Slow Start | Strong Finish

your comment for the 11th move is somewhat unjustified, the space is even, if not in your favor. however, the push is still very good in terms of opening up play in the center

being in 'autopilot' is bad, but your moves seem to be preparing for a e4-break, so it could be considered a plan. also, hint: study the semi-slav, its a common defense by black against the queen's gambit (I like to play the gambit too!)

i haven't fully taken the time to think about it, but black has a better 17th move, 17...Qd6, which (i think) holds the position together but black's kingside is being pounded

your last move is brilliant. Don't judge me by my chess.com rating, but I wouldn't have seen that move under that type of time control pressure. (Im not good at blitz)

A good game with a crushing final attack. Well done! Maybe you played slowly but that is not necessarily always a bad thing. I don't think you were worse at any point.

I think the position after 8. Qc2 (and probably also some moves after that) is theory altough arrived via unusual move order. 11. e4 is very typical idea in these positions. It's difficult to give any definite evaluation of this decision without any deeper analysis but I don't think it can be too bad here either. 17. d5! seems very strong.

Although I agree with many of the comments about your 11th move- the tempo is in your favor after this move- You played on the whole strong move your oppenent had to react to. Well played.
