worried about the sb possibly folding then I would bet 2.1x to make it just slightly less easy for the bb to peel a flop on you. You don't want to be contested here if possible so make small adjustments that improve that chance. Obviously fold to both 14bb stacks if they jam and pick off the sb.

Also, jamming isn't bad. There is a <1bb stack at the table and you cover all stacks behind. Putting pressure here with K9o is very profitable. Opening is going to run a little less variance but you will never r/f to a worse hand if you just jam :P

This is a shove. I'm shoving way wider than this. something like 22+ A2+ K7o+ K5s+ QTo+ Q8s+ JTo
