My God, two geriatrics from the 20th Century slug it out !

4. c3

4. b4 would be the Evan's Gambit

4... d6

a passive line that should lead to a White advantage. But Stewart is too busy to study chess openings.

4... Nf6 is the obvious move and the main line. However Stewart's knowledge of chess openings is minutely small !

less ambitious than Nc3

7. Nc3 is considered best - Possibly Roger doesn't know much about this line either ! 7... Nf6 8. O-O Bxc3 (8... O-O 9. Bg5 Bxc3 10. bxc3 h6 11. Bh4 Bg4 12. Qd3 is good for White.) 9. bxc3 Nxe4 10. d5 Ne7 11. Qd4 Nf6 12. Bg5 is a good advantage to White.

7... Bxd2+ 8. Qxd2

8. Nbxd2 is normal - the Queen often goes to b3. 8... Nf6 9. O-O O-O 10. Re1 with the better centre.

8... Nge7

8... Nf6 9. Nc3 O-O looks more natural (and play against e4.) 10. O-O Nxe4 11. Nxe4 d5 12. Bd3 dxe4 13. Bxe4 White is slightly better.

9. Nc3

White has an obvious lead in development and the better centre.

9... a6

Stewart considered this Q-side expansion plan his brilliant new concept -contribution to the Giuoco Piano ... (garbage - Geoff)

9... O-O has two games on my database - both won by White.

10. O-O

10. a4 White could have snuffed it anyway !!

10... b5 11. Bd3 Bg4

Stewart believes Bishops should go to g4 or b4 and chop off Knights! How many times have I seen him do that ?

12. Bc2

12. Ne1 is very interesting 12... Nxd4 (12... O-O 13. f3 Bc8 14. Nc2 and White is better.) 13. Qg5 White is better.

12... Bxf3 13. gxf3 d5

With the King in the centre and poorly developed this looks quite suicidal for Black, but it is better than it looks,

13... O-O and Qd7 - h3 looked safer.

14. exd5

Opening up the centre in this way is the logical way to refute Black's play.

14... Nxd5??

Stewart blunders

This is a blunder that should lose the game.

14... Na5 is better followed by Qd6 and Rd8 etc.The pawn is better captured later, after castling. 15. Be4 Qd6 16. Qc2 Rd8 is approximately equal.

15. Nxd5 Qxd5 16. Be4

Too eager, Roger should have considered the check first.

16. Rfe1+ is the move that Geoff thought won easily (....it does !) 16... Ne7 (16... Kf8 (16... Kd7 defending the Knight is Black's only chance, but then 17. Be4 Qd6 18. Qg5 is an extremely nasty move threatening Rc1, Bf5+ etc. 18... g6 19. Rac1 It's find a move time ! Black is busted, his King caught with his pants down.) 17. Be4 Qd6 18. Qc3 Now Nxd4 (as in the game) doesn't work - Black is floundering.) 17. Be4 ouch!!

16... Qd6 17. Rac1

Doesn't work has Black has the tactical get out...

17. Qg5 is the best move 17... O-O 18. Qf5 g6 19. Qc5 White is a little better.

17. Qc3 Nxd4 and the Rook cannot be taken as 18. Bxa8 Ne2+ 19. Kh1 Nxc3 Black wins.

17... Nxd4

It is doubtful if Stewart saw this when he played 13...d5 ..He was just lucky, and it's better to be lucky than good !

18. Rfd1 Rd8 19. Qe3

A weak move, now Black can simply castle.

19. Bc6+ is Roger's best chance, but I believe he was psychologically beaten at this stage. 19... Nxc6 20. Qxd6 cxd6 21. Rxc6 White will regain his pawn.

19... O-O 20. Rc2

Another blunder - White realises that he has missed his chance. He is now in time trouble.

20... Nxc2 21. Bxc2

And Black won.

0-1 [Geoff Peake]
