Dealing with "shove/fold only" guy strategy

hi all, at 3.5s, i run into some guys who only shove/fold preflop and shove on flop. I had difficultly dealing with them as it seem that they know when to shove preflop.

Readless, I am very aggressive, minraise wide from 45o+ and get very annoying preflop shove by villian, lose 2bb few times.

Each time when i bb, call, villian seem to know that my cards are weak, so he preshove. Each time i minraise, he preshove or fold. He had open shove about 30% stats, preflop.

And also when i call sb, to see flop. i check and he just really shove. NO bet No check. really annoying. most of my cards didnt hit one card on flop,

Any advise? or i am fish...?

Tips

Tips:
 
OOP
Estimate shoving range @ effective stack S = ?
Call when your equity vs this range, e > (S-1) / 2S
Fold otherwise
 
IP
Estimate villains 3b jamming range @ effective stack S = ?
Raise call hands which have correct equity to raise call vs his 3b jamming range, e > (S-2) / 2S
Contract your raise folding range and limp middling hands to see how villain reacts to limping.
If he remains aggressive, jamming a lot, its ok to expand your open folding range and simply expand your raise calling range so that you have a pure wide value range.
 
Your goal against this guy, as strategically shallow as it sounds, is to pick up a hand with decent equity vs his range and get it in.
He's learned the value of aggression, but he's overdoing it => especially at the deeper stack levels of the match.

Hi Cdon3822,If i oop, bb

Hi Cdon3822,
If i oop, bb with Q9o, equal stacks 100% effective, call villian. flop 23K or 339 or A8K, he shove flop, +ev to get it in ?
Similarly IP, villian never 3bet and only shove, call shove with 89o+ onward in, +ev too?
I am not familar with Stack formula, from what i understand, let say, 100-2 / 2x100 = 49%, am i right to say that, whereas 100 is percentage of stack ?
Sorry new to hu, starting playing and learning to deal with types of players. really annoying and same time fun. :)

I thought you meant villain

I thought you meant villain only pushes all in preflop or folds. 
In the equations posted, S = effective stack in big blinds (BB)
 
So for example if villain is open jamming first hand of a hyper turbo, S = 500 / 20 = 25BB
We would need to call (25 - 1), because we've already posted 1 BB for our equity share of the total pot = 2S
The equity we require to be indifferent between calling and folding is (S-1) / 2S
Which @ S = 25BB, e = 24 / 50 = 48%
So we are better off calling than folding if we have > 48% equity vs villain's open jamming range. 
For example, if we think villain is jamming a range of [88-22,A8-A2]
The hands with at least 48% equity which we can call with include [AA-33,AK-A7,Ax6x,JxTx,Tx9x]
 
Likewise, when you min raise then get jammed on, you have put in 2BB into the pot so need to call (S-2) for your equity share of a 2S pot. 
So to call a 3b jam you need, e > (S-2) / (2S).
For example, if @ S = 15BB, villain 3b jams a range of [QQ-22,AK-A2,KQ-KT,QJ,Kx9x-Kx5x]
Then the hands which you should be raise-calling with are those with e > 13 / 30 = 43%
Which against this particular range are [AA-22,AK-A5,KQ-KJ,Ax4x-Ax2x,KxTx,QxJx]
 
The point is, you need to put villain on a range of hands based on the frequency that he is playing + any additional information you have based on what you've seen villain turn up with and how he plays different types of hands. 
As effective stacks decrease, it becomes mathematically correct to get all in with a much wider range of hands because the blinds are worth so much relative to your remaining stack.
