NL6 - About hand reading and calling shove

[ettorek]

Villain is a 38/5/3.5 kind of player (but on a small sample).
I was multitabling so I did an evident mistake on the turn not 3-betting: preflop I put my opponent on an hand range like 22+,89s+,TJo+,Ax.
When he lead on the flop I know he got some piece of it so I just flat call: on the turn I flat called and this is a big mistake because I didn't build a pot to make a big raise on the river with a big hand.
Anyway when he shoved on the river I put him too on a made hand: why shove instead of just raise to take the pot?
Thoughts?
