Well, I think my action would be predicated on my opponents tendencies and based primarily how he reacts to big bets, overbets, all-ins, and how they come about. Does he have yet another buyin to play if he loses? Does he interpret an overshove as a bully mechanism? Is
he tilted to the point of just not caring?
I have no issue with your line whatsoever if these questions meet your standards of adequate fulfillment. I am reminded of
this thread when discussing the art of going all-in/putting somebody else all in, and what it represents/how it is perceived (I realize that the example shown is a much smaller game but the underlying concept can translate).
I will say that I can't see this shove being too far bad if it in fact even is. You have plenty of equity when behind, could very well be ahead, and the pressure of knocking him out of the game may be just the threat you need to actually make the 'bluff' in this 'semi-bluff' work. The fact that the pot and followup bet are not overwhelmingly deep also eases the pain of any miscalculations you may have made when deciphering your best route.
There is always the battle in deciding between finesse and brute force and figuring out which one works best where. The better players choose the right battles...
