"I remember many years ago I was in the middle of a pair of competitive correspondence games against a well known player (ex chess editor with a well known publisher), and was very surprised to turn up to a Saturday afternoon county match to see several players discussing one of the games, position set up and everything!"

Not good! If you play CC, you have to play for your own interest and accept that such things might happen. One strong CC player published a book about CC and said that Van Oosterom paid GMs to play his games in the 2003 - 2005 world championship. In a team event, one country named its 8 players, but one guy played all the games and told his "team-mates" what to do!

Thanks. Interesting video. At least we now have a name for the defence!

That's usually regarded as the sequence 1.e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5

This is different because 5. Bb5+ can be played and may be best anyway.

Transpositions to other systems with an early .. e5 are possible if White doesn't play this.

A correspondence game of mine has gone 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 e5!?

Do people know this defence? What is it called and has it been played? I suppose it must.

Or possibly IMs
"Do you play chess?"
"Yes, but I prefer a game with a better chance of cheating."

"Or possibly IMs"

Certainly at least one GM.

I am not sure what you are asking, but here are some details of the 978 games that reach the position after 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 e5:
White's most-popular reply is 5.Nb3 (320 games).
White's most-successful reply percentage-wise is 5.Ne2 (75%, albeit from only 18 games).
One game saw a 1933 play 5.Nc3.
Players who have tried 4...e5 include Ivan Sokolov, Vadim Zyjaginsev and Romain Edouard.
Players who have lost on the white side of the line include Alexander Grischuk.

I have a book "Dismantling the Sicilian" by Jesus de la Villa. He gives a game Khairullin - Zviagintsev, Tomsk 2006, won by White and says 5. Bb5 is best.

How many went 5. Bb5+ which is surely the best move since the exchange of light squared bishops favours White here?
