Three games are featured here, from the recent Armstrong A team’s 6-2 win over Bray/Greystones.
Board 2: John Joyce vs. Killian Delaney, 5th November 2008 Replay
Slav Defence A game where Killian again demonstrates that being alert tactically is an essential aspect of chess.
1. d4 c5 2. c3 cxd4 3. cxd4 d5 4. Bf4 Nc6 5. e3 Nf6 6. Nc3 e6 7. Bd3 Bd6 8. Nge2 O-O 9. Rc1 e5 10. dxe5 Nxe5 11. Bb1 Be6 12. O-O Rc8 13. Nd4 Qd7 14. Ndb5 Bb8

Position after 14…Bb8
15. Nxa7! So if Bxa7, then Bxe5. Hard to see black winning in another 2 moves or so!
15…Bg4
Incredibly, Fritz recommends 16. Nxc8 here, with 16…Bxd1 17. Bf5 (if Qxf5, Ne7+!) Qc7 18. Rfxd1 and white is better apparently. See the position below.

Possible position after Rfxd1
16. Qb3? Nf3+!

and resigns, because taking the knight is mate shortly, while going Kh1 drops the knight on a7. Ouch!
0-1

Sicilian Taimanov
1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5. Nc3 Qc7 6. Nxc6? Makes it easy for black to dominate central pawn structure. 6… bxc6 7. Bd3 Nf6 8.O-O a5 9. Qe2 Bc5 10. Bg5 Qe5 11. Bxf6 gxf6 12. Kh1 h5 13. f4 Qc7 14. e5 Be7 15. exf6 Bxf6 16. f5 Bxc3

Position after 16…Bxc3
White is trying to use his lead in development to clear the centre and attack the black king, still stranded.
17. fxe6!? Either bonkers or brilliant… 17… dxe6 (Rescuing the bishop is suicide, so he has to take on e6) 18. bxc3 Bb7 19. Rad1 O-O-O Black flees from the centre, but the queenside isnt any safer.

Position after black castles queenside.
20. Rb1! Never be afraid to change plans when the position changes. 20… Rd7 21. Ba6 and the game is effectively over.
21…Qb8 22. Rxb7! Qxb7 (Rxb7 23. Rxf7 is equally ineffective) 23. Bxb7+ Rxb7 24. Qa6 Kb8 25. Qxa5 Rb5 26. Qa6 Rc8 27. Rxf7 Rb1+ 28. Rf1 1-0

Alekhine’s Defence
A curiously one-sided game, where black plays some anti-positional moves right at the opening and never recovers any momentum.
1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. Nf3 dxe5 5. Nxe5 g6?! I question this move. It looks too slow for my liking, but is apparently a mainline. 6. Qf3 Asks black how he intends to defend f7. This isn’t, as it turns out, the most common line, but it seems most critical to me. 6…f6? But this appears a positional mistake. He permanently weakens e6. Better is Be6, or retreating the knight 7. Bc4!

Position after Bc4
Never hesitate to pile on the pressure when attacking. The knight is immune.
7…c6 8. Nd3 Bg7 9. Nc3 e6 10. O-O O-O 11. Re1 Kh8 12. Nf4 Nxf4 13. Qxf4 e5 14.dxe5 fxe5 15. Qg3 Bf5 16. Bg5 Qc7 17. Rad1 Bxc2
Nevermind the pawn on c2, it is more important to develop the last piece. Black is teetering on the brink of a lost position. But he still needs to probably take the pawn and hope my attack backfires. Surveying the position shows black very behind in development and white dominating the central squares, his bishops slice open the centre, and the black pawn on e5 is very weak.

Position after Bxc2
18. Rd2 Bf5 19. Red1 Nd7 20. Qh4 Nb6 21. Bb3 Rae8 22. Bd8! Winning the exchange

Position after Bd8
22…Qc8 23. Be7 Rxe7 24. Qxe7 Bf6 25. Qc5 Re8 26. a4! To undermine the knight 26…Bg5 27. Re2 Qb8 28. Ne4 Bxe4? Dubious, since he now becomes terribly weak on the white squares. 29. Rxe4 Nc8 30. Rde1 Bf6 31. f4 Nd6 32.R4e2 e4 33. Bc2 Nf5

After Nf5
Sets up a nasty surprise on d4, if white isn’t careful. E.g. if Bxe4??, then Bd4+ wins comfortably.
34. Rxe4 Rd8 35. Kh1 Bxb2 36. R4e2 Bd4 37. Qc4 Qxf4 The last mistake. He now faces a mating attack.

38. Bxf5 gxf5 39. Re8+ Rxe8 40. Rxe8+ Kg7 White musn’t forget that black has a potential mate in one! He has to keep checking. 41. Qg8+ Kh6 42. Re6+ Kh5 43.Qxh7+ Kg4 44. Rg6+ Qg5 45. Qh3+ Kf4 46. Qf3+ 1-0
