[Event "Budapest"] [Site "?"] [Round "0"] [White "Alekhine"] [Black "Von Balla"] [Result "1-0"] [ECO "D02"] [Opening "Queen's Pawn: 2.Nf3 e6"] 1. d4 d5 2. Nf3 e6 3. Bf4 c5 4. e3 Nc6 5. c4 Nf6 {5...Qb6 6.Nc3 White offers Black a poisoned pawn and if it's accepted: 6...Qxb2 7.Nb5 then the White knight penetrates the Black camp at c7. While Black's queen is almost trapped.} 6. Nc3 cxd4 7. exd4 Ne4 {This premature attack is wrong especially so as White is ahead in development. 7...Bb4 8.Bd3 dxc4 9.Bxc4 O-O Completing his development would give Black a playable game.} 8. Bd3 Bb4 9. Rc1 Qa5 10. Qb3 dxc4 11. Bxc4 g5 {This move is the logical follow up to Black's previous play. However, this advance will make it unsafe for Black to later castle on the kingside.} 12. Be3 g4 13. Ne5 Nxe5 14. dxe5 Bxc3+ 15. bxc3 b6 {15...Qxe5 16. Bd4 Qf4 17.Bb5+ Bd7 18.O-O when White's huge lead in development would give him a winning initiative.} 16. O-O {16.Bb5+ Bd7 17. Bxd7+ Kxd7 18.O-O would also be very good for White due to the exposed nature of the Black king.} 16... Bd7 17. Rfd1 { White decides upon a sacrifice which will leave the Black king undefended.} 17... Ba4 18. Qb1 Nxc3 {18...Bxd1 19.Bb5+ Ke7 20.Qxe4 with a winning attack. For example, 20..Qxb5 would allow White to win material.} 19. Rxc3 Qxc3 { 19...Bxd1 20.Bb5+ Kf8 21.Bh6+ Kg8 22.Qxd1 With a mating attack for White.} 20. Bb5+ Bxb5 21. Qxb5+ {Black's disregard for his development has allowed White to build a mating attack.} 21... Kf8 22. Bh6+ Kg8 23. Qd7 {Black resigned.} 1-0
