1. d4 d5 {Not a promising opening for a checkmate in less than 20 moves, but I know my opponent, and this time I'm really going for it.} 2. f4 {I'm not very good with QP openings, but I can't imagine this is a good move in any universe, it blocks in your dark bishop, and opens a diagonal for me to attack your king, also you've weakened your position for kingside castling. it does stop e7-e5, but then your d pawn was doing that already} Bc8f5 {Usually I'd bring knights out first, but as I know my opponent likes pawn moves, I decided to go straight for the throat}3. Ng1f3 {a developing move, ok} Nb8c6 {A developing move, but with the lame plan of Nb4} 4. e3 {Better than the last pawn move, as at least you give your light bishop space to develop, c3 would have been better as it opens a diagonal for the queen and stops.....} Nc6b4 5. Nb1a3 {A Knight on the rim is dim! Put the knight on c3 and you'll see it can reach 8 squares, from this a3 it can only reach 4, so it is half as effective, however, well done on spotting the weakness on c2, I think B-d3 would have been a better defence. It would lead to me either retreating or exchanging off, both a good basic way to diffuse an attack} Ng8f6 {Another developing move, see how I've one pawn move to your ....}6. c3 {....four, 66% of your moves have been pawn moves, and every one aside from the opening move has weakened your defence}Nb4c6 {Forced to retreat} 7. Nf3e5 {That's not a bad place for your knight to be, It's advanced and I can't chase it away with my pawns, but I can just exchange off and double your pawns, had you used your light bishop to pin my knight Bb5 first, then I wouldn't have that option}Nc6xe5 {An even material exchange, but forcing you to double your pawns, also 50% of your developed pieces are taken off, whilst only 33% of mine are taken off} 8. fxe5 Nf6e4 {Now that is a good square - it's called an "outpost", my knight is advanced and can't be driven away with your pawns, even if you take it off later with a knight or a bishop, my bishop will take it's place on the "outpost"} 9. Bf1d3 {That's fine, developing a piece and attacking my knight outpost. But look, things are not going well, maybe you should consider counterattacking, you can check me with your queen or maybe just move her to b3 where she is attacking my b pawn} e6 {Releasing my dark bishop, offering a flight square to my king and most importantly, freeing the queen to threaten check on h4} 10. O-O {Your play would instantly improve if you just concentrated on clearing out the kingside pieces and castling whilst you still had an unmoved pawn wall for the king to hide behind, now it's too late to make much difference.} Qd8g5 {Just moving the heavy artillery up} 11. Na3b5 {Ignoring the growing storm on the kingside, you're offering a threat which is good, but your threat is to win material, and mine is to mate, so i don't even need to respond} Bf5h3{To threaten mate, but also, just because I can. It looks like your g pawn defends this square, but my queen pins it against the king. If there are squares that look like they're defended, but in reality the defending piece cannot move, then they are usually pretty good places to place your pieces, especially at out level.} 12. Nb5xc7 Ke8d8 13. Nc7xa8 Qg5xg2 0-1
At last a game simple enough for me to analyze! The notes are written especially for my opponent who will be joining our chess club in September. I'll start another thread with it on if anyone wants to add anything.
