help me

turning stone 20 40
fold to me in the cut i razzzzze it up wit JQ off
blinds call flop is KQ6 3 suits
sb is has got to be 90 and will never bet or raise unless he has a 2 pair minimum will just call every pair down
bb seems to open preflop with bad hands alot but havent seen him donk bet like this yet
sb cks, bb leads ,i call first mastake?

the guys range is basically any Q or any K or 10 9
i think they will almost auto defend my raises so even hands like k2 or Q2 are possible
anyways i called the flop so did the old tymer

the turn came a blank sb cks bb bets again and we both called again
river a 10 came off the bb bet and i folded

i appreciate the help guys
these donk bets are hard to tell where you stand
