Hello bro, okay with you? I hope that Yes.
Responding to your question, show the letters in a large fold can be a strategy very efficient against short stack.
Suppose that the villain in the position of Button give a raise enough to commit my stack, I in the position of SB solve fold showing my two letters AQs to opponents. In another opportunity with 9Ts decide to raise against a short stack in BB, the probability of your opponent foldar is very large due to image that you shows on the table.
GL my friend.
