The stats i had on him where 30/19 over 74hands and steal %60
1st hand:



I decided to flat here because he was stealing a lot and i thought i could get some value post flop from him.
What should i do on this turn card? I have a straight draw but i might as well be drawing dead here so i wasnt too happy about it and decided to fold.

The 2nd hand agaisnt the same player:





What range would you guys reshove here?

hand one - why lead when you prolly have the best hand against an "aggro donk"? never understood this play

I check/shove turn or even c/r flop here

then folding turn seems weak - think about how he sees you - leading flop then checking turn? looks like you flopped bottom or middle pair and are afraid of turn - you allowed him to play perfectly - yes there is a flush but you said yourself he's aggro - just get it in and be happy imo

hand 2 - have you seen him raise this big before?

I like the Chindo's logic with regard to hand 1. villain's bet OTT is smallish and tipical for laggy players imo. It indicates no real strength. folding is out of my options, just go for it and shove OTT.
Hand 2: good shove. Villain's big raise might be intended to only give him better pot odds to call if reraised.

H1: c/r flop and get it in

H2: 19% PFR combined with 60% steal isn't laggy enough to reshove A8s here imho

Hand 1 I'd check shove flop. You have the best hand most of the time + it's a drawy board. donk betting small is bad and check callings bad, so is c/f turn
Hand 2 you have no fold equity and only if you have some sort of read you could be ahead I'd have reshipped

Check raise flop, or bet bigger. As played, have to call the river.
Fold second hand. Id go with ATs+

Ch/shove flop indeed. 2nd i agree with Mangooooo
