Hi guys, this is not that serious kind of question like "i have this theory" but is more like I would like to know if this happens normally to some of you guys also.

I just bought the chadder's pack (I used to be a tournament recreational player and runned good gor 2 years with a 20% roi) and i was running good yesterday, the right state of mind and ended more than 15 boxes up (in an 6 hours session) but today i wake up and begin to play and a cross with this mega whale who probably anybody will be happy to have a session with, but for me this kind of players always destroy me (not this first time in happens to me).

so we have our first match, I minraise with A9 off, he reraise me all in and I Called, super donk shows 85 off, of course he wins, as I dont do rematches, a reject his solicitude inscribe again in the lobby but he seeks me out again.

from there we had another 4 matches (i know not enough big sample) but the guy keep sending me all in with 25bb every 2 of 3 hands, "all" in to my minraises, all in to steal my blinds no technique at all just all in or fold, last match ended with him sending "all in" I calling with Q7 suited, he showing 84 suited and of course he winning, this is not the first time this happens to me now it was just 5 boxes but there was anotoher animal with a very similar pattern that got like 11 boxes out of me, this time I closed my computer and went to drink a beer but unfortunately this affected my game and lost against other players when i returned.

when i checked the Mega donk on Poker labs i could not help but to notice the he plays very little but he runs like a god
