Today we're due an update as to S&BCC's recent fortunes in the Surrey and Croydon Leagues. However, since Tom is currently walking up hill and down dale I've been left minding the shop so we'll put League news on hold for a day or two (sneak preview: we'll be glossing over the Croydon League I's recent trip to Coulsdon).
So what to fill the gap until TC gets his yomping boots off?
It occurs to me that the S&BCC Blog likes nothing more than a pedantic discussion on the definition of some chess term or other. Well my little corner of it doesn't, and judging by the disapproval my use of the term zwischenzug attracted, I am not alone. We might also recall Justin's more scholarly look at Zugwang back in November.
In this spirit, then, who's up for a pointless investigation into what a combination actually is?
Thumbing through an old Batsford book just before Christmas (Yakov Neishtadt's "Test Your Tactical Ability"), I found the following listed as
"... the essential features of a combination:
1. Coordinated action of two or more pieces.
2. Forced aspect of the variation.
3. Presence of a sacrifice.
4. Positive aim of the operation."
I don't have a problem with 1, 2 or 4 but what's 3 all about?
It seems CJS Purdy shares my doubts and has argued strongly that there's absolutely no reason that a combination has to involve the shedding of material . Edward Winter, in his wonderful book Kings, Commoners and Knaves, quotes Purdy's opinion then follows up with a couple of pages of debate on the question. My favourite argument against Purdy, from one Antonio Gude, is that the example given was not a sacrifice but a "logical tactical sequence". What's the difference I wonder.
Surely, though, a combination is merely the linking together of two or more tactical themes into a single operation? Nothing more, nothing less.
Here's an example from one of my own games to prove the point ...

... Bxf3
(removal of defender)
Bxf3?? Rxe1+
(opening a line)
Rxe1 Qxg5
(win of material).
A combination wouldn't you say? A simple, even trivial one no doubt but a combination nevertheless.
