Stream of Chess Consciousness - 2
I started playing and analysing a game in this previous post. I will continue on from the position shown on the left. A replayable board is below.
11.Qd2. Avoiding the discovered attack on my Queen by Nd5 that I missed previously.
11...a6. I was a little surprised by this. I expected Rc8 instead, which must be a decent move, but Hiarcs was still in its opening book so there have to be good reasons for this move. I can only think that it either aims to keep my knight out of b5, or alternatively prepares to play b7-b5.
At this point I tried to come up with a plan and decided that I would try to take advantage of the position of the Black bishop on e6 by playing f4 followed by f5.
Hiarcs was now out of its opening book, so I guess that my last move wasn't necessarily the best.
12...Qc7. I had realised that by advancing my pawn to f4 that my King might be exposed on the open b7-g1 diagonal, so I had expected Qb6+ to which I was happy to reply Kh1 tucking my King out of the way. Qc7 attacks the pawn at c4 again so I played
Fritz tells me this isn't a good idea, even though it seems an obvious move. Black attacks the c4 pawn, I defend the c4 pawn. It prefers Rac1 which develops the rook and indirectly defends the c4 pawn because Bxc4 would lose to various discovered attacks on the Black Queen and pins of the bishop on c4 against the Queen. However, the analysis required to justify such a move is beyond me at the moment - perhaps it always will be!
Creates potential threats along the weakened diagonal. I thought a lot here about whether or not I should exchange off the Knight with my Bishop. I didn't want to do it if I could avoid it, because I didn't want to give Black the Bishop pair. So I checked for danger and decided to play...
14. h3? Qc5+ 15. Kh1
Here I had analysed Nf2+ and decided that after Kh2 my King was safe, there were no more tactics and Black's Knight was virtually trapped. Fritz analysis shows I was wrong - I missed 15...Bxc3 Qxc3 16.Nxe4 winning an important pawn. However, Hiarcs played...
My heart sank at this. My Queen and Knight are both threatened, forcing an exchange of Queens. So much for my plan to attack!
14. Qxe3 Nxe3
Here I should have moved my attacked Rook and defended the Knight at c3 by playing Rfc1. Instead I tried to be clever and decided to attack Black's stranded Knight instead.
15...Rf3? 16. Bxc3 17. Rc1
Now when Black moves the Bishop I planned to take the Knight on e3.
Oops! Missed that completely. Well, actually I think I considered it for a fleeting second and thought I would play Rd1 or Rc2, but of course either of those puts the Rook en prise to the Knight.
Time for another takeback! I don't usually do takebacks, honest! But this is a computer opponent and I am trying to learn. 14.h3 appears to be my first serious mistake so I'll go back to there for my next post on this game.
