10-20NL HU Full Tilt

[PMP07]

Sorry in advance for no converter. Playing 10-20 heads up on tilt the other day, and I was playing just a random guy HU no reads or history with opponent. He had been playing fairly aggressive winning quite a few pots early in the match, and I believe floating some flops as well against me. Is this hand standard or no? I don't post often but would love to hear some thoughts.

Opponent:$3.4k
Hero:$2.2k
Opponent raises 60 on BTN, I call from BB with A7offsuit.
Flop Q Q 7 w/ 2 clubs(I do not have a club)...I check he bets 100, I raise to 300, and he calls
turn is 6, I check, and opponent bets 620. I have approx 1.8k at this point

All thoughts on hand appreciated...and again sorry for lack of converter...I'm new to this and I'll definitely correct it in future. Thanks
