contemplating a bluff, semi-deep

[terp]

villain is 22/18/2.5 over a very large mined/played sample. 3bets me a LOT in position without a ton of regard to opening position/donks behind in the blinds who could coldcall/etc. i am not positive about the last statement, but his frequencies suggest it. i try to return the favor a bit but am generally tamer pre and prefer to play postflop.

i run at 23/20/5 and he should have me at around that.

this is our first multistreet confrontation in a 3bet pot against him. we have not felted yet in a 3b pot. he has never seen me get caught making a huge bluff or get away with what is probably a bluff.

so:
1) if he checks, how much?
2) what range of river bet sizes may i shove over?
