Better Lucky Than Good

Wellington Chess Club's Fischer Random tournament has been deservedly won by International Master Anthony Ker. Anthony beat me in the last round, having earlier dispatched former leader Nic Croad.

This week I annotate my penultimate round clash with Alan Aldridge. Alan took control of the game early on, despite having the Black pieces. He missed winning chances, had me under time pressure, but finally succumbed in the endgame.


The real merit in sharing this game is it shows what happens when you don't put your opponent away. Alan was left with misplaced pieces when his attack ran out.

Alan managed his time quite well, but this is a good opportunity to consider how to play when the opponent is short of time (to the uninitiated, running out of time results in a forfeit):
  • Unless your opponent has a very strong position, don't try to blitz him/her. I'm always amazed, and have been the beneficiary, when a player ahead on time throws the game away by trying to run down the opponent's clock.
  • Play as you would normally. Don't indulge in tactics unless they are at least as strong as any other option. Players in time trouble will calculate forcing lines when it's your turn to move, so by indulging in tactics for their own sake you are playing into their hands. Strong players calculate quickly and cleanly - positional factors take longer to assess.
  • If you have plenty of time use it to find the strongest moves. In addition to improving your position, your opponent who is likely to be running on adrenalin will have difficulty maintaining concentration.
  • Don't play 'safe' moves simply to get the opponent's clock running. Strive to play a good move, even if you consume some of your time advantage. Mediocre play can quickly send your own position downhill and result in...time trouble.

Rapid (25’+5” per move)
Chess960 starting position 943

It’s difficult to play the opening phase in Fischer random accurately, particularly in a rapid game. A technique that served me well in this tournament was to check which pawn if any in the starting position was undefended – in most random positions there is one. I would then focus on this weakness.

In this starting position, as is the case with the classical chess set up, there was no undefended pawn, so I had to find another plan. Opening a diagonal for my white-square bishop seemed as good as any…

(better is 10... fxe4 11. Bxe4 a4 {(Black has the advantage)})

11. e5 {(I thought I was slightly better here, but Alan's turns the tables with his next move, after which I'm defending)} d6! 12. Nf6 {(sacrificing a pawn, but the alternatives just left me worse – at least I've eliminated his black-square bishop that was bearing down on my King)} Bxf6 13. exf6 Qxf6 {(objectively speaking, Black has the advantage)} 14. Nd5 Bxd5 15. Bxd5 Rb6

White to move

(15... a4 {(perhaps a little more accurate - however the rook move played is principled)})

16. Bxc6?! Nxc6 {(Alan spent some time over this move, although he still had more time than me - about 7 minutes to my 4 minutes - we were playing with a 5 second per move increment)}

A Game More Random Than Most

Today's offering is a game from Wellington Chess Club's annual rapid tournament between me and International Master Russell Dive. This was my first over-the-board game of Fischer Random chess, in which both players share one of 960 possible back rank set ups for their pieces. The position, chosen by random, is thus symmetrical...until the pieces start moving and then who knows. The odd thing is that at some point it turns into a regular game of chess.


In my second game, not provided to avoid embarrassment, I lost horribly to Mark van der Hoorn, best known for his predilection for playing the 'Vandalizer'
in 'real' chess, featuring 1.f2-f3, followed by an early Kf2...Kg3...and possibly even Kh4. Perhaps Mark should patent his approach to Fischer Random and call it 'the Randomizer'.

Dark Squares

In Secrets of Practical Chess, John Nunn describes the ideal game as one in which you win without allowing your opponent any counter-chances. From this standpoint, the following game with Michael Nyberg went according to plan, since he is a difficult opponent with an eye for the tactic. I was fortunate to draw the last time we played.

Nyberg, Michael - Njiman, Brian

A game from the 2007 Wellington Chess Club Championships

International Master Anthony Ker and I played this game in the 2007 Wellington Chess Club Championships. The advantage went back and forth, until the endgame when White was forced to sacrifice his knight to stop Black’s central pawns. White’s king was corralled when Black’s king advanced up the board.

Welcome to Capital Chess

I'm Brian Nijman and I live, work and play chess in Wellington, New Zealand. From time-to-time I'll post games, analysis and news, mostly about chess in Wellington.

My playing style is somewhat coffeehouse. My strategic play at times is quite good. I am an A-grade club player with aspirations to improve. I shared first in the 2007 Wellington Chess Club Championships with International Master Russell Dive.

Here is a game you may find interesting:
