This hand was the first hand at the table .Both players unknown.

I'm thinking a 3bet pre would be better to isolate the BTN because he's not fully stacked so I assume he could be fishy (they usually are at this level)

The original raiser didn't cbet so I suspect he's just giving up. If he did cbet and BTN calls then I haven't a clue what would be the best play.

I checked raised the BTN for value against a range of :
QQ-66,AdQd,AJs,AdTd,Ad9d,Ad8d,A7s-A6s,Ad5d,Ad4d,Ad3d,Ad2d,KdQd,KJs,KdTd,Kd9d,Kd8d,K7 s-K6s,Kd5d,Kd4d,Kd3d,Kd2d,QJs,QdTd,Qd9d,Qd8d,Qd7d,Q6 s,Qd5d,Qd4d,Q3s,Qd2d,J2s+,Td9d,Td8d,T7s-T6s,Td5d,Td4d,Td3d,Td2d,98s,96s,9d5d,9d4d,9d3d,9d2 d,8d6d,85s,8d4d,8d3d,8d2d,76s,6d5d,6d4d,6d3d,6d2d, 54s,5d3d,5d2d,4d3d,4d2d,3d2d,AJo,A7o-A6o,KJo,K7o-K6o,QJo,Q7o-Q6o,J6o+,T7o+,98o,54o.

I don't think villans range changers much for calling the check raise. If I'm correct I still have 61% equity.

If the button is an unknown, why do you assume he will call a raise and then a check/raise with small aces and small kings? Can you really give him such a wide range just because he is playing short-stacked?

Well at 5NL most of the the short stackers are really loose. Plus his bet size on the flop seems bad that's why I made the assumption.
