Ok, late at night and my mind is wandering. We know about edges in ICM and exploitative and optimal play. Exploitative play is basically about adapting to your opponent's tendencies and trying to make the most money out of them. Optimal play usually refers to not being exploited.

I'm just wandering if there is an optimal exploitative play. The wording is a bit unclear here.

Let's say we are dealt KQ in the BTN, we shove. If villain calls with 50% it's +0 EV, if villain calls with 25% it's +0.4 EV, if villain calls with 10% it's +1.0 EV. The numbers aren't really that important, but it seems to me like there is some magic % we should be shoving, which isn't necessarily where EV > 0. I mean that's generally the common wisdom; seize any +EV edge. However if we take a +0 EV edge we are just increasing our variance and could potentially be knocked out in some hands.

The point is, should we be shoving every +EV edge? So in this example we might shove 35%, if we believed we shouldn't shove every +EV edge.
