How to defend vs steals from him?
Can I 3bet with intention of double barrel, because he should call preflop with wide range, but how can he call 2 streets?
Do I have to defent K7s at all or wait for more plaiable hand?
Or call preflop with intention of raising cbet on flop? He fold to raises on flop small sample, but I believe he should fold because of wide preflop range.
