I think your initial mistake was a conceptual one.
You were fixated by a King-side attack when maybe other (better?) plans were available.
Look at the following position:
Qd2 pretty much telegraphs your intentions. You intend to castle Queen-side (into the attack, by my way of thinking) and smash through on the King-side.
Bd3 is more flexible and allows your King to castle short, followed by active operations on the Queen-side or in the centre.
I'd be looking at weak squares (b5, c7,e5) and castling King-side.
I just finished a game with a player 600+ ratings higher than me.. the opening went well for me. [at least in my point of view, the computer analysis (2000 rating for free basic members like me) disagrees]
i never thought that i have so many flaws in my moves before this game was analyze.. IN FACT, im devoting not less than 2 hours a day in this position solely because i'm thrilled playing such strong opponent and i want to know how far will i go.. over the board analysis on this game, i decided my first mistake is at least at move 13.. I'M WRONG!! so i am actually thankful that even free basic members like me has a chance to have my game analyze by the computer once a week..
during this game, a tourney with a theme of modern defense, i launch a premature kingside assault, i castled long for the purpose of pawn storming the castle but made a lot of innacuracies and eventually fallen into heavy material deficit..
i titled my post this way because with this "ANALYZED" game, at some point i am a rook down and the computer keeps suggesting a move that exchanges the queen..
and of course, no human would ever trade queens when down material unless forced! so computer's computation, I BELIEVE, will never supercede human's perspective afterall.. in this game i am definitely defeated at 21. Ne3+ but i chose to play and survive until 32 moves later..
please, give me some insights with moves:
a) 13. h4? - my plan here is to pawn storm the castle.. how should i attain this goal? if it is impossible, what should be my plan then? (the game has transposed to sicilian dragon if im not mistaken, right?)
b) 14. Rdf1 - is Be2 really necessary? wouldn't i be at a disadvantage if i have 2 knights against bishop and knight in such open positions?
c) 18. Na1 - what do you think of the only alternative Ne4?
last:
d) i know if not to tactical inaccuracy for black i should have been lost early on but what do you think of the position after 48. Kxa2 Qc2+.. is there any saving resource that i've missed? if there is, please give me some variations so that i will study it when i have a free time..
thanks in advance to those who will help me..
good gaming to all of you!
cheers!
