What are the odds?

We discussed odds-giving last Friday - that is, starting without one or more of your pieces.

I mentioned one of my favourite Lasker stories, where he teased a player who didn't know hime, which I quote from Chernev (1948):

The six basic tactics

Here's eight of them!

The different types of tactic are:

  • jumps (discovery)
  • mates
  • forks
  • pins/skewers
  • nets
  • ties (undermining and overloading)

Here's one of each:

A Queen sacrifice

I played an extremely boring last-round game at Torquay, choosing the English Defence, which is usually good for a scrap at my level.

Archer-Lock,C - Regis,D Torbay Open Riviera (5), 20.11.2011

1.d4 e6 2.c4 b6 3.Nc3 Bb4 4.e4 Bb7 5.Bd3 f5 6.Qh5+ g6

The Queen check is supposed to weaken the black King's-side, but it also has some benefits for Black; f5 is strengthened and the g7 square can be a bolt-hole for the black Queen.
