200 bb deep turn ranges -- nl cash

[whaahhahahah]

been playing for half an hour. we've both started playing with about the same level of aggression. he's gotten more aggressive, and i've backed down a bit in the past half hour.

when i've raised the button preflop and checked the flop, he's led the turn 3/4 times. i raised one of the three, and he folded.

3/6 nl
1200 effective

i raise to 18 otb. he calls.

he checks. i check.

turn (36)
7[img]/images/graemlins/spade.gif[/img]
he leads for pot. i raise to 120. he repops to 380 (there will be about a psb on the river).

what range of cards do you expect him to do this with?

what range should i be shoving against a relative unknown?

if you elect to call, what type of river should scare him the most --

a)board pairing
b)diamond
c)9,6, or 4?

and lastly if a, b, or c come and he checks, people think a push is profitable as a bluff?
