All but one of my SP518 games as Black started 1.e4, which is also the move I chose in my games as White. In my 'White' games, all but one of my opponents responded 1...c5, which is also my preferred move. That means all but two of my games started as Sicilians (1.e4 c5), and another game transposed to a Sicilian after a half dozen moves. There's no doubt about it. Chess960 opening play is a *lot* more interesting than traditional chess. The difference is between making your own path or following in the footsteps of others.
In the absence of a more substantive post on my part, I'll recommend taking a look at Chess960 Jungle, where HarryO has been naming things: Naming the Bishop Pairs and Naming the Knight Pairs. It's a good idea that merits careful consideration.
Before reading HarryO's suggestions, I had already decided that the best way to classify chess960 openings is the start positions of the Bishops. There are 16 Bishop combinations, with 60 positions per combination. The positions with two corner Bishops (B******B) have much in common with each other, as do the positions with the Bishops in traditional positions (**B**B**). For those who insist on cataloging first moves in all 960 start positions, ECO becomes 'Encyclopedia of Chess960 Openings', with volumes A through P (the 16th letter of the alphabet).
Now I have to get back to researching Sicilians. I hope I'll have time for a more original post next week. In the meantime, don't miss the Military Knights.
