You did it wrong! You're only supposed to apostrophize the E in a past tense, all caps, one-word-normally-ending-in-ED post. Don't you know the rules? 😛

RUL'S? What RUL'S?

I RUL'S, and you DRUL'S! 😕

We both DRUL'S compared to this PG:

S. Hashimoto

PG in 9.0 moves

This achieves the theme of your last PG plus the theme of mine, and does it all in less moves!

Any hints to solve this sort of proof game?

1. e4 e5 2. Bc4 Bc5 3. d3 Ne7 4. Bg5 O-O 5. Bxf7+ Kh8 6. c4 Be3 7. Nc3 c5 8. Rc1 Nec6 9. Be7 Bh6 10. Rc2 g5 11. Bg6 Rf5 12. Qc1 Bf8

Finding 2. ... Bc5 was the most work. For too long I was stuck on 2. ... Bd6.

The doubled pawn on f6 is an excellent hint. White's pawn can't get there on its own, so it promoted. There's not many promotion schemes that fit the bill.

Yes that was the only clue there was, that's why I asked. It seems problems in which more pieces stand on another square than their starting square, are somewhat easier to solve. But who am I, I haven't solved 5 PGs in my life!

Aww... I haven't been here since my last post, and I didn't get to try the 9 move game 🙁
