SP141 White to play: 1. e4
The classic scenario simply goes like this:
- e4!? ... f5!? (White screams doohhh! because of Bxa2)
- Nb3!? ... fxe4!?
- f3!? ... Nb6!?
I cannot tell you how many times I have played e4 to find this scenario or similar cropping up! So here are some stats for the scenario and how often to expect it. Notice that the theme crops up in batches of three consecutive SP's in a row? I've included quick computer checks of exactly the same King's Pawn Opening opening sequence from above, noting their approximate severity:
| 285 | NRKBNRBQ dubious
| 287 | NRKNRQBB dubious
- If a rook is on f1 it is dubious for white because of Rf8xRf1
- If a queen is on f1 same as above
- If a queen or rook is on e1 then usually good
- If a knight is protecting a7, then it is dubious for white
- If a knight is on f1 then good
I actually quite like the Chess960 numbering scheme because of the way that themes like this play out in consecutive batches of SP numbers. Makes for interesting studies by consecutive SP numbers.
