Need something against Qd3 Qxf8+ and only then Bxd3? (or even Qxe5) Looks like the actual best move might be Nd3+

well Qxf8 then Rxf8 so Qxe5 seems better for white

If white doesn't take bait of Qd3 and chooses Qxe5 then answer with Nxf1 Nxf1 xe6 Qxe6 Kh7
then I dunno what for white
then Re8

1...Qd3 2. Qxf8+ Rxf8 3. Bxd3 Nxd3 4. Kd1 and white has won back the exchange, so this likely wasn't black's best sequence.

1...Qd3 2. Qxe5 Nxf1 3. Nxf1 fxe6 and then maybe 4. Qe2, and white has won a piece here, making the imbalance 2 white pieces to a black rook, so again black has made his position worse instead of improved.

And fwiw, I've got Rybka 2.2 at 15 ply giving: -3.34 1...Nd3+ 2. Bxd3 Qxd3 3. Qc4 Qe3+ 4. Kd1 fxe6

For 1...Qd3, it gives at 16 ply: +0.09 1...Qd3 2. e7 Rfe8 3. Qxe5 Nxf1 4. Nxf1 Qd7 5. Be3 Rxe7 6. Qd4 Qf5

For 1...Qd3 2. Qxf8, 18 ply, -1.09: 1...Qd3 2. Qxf8+ Rxf8 3. exf7+ Rxf7 4. Bxd3 Nxd3+ 5. Kd1 Rf2 6. Kc6 Ne5 7. Kb3

Finally, on 1...Qd3 2. Qxe5, 15 ply, 0.00: 1...Qd3 2. Qxe5 Nxf1 3. Nxf1 Rfe8 4. e7 Qd7 5. Qe2 Rxe7 6. Be3.

I know it's all low ply and not that useful, but it does help with the immediate tactics.

I guess then just f6 or better would be Nd3, in any case white ended up taking bait of Qd3 with Bxd3 then Nxd3. Nxd3 has to be countered with Bxd3 then I guess Qe5 to avoid Qe2++ then f6

Well, wouldn't 1...f6 lose to 2. e7?

Either way, 1...Qd3 is a trap line, but black doesn't need to play a trap here to win, especially not a trap that throws away his advantage. So 1...Qd3 is most definitely not the best move for black.

No, in hindsight Qd3 isn't it just ended up working Nd3 I think is the best line

Yeah Nd3 looks fairly crushing. Something simple like Re8 is probably fine too, but Nd3 is the simplest

My first instinct is ...Qh4. This is a position where ...Nd3 is simple and Black has a big advantage, so it probably makes the most practical sense. If I had plenty of time on the clock, I'd study ...Qh4 over for a while. Hmmm, I'll have to study this later. This is a prime example of my tendency to over complicate matters.

I thought about Qh4 for a second too until I realized that White can just take on e5.. Black is probably still winning because of white's lack of development and open king, but it is too complicated IMO

I was talking about ...f6 on move 1.

Also, in this notation, you should give the starting file for the pawn in a pawn capture. That is, in the sequence you give above, xe5 and xf8 are confusing (and I believe incorrect). They should be fxe5 and exf8.

and whats the proper way to represent this Nxf1(Qh4+)

In this notation, you don't need to indicate which piece is delivering the check, simply what's going where and that there is a check. So it would be Nxf1+. This can confuse you at first as it appears that the knight is doing the checking, and when you find that it isn't you have to scan the board to find out what is, but that's the way it's done.

If you want some more info on the notation, wiki is ok: http://en.wikipedia.org/wiki/Algebraic_chess_notation

Or just keep asking questions here, they're no problem.
