Example of a king side attack (g3; Bg2) with tactical possibilities

This post presents a recent game I played with black against kingschild77. I have annotated the game, sharing my thoughts on the game and presenting variations I found out only after the game.

I would really be happy if anyone would be helpful enough to add their thoughts aswell.

I like the game especially because in the practical attack against the white kingside, I had the privilege to calculate a lot of cool variations.

I would not have castled on the side you used your light squere bishop. It gave your enemy a nice opening after you captured. I think that was a big mistake which costed you your game. I would next time just castle on the other side of the bishop that's being fainchettioted. Hopefully that helps. -Kingdom_Hearts

Thank you for your reply. Unfortunately you have misunderstood and actually I was playing black pieces and my opponent was white. The confusion probably came because I didn't rotate the board. With your reply did you mean that white shouldn't have castled on his kingside? If so, then perhaps you are right, although there is a setup called the king's indian attack where white does so. The problem with fianchetto on the kingside of course is that you have to know how to play against the pawn push (very actual in the sicilian dragon etc). 

My move 0-0-0 still bothers me ... Can anyone tell me if its positionally justified? Or should I have played something different ... if so, then what?

13...d4 wins a piece(knight) since double attack on queen and knight as you told.Next time try to be more careful before running your plan maybe there is some tactic that gives you clear advantage.(Do not blindly follow the plan,learn to be flexible in it.)22.Ne2 is a good defence,but you had ...Qf2+
23.kd2(the only move) and then 23...d4 a powerful attack I guess.After d4 white may want to play 24.Kc2 but he will lose the knight ...Qxe2+ so he cannot play this.So I do not know any move of White that makes you not to play ..exd4+ and then the king has to leave the knight.I believe in this line you could checkmate earlier.:)

Thank you, I had a brief look into your suggested 23. ... d4 with the continuation of 24. Qe6+

1. e3 2. g3 3. Bg2 is not considered very good. Especially if you've no idea what to do. Here, it seems your opponent didn't know what to do, and you responded logically with the sharpest idea: ...Be6-Qd7-Bh3 is a nice plan. (As black I play the hippo, where Be3-Qd2-Bh6 is the same theme and white's most aggressive try for advantage.)

6. Qb3 wasn't good, as your e6-bishop is staring at Her Majesty.

And thanks to that, 8. d4 was not really good by your opponent, it's true. But the choices aren't many. 8. Nc3? d4 wins a piece, 8. d3 d4 9. Qd1 dxe3 asks white which structural problem he wants to have, and 8. 0-0 d4 (again) 9. Qb5 d3!? is an interesting sac to try.

9. Nd2 was better, accepting a space disadvantage.

10...f6 I don't think was the best way to exploit the e5-pawn. The calm ...Ne7-Nc6-Qc7 or something of the sort, probably with ...0-0 somewhere along the way. That would probably win the pawn, or at least force white into strange contortions to hang on to it. Thing is, your d-pawn's as weak as his e5-pawn, and once you let him trade it off he has potential pressure on your 2 central pawns.

12...0-0-0: Wild but probably safe. As long as you quickly initiate kingside play before white can go for your king.

13...d4 won a piece, yes. Note that this tactic was hinted at as early as move 6. Should've been considered at every move up to now.

15. Nxe4 - I like this idea. Black has a few tactical countertries which must be examined: first, 15. Nxe4 dxe4?! 16. Rxd7 Bxb3 17. Rxd8+ Kxd8 18. axb3 Bc5 and white's a pawn up with the bishop pair. Next, 15. Nxe4 Bg4?! 16. f3! (16. Nxf6! Bxd1 17. Nxd7 Bxb3 18. Nxf8 Rhxf8 19. axb3 a6, probably white's better) Nxe4 17. fxg4 and white's better thanks to black's exposed king. The line you gave there is probably the best for black, but even then it's not great as white's a pawn up with good structure (I think black's attack can be parried, but with a lot of effort.)

17. Nxe4 is again interesting. Another good line given there. I'm thinking 17. Nxe4 Bxg2 18. Nxf6 Qf5!? looks fun and equal but probably falls for some tactical shot somewhere.

17...a6 looks OK, but potentially a little worrying. White might have some fishing-pole style attack after 18. Bd2!? axb5 19. Rdc1+ Kb8 20. axb5 then Qa2/Qa4 and an obvious attack. If 20...Rc8 21. Bc3.

21...Qg2 22. Ne2 is not immediate game over. White buys a little time and might get his king to b1 given time.

Instead, I think 21...Qxg3+ 22. Kd2 Rh2+ 23. Ne2 Rxe2+! 24. Kxe2 Qg2+ 25. Ke1 Ng4 26. Rd4 (26. Rd2? Qg1+ 27. Ke2 Nh2! with what looks like mate in all lines) (26. Rxd5 Bb4+!? 27. Kd1 (27. Qxb4 Qf2+! 28. Kd1 Rxd5+) is probably safest but looks insane) Be7 with a heavy attack.

Tried looking at 24...Bb4+!? but I'm tired, as you can guess by the above portion of the post. Spotting 27...Nh2 in the above note took a lot out of me. Basically, changing the order of ...Rxd5 and ...Bb4+ may yield some advantageous tactics.

Well after the mess you were up a piece and should've won easily. Which you did, quite a lot easier than it could have been.

Tactical slugfests are tiring to look at. Personally I'd have avoided the entire mess by not playing 10...f6 and going the slow route of winning the e5 pawn. But still, nice game and good annotations.

Bonus: 21...Qxg3+!? diagram
