The puzzle is of the old fools mate I use to play a long time ago.

Some of the games are good,and some have a lot of mistakes!

...jrmrbr...1. e4 e5 2. Qg4 Bc5 3. Nf3 Bd4 4. Bb5 Qe7 5. Qh5 b6 6. Nxd4 exd4 7. d3 Qc5 8. Bg5...Rather than why does 12..NC6 ... 12. Qxb5!

I see a lot of errors on white behalf @jrmrbr   12 should be fxe2?

This opening is good in the way that your queen and king side bishop can get onto the board early, but leaves your king vunerable. Between king's pawn and queen's pawn is tough as they both let your bishop and queen onto the board.

D4 is statistcally a better move simple because of the C5 move that black can make to counter it. 

my fav move, and I open it every time!

great move anyway :)

Hey master_mitchell, where did you hear that d4 is better?

This move works well and I use it, however, statisticaly d4 is better.

why is it checkmate? i dont understand

I practice this a lot...success winning 100%

This is the only opening I know! hahaha Although that'll change.....I guess it's all a matter of how much you love the game to know how much you'll "PRACTISE" it!.....
