Qxa4 { Komodo is happy to play a line where it bags the two bishops, even at the cost of a slight weakening of its pawn structure. This displays its increased positional awareness which is one of the things that the developer of Komodo, Larry Kaufman, wanted to focus on. He said that he was even willing to sacrifice some calculating strength in order to maximise the program's strategic understanding.} Qe8 $1 {A typical computer move, in the sense that it looks ugly but somehow just works. I think it was Peter Leko who said that working with computers changes the way you look at chess, because you have to analyse moves that in the past would have been dismissed as too ugly. Now whether the move is aesthetic or not hardly matters, the point is whether it works or not. Black freezes the development of his rook on f8, but has ideas of perhaps playing ...f5, and bringing the queen out to g6 or h5, starting an attack. And in a concrete way the black queen is shadowing my own queen on a4, which becomes relevant very quickly.} 15. d4 $2 {The mistake comes quickly. Normally when you make an error, the computer flashes up a message along the lines of 'Uncle Komodo doesn't think much of your last move buddy' with an option to take back. Then I'll input an alternative which will be equally bad, meeting with a similar reply of 'Komodo thinks that your previous move wasn't the best in the position, Danny' with the effect of further demoralising the patzer user.} exd4 16. cxd4 d5 $3 {I'm not sure this quite deserves two exclamation marks, but it did make a big impression on me at the time. Many carbon-based life forms might subconsciously overlook this idea altogether as it just seems too dangerous for Black to open up the e-file with the rook on e1 and the queen on e8. However, this just works and as soon as you see this move it makes total sense. Now I can't avoid the opening of the position when the two bishops will start to rule supreme.} 17. e5 ({After} 17. exd5 Nb4 {, Black will quickly recover the pawn with a dream position to boot.}) 17... Nb4 18. Qb3 Qb5 {. Black is starting to take control. I can't recall the rest of the game, but I don't think it took long before my position collapsed altogether. This was a recurring theme. Even with White, it was difficult to get past move twenty without a lost position. You'd play what you think was a reasonable game, believe that the position was fairly unclear, then switch on the evaluation and see that the computer was showing '+1.5' in its favour and with that rising all the time. --- I was thinking surely I'm a grandmaster, I should be able to put up some resistance? But all I could think was that Komodo was extremely good at exposing just how poor my chess had become. Of course, computers are scarily strong now. Even the best players in the world would struggle to play against them, but I was getting outplayed on almost every move. It was a daunting experience and hardly the confidence booster I needed before my next tournament down in sunny Hastings. However, I was determined in any case to take Komodo along and use it for preparation.} 0-1

Nf3 Nf6 4. Nc3 dxc4 5. e4 {I chose this admittedly risky gambit because I felt I had more chance of blowing him away in the opening with something like this. If you use engines a lot in preparation, then it makes sense to play sharply when you can use the computer's great power in calculation. That's why Carlsen is famous for avoiding opening variations that are extremely sharp and where there's a danger he can lose in preparation. He doesn't want to lose to an inferior player who uses computer analysis against him, but rather wants to outplay them with his special understanding.} b5 6. e5 Nd5 7. a4 e6 8. Ng5 $5 {An interesting idea that has been championed by the Ukrainian player Eljanov, amongst others.} (8. axb5 Nxc3 9. bxc3 cxb5 10. Ng5 Bb7 11. Qh5 g6 12. Qg4 Bd5 {is the main line. However, White is not better here and many games have shown that Black has quite serious chances himself by playing ...a5 and ...b4 later on.}) 8... h6 $1 ({In my opinion,} 8... Be7 9. h4 $1 {is quite dangerous for Black and} h6 10. Nge4 b4 11. Nb1 Ba6 12. Nbd2 c3 13. Nc4 Bxc4 14. Bxc4 {would have been similar to the line I was hoping to get in the game.}) 9. Nge4 b4 10. Nb1 Ba6 11. Nbd2 Nf4 $1 {This is the problem and makes the whole line somewhat dubious for White. In fact this move has been known about for years. The question was could Komodo find any improvements for White?} (11... c3 12. Nc4 Bxc4 13. Bxc4 cxb2 14. Bxb2 {was the main focus of my preparation. White plays Qg4, castles kingside and eventually puts a rook on d1 with obvious chances of an eventual attack against the black king. By contrast it's surprisingly difficult for Black to free himself without falling apart completely:} Be7 15. Qg4 O-O 16. O-O Nd7 17. a5 {with excellent compensation for the pawn.}) 12. Qg4 Nd3+ 13. Bxd3 cxd3 14. O-O Qd5 15. Re1 Nd7 16. Nf3 {Up to this point this was all preparation.} c5 $1 {Anderson continues to find the best moves. What irritated me at this point was that 16...c5 was clearly the most natural move to play over the board, but in my preparation I had failed to really pay much attention to it.} ({I think the computer was preferring to play some weird stuff like} 16... Bc4 {, but for a human it makes much more sense to open up the position for the two bishops.}) 17. dxc5 $6 {This was where I finally deviated from the engine. I couldn't recall at the board what it had been suggesting.} (17. Nd6+ {was what it wanted to play when I checked the game with it later.} Bxd6 18. exd6 c4 {was what I didn't like at the board as I thought these pawns were starting to look very scary. Of course, though, the computer doesn't fear ghosts and thinks White is doing very well after} 19. Qxg7 O-O-O 20. Qxf7 c3 21. bxc3 bxc3 22. Qxe6 Qxe6 23. Rxe6 d2 24. Nxd2 cxd2 25. Bxd2 {, as he already has a number of pawns for the piece. Over the board, this all seemed too scary, but the problem was the alternative was even worse.}) 17... Nxc5 {Now the knight is targeting b3 and I'm probably just in trouble.} 18. Nd6+ Bxd6 19. exd6 Nb3 20. Bf4 Nxa1 21. Qxg7 O-O-O 22. Rxa1 d2 $2 {Around about here Black starts to throw away his advantage.} (22... Kb7 $1 {was a very strong plan, trying to relocate the king to a8 where it's completely safe:} 23. Qxf7+ Ka8 {and next move Black will play ...Bb7 and start a counterattack of his own. I think White is in big trouble here.}) 23. Bxd2 Qxd6 24. Qxf7 Rd7 25. Rc1+ Kb7 26. Bxb4 Rxf7 ({Of course, the engine spots} 26... Qxh2+ $1 {instantly. We both missed this during the game, although White would still have some chances to hold the resulting ending.}) 27. Bxd6 Rd8 $2 (27... Rd7 $1 28. Be5 Rc8 {was much better. }) 28. Ne5 $1 {I think Anderson had missed this. Now he can't easily exchange rooks anymore.} Rg7 29. Bb4 (29. Bc5 $5 Rd5 30. b4 $1 {is another clever tactical idea that the computer points out. That said, I doubt it is really a winning attempt: for example,} Rxe5 31. Bd4 Rgg5 32. f4 Rd5 33. fxg5 Rxd4 34. b5 Bxb5 35. axb5 hxg5 {with a drawn rook and pawn ending.}) 29... Rd5 $6 { Failing to call my bluff.} ({After} 29... Rd4 $1 30. Bc3 Rxa4 {, White has no good discovery with the knight on e5.}) 30. Bc3 Rc7 31. Re1 Bc4 32. f4 ({After the game I was kicking myself for a number of stupid things I did in this ending, not least of which was 'why didn't I just play} 32. a5 {- ?'. I was concerned that Black might move the bishop away from c4, take on c3 and then take on a5, when I might have problems dealing with his passed a-pawn. However, for one thing White would have dangerous threats of his own on the kingside and, secondly, it would be psychologically very difficult for Black to make this decision to sacrifice given he's had this extra exchange for almost the entire game. This was the first sign I was starting to get nervous and lose my objectivity.}) 32... a5 33. Kf2 Bb3 34. g4 $2 ({Around about here I began to get a very obvious rush of blood to the head. My first instinct was to play the obvious} 34. Ra1 $1 {, protecting the pawn. Then I think I'd actually have very good chances to win the game as Black's rooks are not very effective and he lacks an obvious point of attack. White, by contrast, has a simple plan of expanding slowly on the kingside. All this I sensed during the game, but in mounting time trouble I suddenly lost my head. --- The fact that I sensed Anderson was starting to lose the thread of the game and that White was now better led me to completely lose my objectivity. I thought why don't I just throw all these pawns at him and see what happens? Who cares about a pointless a-pawn which is doing nothing on the queenside? Those were my rushed thoughts at the time, but I still had enough time to think things through.}) 34... Bxa4 35. g5 hxg5 36. fxg5 Be8 37. g6 a4 $1 {This was the point I had missed. By simply pushing this pawn Black does indeed create nasty counterplay on the queenside, which I have great problems dealing with.} 38. h4 a3 39. bxa3 $4 { With 40 seconds left on my clock, I panic completely.} ({The move my hand wanted to play was, of course,} 39. h5 $1 a2 $1 40. h6 Rxc3 41. bxc3 Rxe5 {. My calculation stopped here as I assumed White must be lost, but the engine points out a beautiful study-like draw with} 42. Rxe5 a1=Q 43. g7 $1 {(the only move, but easily sufficient)} Qb2+ 44. Re2 Qb6+ 45. Re3 {. With more time on the clock I might have found this idea, but with so little time left it's almost impossible.}) 39... Rxc3 40. g7 Rd2+ {. So my first real experience of preparing with Komodo ended in near total disaster, although that wasn't the machine's fault. Only when I was forced to think for myself did the old human frailties come to the surface. For my next game with White I tried to make this whole Geller Gambit work, but it just seemed too risky. Besides Keith Arkell seems to be playing at 2600 strength these days just by outplaying people positionally, so why couldn't I do the same? Indeed, I my next game I chose rather than 5 e4, 5 a4 Bf5 6 Nh4 and won a long game.} 0-1
