we can assume his BTN range is pretty wide and we wount be making a mistake.

we can also assume that because of board texture he will cbet almost his pre entire range on flop.

due to turn check , we can discount 66,44,77,AQ,KQ,QJ,QQ,67s, all this will bet turn .

hands that could take this line and are in his pre range are A5,65s,45s,75s,89s,9Ts,99,55,97s,J9s,Q9s,K9s,A9 these hands he could bet or check the turn, but are def in his pre range and could play them like this.

because he has SD value and board is scary i think he will just call 78s,QT,TT,JJ.

so my decision is to fold on river.
