7.Qd3N
[Why not simply 7.Nxd4 Nc6 8.Nc3= ; or 7.Qxd4!? Nc6 8.Qh4= ?, the latter of which has been played by GMs Mamedyarov, L'Ami & Mednis?]

7...Nc6 8.a3?
Again, recapturing on d4 should have been automatic. Now I hold the P and threaten to win a piece.

8...e5 9.e4 a5 10.Bd2
[>=10.Bg5 d6 11.Nbd2-/+ and White is fully developed.]

10...d6
Even the most conservative engines say Black is already winning. Fritz 12 puts him at a whopping -2.96!

11.Ne1 Nd7 12.a4 Nc5 13.Qa3
[>=13.Qe2 ]

13...Be6
[>=13...Qb6 /\ ...Nb3]

14...Bxc4 15.Nxc5 Bxf1 16.Nxb7
[>=16.Bxf1 dxc5 17.Qxc5 ]

16...Qe7 17.Nxa5
[17.Nxd6 Bxg2 18.Kxg2 ]

17...Nxa5?
[17...Bxg2! 18.Nxc6 Qd7! 19.Kxg2 Qxc6-+ was best.]

18.Bxf1 Rfc8 19.Bb5?
[I expected 19.Bxa5 Rxa5 20.b4 Raa8 21.b5 (-/+ Rybka 3 & Firebird; -+ HIARCS 11 & Fritz). Now my N gets into c4,]

19...Nc4-+ 20.Qb4
[>=20.Bxc4 Rxc4 21.b4 ]

20...Qe6

21.Kg2?
[21.a5 was a much better try.]

21...d5 22.b3?
This loses the Q but White was totally lost, regardless.

22...Bf8 23.Bxc4
Joe could have quit here. At best, he's just going to have a N+P for the lady.

23...Bxb4 24.Bxd5 Qb6 25.Bg5 Ra5 26.Nd2 Bxd2 27.Bxd2 Rxd5 28.exd5 Qxb3
White resigns Time left - Renna 4:21, Moldovan 19:03 Time used - Renna 52:59, Moldovan 38:17 Longest think by White - 7 minutes for 22.b3?? Longest think by Black - 10 minutes for 16...Qe7 0-1
