Help with assigning ranges for villain.

Hello

How many bluffs should I put in a villains range readless? Also, say he's been playing aggressivly and shown up with a bluff or two how does this change things? I know I should increase the amount of bluffs in his range, but I believe this is also situational dependent. The thing is, I was doing some math and was calculating how much equity I needed in order to call a flop c/shove. This was actually from one of coffeyays leakfinding videos and he said that in a 3b pot if you bet half pot you should bet/call it off with AK. But when I made his range I didn't get quite enoguh equity vs his range to make that call. So I tried to add in like one-or-two "spew" hand or bluffs with no equity and that increased my equity alot, like 5-10% and then I was able to make the call. The board was like 83Q. 

So 3b pot t100 and half pot c-bet on the flop so (23-10)/(2*23)=28% vs his shoving range. So I gave him a range of- TP, two pair, mp, fd. Which gives us 25.3% equity with AK.

(K8s, Q6s+, J8s, T8s, 98s, 86s+, KcJc, KcTc, JcTc, Kc9c, Jc9c, Tc9c, Ac7c, Kc7c, Jc7c, Tc7c, 9c7c, Ac6c, Kc6c, Jc6c, Tc6c, 9c6c, 7c6c, Ac5c, Ac4c, Ac3c, Ac2c, KQo, K8o, Q7o+, J8o, T8o, 98o, 87o)= Ak have 25% equity here. Is this an okay range? I know it's kinda wide. Anyone to my point here, if I add one spew hand for example 72o I get 29% equity, so then I have enough too call. So how many spew/bluff hands should I put in my villains range readless, and how does this change with reads?This is probably board texture dependant as well since most opponents tend to bluff more on dry boards, but I stil have no idea of how man I should put in.

Semi bluffs

maybe instead of adding total bluffs like 72o, add semi bluffs like KJ and KT without the FD. They could have 2 overs to 2nd pair and a backdoor straight draw and even maybe a backdoor FD. Also you could add some hands that have 1 over to the 8 and also backdoor FD and straight draw. Id add all hands that have gutshots and 2 overs to the 8. Let me know how the equity looks after that, interested to know but too lazy to calculate it

"Also you could add some

"Also you could add some hands that have 1 over to the 8 and also backdoor FD and straight draw"
e.g. T7, T6, 97, 96
 
"How many bluffs should I put in a villains range readless?"
and im assuming its a readless reg cuz i would just 3bs AK vs an unknown.
 
"Also, say he's been playing aggressivly"
I think the point to be taken here is that you cant alway let loose aggro regs win pots with the bottom of their range. If you always let their semi bluffs, bluff your semi bluffs you will get run over.
 
but dont over adjust cuz then you will pay them off too much if they decide to tighten up
 
 
Hope that helps :)

Decision to call

@ 25.0 BB
When action goes:
Pre: min raise 1.5 BB, 3b to 5.0 BB, call: P = 12.0 BB
Flop: cbet 0.5 P, jam, call

S
25.0

 
 

SB
0.5

BB
1.0

P0
1.5

 
 

R
1.5

P1
3.0

3b
5.0

P2
8.0

C
4.0

P3
12.0

 
 

cbet
6.0

P4
18.0

J
19.0

P5
37.0

C
13.0

P6
50.0

 
 

O
26%

 
BB has to call 13.0 BB to buy equity share in 50.0 BB pot.
He needs at least 26% equity for calling to be better than folding.
As stacks decrease, the equity required decreases signifcantly and so folding AK would become a signifcant mistake on many boards. 
 
The equity required for different effective stacks given the same action, up to the point where your cbet in 3b pot gets jammed over is shown below:

S
e

25.0
26%

20.0
20%

15.0
10%

 
Against top pair you likely have 6 outs twice on the flop ~ 6 * 2 * 2 = 24% equity.
Villain just needs to be jamming a tiny amount of draws or bluffs to make calling off with AK correct @ 25.0 BB.
Any shorter and it becomes a mandatory call against most villains.

Thanks!

Thanks, appreciate the breakdown of the math. Very useful :)
