I used to buy in for close to the minimum because people were a lot more apt to call me when I shoved. I thought it was a great strategy, and I was winning money with it.
Then I saw a tutorial video that said something along the lines of, "if you have an advantage at the table, don't you want as many chips as possible so you can exploit that advantage?" The more chips you have, the more you can win. That made a lot of sense to me, so I started buying in for more.
I drew a green line to show when I started buying in for whatever the big stack at the table had. (Now I just do the max buy-in)
So yeah, short stacking was profitable and minimized loss, but I had no idea what I was missing out on.
Now, I never moved up in limits. I would just buy in, double-up, and quit.
