Many thanks for all of the comments on this.
I chose not to say whether it was me in the SB or the BB, to allow for some balanced comments, and it"s not as straight forward as I first thought, and when next in the situation I"ll certainly have a better thought process with which to make the decision.
So, anyway, I was the one shoving from the BB, with the thought that the SB just wouldn"t be able to find a call with much more than AA and KK. Partly to defend my blind and also give more of an aggro table image. I was very surprised to see him call with the AK. If roles were reversed, I just don"t see how I would make that call, but as others have explained, it"s not the worst call in the world.
Interesting stuff. I managed to totally butcher the situation basically. GG me.
