Calling Pre-flop? Strongly Consider 3-Betting Instead (NLTRN Theory)

[xSCWx]

Is this only for 10/20 blinds?

Say we are playing in 15/30 blinds:

Villain raises to 90
Hero reraises to 270 with A[img]/images/graemlins/spade.gif[/img]T[img]/images/graemlins/heart.gif[/img]
Villain calls

Flop: 7[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/heart.gif[/img]9[img]/images/graemlins/diamond.gif[/img]

Villain checks
Hero cbets 400
Villain shoves

If we call we are probably significantly behind. If we fold we are dumping close to half our chips.

Am I missing something?
