Played this hand about a week ago but I was unsure about my play. Blinds are 600/1200 with 200 ante. I recently got moved to this table and have about 54k. Im on the button with 55 and it folds to CO who min opens and has me covered. I flat even with the blinds being relatively short (20-30k). They were older gentlemen and I didnt see them squeezing light very often. Both blinds call and we see a flop of Q105ss. Checks to CO who bets 6k. For the same reason I flatted pre I decide to raise as I dont think the blinds always jam flush or straight draws. I make it 14k. Folds to CO who calls. Turn is Ac. Villain leads turn for 20k. I have about 38k behind at this point. Im pretty readless and couldnt figure out a range other than KJ, A10, AQ. I guess its possible that he could do this with Axss but without a read Im not sure. I dont think he ever has a set here because he probably just 3 bets flop. Curious to know what people think about his range here and if this is just a snap jam.

Should also add that the Q10 are spades and I have the 5s.
