You could make a case for calling as you keep his range wide enough in case he is so much of a maniac that he is bluffing, or that he has top pair. However, I like pushing because even though it obviously folds out air and possibly one pair, the trade off is getting max value now vs decent holdings as there are some nasty river cards. If the board comes out a 5,9, T or even a heart you almost have to call a shove but its gross.
