White should prefer c4 and Nc3.} Nb8a6 {The knight will be active on c5, and we're forcing White out of familiar positions.} 4. a3 Na6xc5 5. h3 {h3 and a3 feel like solutions looking for a problem...} e5 {...d5 was possible too, but then Nf3 would delay ...e5} 6. b4 Nc5e4 {...Ne6 was a good alternative.} 7. Bc1b2 Qd8c7 8. Bf1e2 d5 9. Ng1f3 Bf8d6 10. Nb1d2 {White continues developing, but has a cramped position.} Bc8f5 {Black completes his development. Perhaps his 12th move idea was already possible here?} 11. Ra1c1 {White should consider o-o.} Ra8c8 {With ideas of capturing on c2 after moving the e4 knight.} 12. c4 {Too slow?} Ne4xf2 {A good practical shot, if probably unsound given best defence. Black will draw out the White King and his pieces are better coordinated.} 13. Ke1xf2 d4 {Clearing lines for bigger pieces. I also contemplated ...e4 but thought this was more promising by opening the centre further.} 14. exd4 exd4 {Black still has nothing very concrete...} 15. Nf3xd4 {...but removing the defenders of his King is short sighted.} Bd6g3 16. Kf2g1 Qc7f4 {Threatening both Qf2# and Qe3+} 17. Nd2f3 Qf4e3 18. Kg1f1 Qe3f2 0-1
