Its live $1 $2, straddles are often, this hand is w/o straddle.
Hand before I 3-bet AA from SB HU vs BTN who opened $6, folded KQo - he showed the hand.
Now I am BTN and have Td7d and call him who is HJ and he is opening/raising to $7. Its 3-w...

Flop($22): 7hAh7 its check, check, I bet $15, next guy utg limp/caller folds and original raiser c/r to $45....

I have $215, he covers me... He is very good player, dont remember him bluffing ever....

Dont know what to do and what hand he might have to do this move w/.... He reps 7+...
He doesnt have A7, nor K/Q 7 most likely, seems like some KhQh or maybe AK/AQ.
7 is way more in my range than his, he might put me on steel though... Very unusal spot for me...

Any thoughts?
