205 ( +1 | -1 ) The Muzio gambit? What, are you nuts?
Ok, actually, that is what someone wrote to me when I played the Muzio on ICC. 10 moves later, when I was checkmated, I thought: "maybe I was crazy" and haven't played it since.
In this game, I'm not sure your main problems had anything to do with lack of queenside development. [Full disclosure: I'm certainly not good enough to comment as competently as so many others, but I'll just offer some thoughts]. It just seems like both sides made some real mistakes, but you had the misfortune of making the ones that were taken advantage of, especially after having chosen an opening that rarely allows for anything but nearly flawless, or tactically brilliant, play. In particular you seemed to make a number of pawn moves that had no real aim in mind (though I'd enjoy hearing your thoughts, if you did have a real aim in mind: I may be missing something).
Well, here are some things I noticed in my short glance through the game:
7. Nc3 is a mistake -- as you found out. Black didn't immediately capitalize on it, though (his own mistake). You are of course allowing a nice little double attack. I think 7. c3 would be stronger.
8. d4 Again not spotting the tactic. 8. Qxf4 would be much better, or even 8. d3
16. b4 What's the purpose here? Just a small annoyance to the black Queen, who's better off elsewhere anyway. 16. Nf6+
Later, when you were pressing your attack with the queen, you too often let up the pressure
23. b5 Again, not much reason to move this pawn. Qf7+ is stronger
26. h4 There's no reason to be moving the pawn when you've got your queen nicely positioned. You should have moved Qe8 to have any chance. Your move allows 26... b6 (which your opponent didn't see).
27. h5 An unnecessary pawn move... again, you would have been better off moving Qe8
These are just some of the weaker moves I can see -- I'll let stronger players, if they show up, handle the more difficult problem of a flaw in general ideas.
216 ( +1 | -1 ) Analysis7. Nc3 isn't a mistake, just uncommon. 7. c3?!, on the other hand, just isn't fast enough and allows Black to develop easily with 7... Bh6. The main line is 7. e5 (for example, 7... Qxe5 8. Bxf7+ Kxf7 9. d4 Qxd4+ 10. Be3)
7... c6 is an interesting reply. The most testing, obviously, is 7... Qd4+ 8. Kh1 Qxc4 9. b3 Qe6 (9... Qxf1+ is interesting but probably not good enough) 10. Nd5, when White has some play for the pieces. Look at some of brunetti's games for more on this line.
I find it incredibly difficult to believe that 8. d4 can be good after 7... c6. Possibly 8. b3 is best, and 8. d3 is another option.
10... Ne7 is a mistake, after which White should play 11. Be5. If 11... Rg8 then 12. Nd5! is very strong. Better is 10... d6, when Black can play ...d5 on e5 and develop the rest of his pieces with ...Be6, ...Nd7, ...0-0-0 etc.
13. e5 (idea of e5-e6 or Bd6) is better than 13. Nd5.
14... Qxc2? is just ridiculous. Black is already up two pieces and you're going to take a pawn? There's no way the Queen can be considered well placed on c2. The obvious move is 14... Qc5, when the Q prevents Bd6, and if 15. Nf6+ the Q comes back to e7. However, I think 14... Qxf1+ is better, when after 15. Rxf1 cxd5 Black has three pieces and a rook for the Queen. After 16. exd5 f5 Black holds easily.
Same essential position after 15. Re2?. White should just play 15. Bd6 when Black's Queen is totally out of play and White has major kingside threats. For example, 15. Bd6 cxd5 16. Bxf8 Nxf8 17. Qxf7+ Kh8 18. Qe7 Kg8 19. Rf7 Qb2 20. e5 Ne6 21. Rxg7+ Nxg7 22. Qd8+ Kf7 23. Rf1+ Kg6 24. Qf6+ mates. Better than 15... Qc5 is 15... Qxe2.
16. b4 is very helpful, as the Q no longer controls d6, so White can play Bd6 and Qxf7+. Compare to 16. Nf6+? Bxf6 17. Qxf6 Qe7 18. Qd4 d5.
21... Qxf2 is mostly a botched attempt to bail out with reduced material, but Black could have done this advantageously much earlier (14... Qxf1+).
23. b5 is incorrect, but 23. Qf7+ just leads to repitition after 23... Kh8 24. Qe8 Kg8. Why not the most obvious move: 23. exd5?. The knight should have gone to e5, not d4, to guard f7 and be supported by the ...d6 advance. In that case, White can get a perpetual check with Rxf8+ and Qxe5, but nothing more.
24... Nxb5 is also a mistake. Black needs to develop the queenside with 24... d6. If 25. Rf7 then 25... Be6.
Instead of 26. h4 White should play 26. Qe7 Kg8 27. g4 d6 (or 27... b6 28. Rf7 Bh6 29. g5 Ng6 30. Qf6 Bf8 31. h4) 28. Rf7 Bh6 29. g5 Ng6 30. Qe8+ Bf8 31. Rf6, winning with Qf7+ or Rxg6+.
