ΔEV (delta EV)
What it means
How much more (or less) one action is worth than a reference action, in bb. In the push/fold charts it is how much the aggressive action gains over folding that hand: if it is positive, the action is better; if it is 0, both are worth the same.
Example
K4o in the SB with 10 bb heads-up: the push's ΔEV = +0.213 bb compared with folding. With 15 bb, the same hand gives −0.111 bb and is folded.
