Umm how many chips do you have?

Second, is the 4.25x raise standard for this guy? That has to mean something, and he just put in like almost 25% of his stack, so I'm really not sure he's folding 78% of his raising range, that would be pretty odd given the raise size. The tough part about these EV calculations is getting the ranges right, the math is pretty simple. Decimal points in front of those percents would help...I'm not saying the ranges are right, but it would look like

.78*9700+.22*(.31*25000-.69*22000)

You don't win 47000 when you win the hand, but only lose 22000 when you lose. Finally, this is a shove with ATC if he's folding anything near that much of his range...unfortunately he's not folding that often. Actually, considering he raised to 6800, and you only have 22000, he's pretty much never folding unless he's an idiot.
