1. c4 Ngf6 {Personally, I would play f6 here or later, as the pawn structure will then serve to blunt my bishops. But of course, Ngf6 is playable.}

2. b3 d5 {yea, so d5 I guess falls into the “tricks of 960” :) This move is really bad as black’s king is rather exposed. Much better is b6 or even d6 keeping the position closed. Black should keep the pawns in front of his king for the time being, at least until his king is castled.}

3. cxd5 Nxd5 4. e4 Nf4 {This move loses so N5f6 was preferable. After Qd3+ Nd7, black is cramped and has a bad position, but he is not losing.}

5. g3 {so we can see now that black will lose a piece and with it the game.}

5… Ng6 6. Qd3+ {Nd6 e5 and black’s pretty much done. I didn’t even notice how weak Black king was until black played d5} { Black resigns } 1-0

1. Ng3 e6 2. e4 Ng6 3. d4 c5 4. b3 {maybe c3 holding the center with pawns is better. }

4… b6 5. dxc5 {even here better to play c3 than give up the center. Also, White would have retained the option of playing d5 restricting Black bishop on a8}

5… Bxc5 6. Nd3 Be7 7. Be2 Nd6 8. Bf3 {maybe f3 is possible. At least White wouldn’t get doubled pawns.}

8… Nh4 9. Qe2 Nxf3 10. gxf3 {Qxf3 is obviously bad because of f5}

10… g6 {designed to prevent Nh5}

11. O-O-O O-O-O 12. c4 {a good move, creating a bind on d5, however, black can still free himself by playing d5 himself.}

12… Nb7 {Wasn’t too happy about knight’s placement on d6 :) }

13. e5 {maybe White should hold off on this as it increases the scope of Black bishop on a8. Maybe f4, with f5 ideas. White can always play f3 again if need be.}

13… d5 {clearly best, freeing black’s central position.}

14. exd6 Nxd6 15. Ne4 Nxe4 16. fxe4 f6 {I don’t think I should allow e5 with my pawn on f7. f6 stops it in that I can go f5 now, when White’s e5 would have been counter-productive.}

17. Kb1 Qc6 {starting to build up pressure against the center. Notice how black has an edge now because of his two bishops and better pawn structure. Hence, Bf3 earlier might not have been
best.}

18. Rge1 Rge8 19. f3 Kb8 {no need to rush for black}

20. a4 a6 {contemplating b5. I don’t think a4 was so helpful, however, it’s already difficult to play for white.}

21. Rc1 Rd7 {simply increasing the pressure by doubling rooks.}

22. Red1 Red8 23. Nf2 f5 24. Rxd7 Rxd7 25. Be5+ Ka7 26. a5 {rather desperate I think, but Bc5 was coming after which white’s position is falling apart anyway.}

26… bxa5 27. Rd1 Rxd1+ 28. Qxd1 Bc5 29. Nd3 Bd6 30. Bd4+ Kb8 31. Ne5 Qc7 {yea, so Bb6 scared me for a second, but Qe7! and black’s fine. After this the two bishops should win the game. Black’s also a pawn up. So, earlier white maybe should have chose c3 to protect the center and then maybe play d5 themselves; also, f3! instead of Bf3 would have been more resilient as white’s bishop looks blocked, but it would have been able to free itself eventually with moves like g3 and f4 later, followed by Bf3, when white’s doing fine. } { White resigns } 0-1

1. g3 d5 2. Bg2 Nf6 3. Ned3 Nb6 4. Ne5 c6 5. a4 Nfd7 6. f4 f6 7. Nxd7+ Nxd7 8. a5 e5 {maybe a6 is better as when White plays a6, black experiences pressure on the long diagonal.}

9. fxe5 fxe5 10. a6 b6 {notice White pawn on a6 is rather annoying.}

11. c4 Nf6 {if Black pawn was still on b7, Black could take on c4, but since he let White play a6, this is not possible.}

12. h3 {I want to play g4, with the idea of kicking Black knight away which is protecting the center.}

12… Be6 {maybe h5 was better and then Be6}

13. g4 h6 14. Nd3 Qh7 {I missed this move, very annoying pin on my knight!}

15. cxd5 Bxd5 {probably best, as it is clearly in Black’s best interests to trade light-squared bishops}

16. Bh2 Re8 {maybe just Bd6 was better as now Black cannot castle short as he moved his rook. I think Black would much rather have his king on g8, than on the queen side!}

17. Bxd5 Nxd5 18. Qg2 Bc5 {stopping my intended 0-0, very annoying! It’s hard for me to unpin my knight.}

19. e4 Bd4 {probably forced as e5 is hanging, but on second thought Bd6! might be better in view of my next move.}

20. Ra4 {threatening Rxd4 at the right moment. It’s rather difficult for black now.}

20… c5 21. Ka1 {I thought about Rxd4 immediately, but I thought it best just to free my knight first as the threat is not going anywhere.}

21… Nf6 22. Rxd4 {things start to heat up around this point!}

22… cxd4 23. Nxe5 Kc8 {forced, as Qxe4 Rc1 would be very pretty, With Nd7 mate to come! If Rxe5 Bxe5+ Qxe5 Qb7 mate! Again we see how powerful the pawn on a6 is. :) I don’t think it should have been let that far.}

24. Rc1+ Kd8 25. Nc6+ Kd7 26. e5 Qe4 {Have to admit, I missed this move. Fortunately, my position is still very good.}

27. Qg3 Nd5 28. e6+ Rxe6 29. Ne5+ Rxe5 {I wonder if Ke8 is better. e.g. Re1 Qh7 and I’m not sure if I have enough compensation. After the text, white is clearly better in the resulting endgame.}

30. Qxe5 Qxe5 31. Bxe5 g6 32. Bxd4 Nb4 33. Bg7 h5 {if Nxa6 Bxh6 Rh8, I have g5.}

34. gxh5 gxh5 35. Rc4 Nxa6 36. Rh4 Rg8 37. Bc3 Rg5 {forced to protect h5, but Ra4 is probably winning for white. Black’s main problem is the bishop and rook work together much better here than the knight and rook.}

38. Ra4 Rg1+ 39. Ka2 Nc5 40. Rxa7+ Kc6 41. Rh7 Rg5 42. h4 {Here it should just be a matter of technique, as white’s forces are clearly stronger than black’s.}

42… Rf5 43. Rg7 Ne4 44. Kb3 Nc5+ 45. Kc2 Ne4 46. Rg6+ Kc7 47. Kd3 Nf2+ 48. Ke3 Ng4+ 49. Ke4 Rf1 50. Rg5 {this is hopeless.}

50… Nf2+ 51. Kd5 {with Rg7 idea as well as taking the pawn. }

51… Nh3 52. Be5+ Kd7 53. Rxh5 { Black resigns } 1-0

{The main reason I think black lost was because he underestimated the danger of the pawn on a6. Playing a6 himself would have been safer. Also, Bd6 instead of moving his rook to protect e5 earlier would have allowed him to castle king side, thus sidestepping the danger. Finally Ke8 instead of Rxe5 may have given him an edge as my attack may have been running out of steam. After Rxe5, the resulting endgame is pretty bad for black. A general rule of thumb in endgames: “bishop and rook work better together than knight and rook” The bishop has much more range than the knight and can relocate much faster than its counterpart.}

1. g3 g6 2. d4 Ne6 3. Nb3 f5 {played to prevent e4 with central domination for white. Also, Bf7 may be good}

4. e4 fxe4 5. Bxe4 Bf7 6. Ne3 Nd6 7. Bg2 c6 {I don’t know about this move, maybe white can play d5 here, furthering the scope of the Bg2}

8. Ba5 {maybe a slight waste}

8… Qf8 {Queen was moving anyway}

9. Qd2 g5! {a good move, to prevent f4 and prepare Bg6 Maybe f2 could be a slight weakness in the future}

10. O-O Bg6 11. Rae1 {Maybe Bc3 with d5 to come was better. I feel that opening the center favors white here, as black is rather congested.}

11… Qg7 12. Bc3 {good move, my Qg7 might not have been so hot :)}

12… Qf7 13. Ng4 Bg7 14. Ne5 Bxe5 15. dxe5 Nc4 16. Qc1 {Qe2, staying in the center and attacking my knight, was better. Notice Qxd7? Rd8!}

16… O-O {finally my king is safe! I had been trying to castle for a while now.}

17. h3 {maybe Nd2, trying to trade off black’s active knight, was more pointed.}

17… Bf5 18. Nd4 Nxd4 19. Bxd4 Qg6 {I feel like the edge has shifted in black’s favor here, probably due to white’s lack of aggression. Notice c3 is bad because of Bd3}

20. b3 Nb6 21. Re2 h5 {designed to prevent g4 and maybe play g4 myself, clamping down on the light squares.}

22. Rfe1 {maybe trading with Bxb6 immediately was better, as black’s knight will be improved greatly on e6.}

22… Nd5 23. a3 {correct now, as c4? is dubious to Nb4 coming to d3 next. Also bad is trading with Bxd5 now as the king side light squares will be really weak}

23… Nc7 24. Be3 {I wonder if e6, sacrificing the pawn to open the dark squared bishop, would be worth it. It’s hard to say, but it looks interesting. For example, e6 Nxe6 Ba1! with Qb2 to follow, and pressure down the long diagonal}

24… Ne6 25. Kh2 Kg7 26. Qd2 Rfd8 27. Qb4 {interestingly, my pawns are forked but I fortunately have resources. :)}

27… Kf7 {so Qxb7, Bxc2 and black’s good to go, as Bxa7 runs into Bxb3!}

28. c4 b6 29. Qc3 Rf8 30. Rd2 Rad8 31. Red1 Ng7 32. Bf1 Kg8 33. Bd3 g4 34. h4 Kf7 {notice the king side is blocked and black controls the light squares, giving him an edge. The d7 pawn isn’t too weak.}

35. Bxf5 Qxf5 36. Bf4 Ne6 {notice how the knight is clearly better than the bishop here.}

37. Qd3 Qxd3 38. Rxd3 Nxf4 39. gxf4 Ke6 40. Kg3 Rf5 41. f3? {this might be the decisive mistake. Waiting would be better here, with a probable draw.}

41… Rg8 {notice black’s rooks suddenly becoming very powerful.}

42. Rxd7 gxf3+ 43. Kxf3 Rg4 44. Rxa7 Rgxf4+ 45. Ke3 Rxh4 46. Rdd7 Rxe5+ 47. Kf3 Kf6 {This should be winning, so long as black is careful.}

48. Rdc7 Re6 49. Kg3 Rhe4 50. Rc8 h4+ 51. Kh3 Re3+ 52. Kxh4 {Mine as well, as black is winning and it’s best to end the misery.}

52… R6e4+ 53. Kh5 Rh3# { White is checkmated } 0-1
