im short stack, but im not desperate. i dont mind the fold here, but i chose to tank it. big stack has been showing proper aggression, and as such i can put him on nothing through AK, a steal is not out of the question on my read.

i decided to take the semi-resteal over the fold. My table image was quite aggressive, but id been showing strong hands. the fact he had a big ace meant he would always call, but thats neither here nor there.

was it the right line?
