Flatting range 12-15BB deep vs ~ 70% opener

Preflop decision.

1. Should I have a flatting range @ 12-15BB deep vs a min raise?

Or does an exploitative 3b jamming range have better expectation in your experience? 

 

Villain was opening about 70% from the button > 12BB and I had seen him limp in 6-8BB region. 

So far he has cbet every time (3/3) and barrelled the turn the one time the flop went c/c. 

 

I think I need to be fighting back vs this type of player so I don't get run over by: 

- expanding my 3b range for both value and add in some bluffs

- expanding my flop c/r bluffing range

 

Flop decision. 

2. Do you think a donk or a NAI c/r is more effective on this board vs a wide opener? 

(gameflow wise villain has not seen me donk)

against a 70% opener 97o is a

against a 70% opener 97o is a profitable jam also if you´re being called rather loosely. if villain doesn´t call significantly wider than 30%, your push is fine.
 
against a frequent opener i´d either push or fold that hand, depending on how wide i expect him to call.
 
as played i prefer the check raise to a donk. you´ll get floated a lot and you´ll also get called by every eight and 3x that can improve. you´ll also get called down lighter if you donk than if you check raise. i think check raising a GS is a good decision. it´s not good enough to call and a donk will often just leave you guessing about villain´s strength.

Yeah you should defs have

Yeah you should defs have a flatting range @ 12-15BB deep vs a min raise.  I have a flatting range shallower than that.  
On the flop i think donkbetting is good, you risk less chips than checkraising and you can even double barrel turn small if you get called, when your c/r flop you cant really barrel turn without commiting your stack as the pot will be more bloated.   You can c/c and if turn is check check and he doesnt continue barreling he probably has air or a bluffcatcher so when u miss you can bluff river with a good % of times he folds.  You can even c/c and lead blank turns, its hard for villian to play back this shallow with air.

RE: Flatting range @ 12-15BB

The question was partly prompted having recently rewatched Mersenneary's BB end game video.
He suggested that @ <15BB, without strong reads, generally if we can profitably 3b jam a hand from the BB, it would be better than flatting because the 3BB we win when villain folds has such a high relative worth at that stage of the game and we will find it difficult to play OOP postflop with so little money left behind.
 
I would be very interested to hear your philosophy on designing 3b jamming and flatting ranges vs different opening + postflop frequencies at these depths.
Consider 12BB.
If we flat a min raise, we will have put 2BB each into the pot, seeing a flop with 4BB in the pot and 12-2 = 10.0 BB behind.
This gives us an SPR of 10 / 4 = 2.5
and we will only require 10 / (12*2) ~ 42 % equity to stack off on the flop.
 
Consider 15BB.
15-2 = 13.0 BB behind
SPR = 13 / 4 = 3.25
required equity to stack off on flop = 13 / (2*15) ~ 43%
 
At these depths, depending on villain's opening range and postflop frequencies (which yields an expected value:bluff ratio vs different lines on various board textures), we will basically be playing a 2 street implied value game?
But do we make enough on our marginal implied value after flatting that it is better than taking a profitable 3b jam?
Especially if we have a lot of fold equity preflop vs wide openers which we forgeo by flatting?
