Dutch Tactics
Sure 17... Qh3 is winning altough I feel that two exclams may be bit excessive as this move is not that exceptional (there's no sacrifice involved and it's very obvious as well as this kind of threats need to be alwayss checked first).
After 2... e6?! 3. exf5 exf5 the pawn on f5 looks a wasted move and moreover a weakening. The main idea of the Dutch 1... f5 is to control e4 so the laws of logic dictate that you must take with 2... fxe4. White will sure have compensation but at least you have an extra central pawn to show for it.
6... f4 7. 0-0 fxe3 8. Re1 Qd8 should be good for you, I think. Therefore 6. Be2 is better option for white - it doesn't matter that much that white looses time with Bd3+Be2 as your queen is not that well placed in e7.
i am not sure that you could save the knight, but 11...Nb4 keep the material even?
 At a quick glance, I cannot see the idea behind that move; maybe you have the lines to show that? Thanks.
well, i could just show you, but you would probably learn more if you did it yourself. hhahaha
yeah, i'm dumb. i missed something in my calculation. or i was so brilliant last night that i am back to my normal level and can't see it today. can we go with that? i didn't think so, but it was worth a try.Â

Ok, I was speaking about my personal subjective impression. I've seen some of your previous posts and I've seen you make moves that impress me more than this one. 17. Qh3(!) is very strong so maybe I could give it one exclam but really when the g2 pawn in front of the castled king is pinned with rook like here you always consider moves like Qh3 that threaten chekmate. When we take into account that Bd6 also participates in the attack it quickly becomes clear that this move should be played.
I was thinking that I did not want to release the tension between the pawns so early and open up my f-file when I was not ready to defend it adequately, at least that's what went through my head during the game so that is why I chose my move; I am not sayiing that it was the correct move and I figured that White does have "compensation" for the pawn so I would not gain anything really.
Let me still try to convince you that 2... e6, while not certainly a loosing mistake, leads to somewhat inferior position and that 2... fxe4 is infact the way to go. In general if your opponent sacrifices a pawn in the opening most of the time you should accept it. Just don't hang onto extra material with any cost and let your opponent gain a decissive development advantage - sometimes it's a good idea to give the material back in order to finish your development. See the diagram below for some illustrative variations. -
