Blundering in Time Trouble

1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.Nc3 Bb4 5.O-O O-O 6.d3 {Both White and Black are content to develop.} d6 7.Bg5 Be6 {Black, however, is not copying White. He merely hopes to get out his pieces.} 8.d4 {8. Nd5!, piling on the pinned knight, was more precise.} exd4 9.Nxd4 h6 10.Bh4 {White retreats. If Tarrasch plays 8. Nxc6?, Lasker replies 8…bxc6 9. Bxc6 hxg5 10. Bxa8 Qxa8, wherein he has an advantage because of his activity.} Ne5 11.f4 Bc5 12.Bxf6 {Of course, if fxe5, dxe5, and Black regains the piece.} Qxf6 13.fxe5 Qxe5 {Now the pin is awkward for White.} 14.Ne2 Bg4 15.Rf3 Bxf3 16.gxf3 f5 {Lasker aims at the weakened kingside.} 17.Qd3 c6 18.Bc4+ Kh8 19.Kh1 {A mistake. 19…fxe4 now wins: after the trade of queens, Black has a very good endgame.} b5 20.Bb3 fxe4 21.Qxe4 Qxe4 22.fxe4 Rae8 {Rf2 is better: occupy the seventh!} 23.Nxc6 Rxe4 24.Ng3 Ree8 25.Rd1 Rf2 26.Nd4 {And here, in time trouble, Tarrasch blunders from an equal position. He cannot recapture due to 27…Re1+.} Bxd4 {Tarrasch resigned.} 0-1

1. d4 d5 2. Bg5 {If the Black knight doubles, the bishop may now chop it off.} h6 3. Bh4 c5 {Black will eventually regain the pawn, and gains a freer position by temporarily sacrificing it.} 4. dxc5 g5 5. Bg3 Bg7 {The Black bishop has an immediate impact, forcing the move of the c-pawn.} 6. c3 {If the knight had moved, Black plays Bxc3, tripling the pawns.} Na6
7. Qa4+ {White maneuvers to eliminate hang on to the pawn temporarily.} Bd7 8. Qa3 Qc8 9. c6 {White pitches the untenable pawn to hopefully disrupt Black’s development.} Bxc6 10. Nd2 e5 {Black now stands a little better, having superior development and better control of the center.} 11. e4 Ne7
12. Ngf3 f6 {On the other hand, Black’s pieces are a little discombobulated, and the weakened white kingside squared and bad kingside bishop help White to perhaps gain the edge.} 13. exd5 Bxd5 14. Bb5+ Kf7 {Black defers any attempt at castling and prefers to develop the rooks while keeping the king a sweeper-keeper, helping out with its own defense.} 15. c4 Bc6 16. O-O Rd8
17. Rad1 Qd7 {This looks dangerous at first, but knight discoveries are innocuous.} 18. h4 {White tries to break open the Black kingside.} g4 {Black closes the kingside, hoping to close down the flanks to bring his central control to greater prominence.} 19. Nh2 Qd4 {19…f5 is better, solidifying the pawns simply and relieving the queen of its pawn-protecting duties.} 20. Rfe1 h5 {This is a bit worse than f5 because it doesn’t help with the center.} 21. Nhf1 {White redevelops.} Qc5
22. Qa4 {White avoids the trade to avoid either centralizing the Black knight or doubling his own pawns.} Bxb5 23. cxb5 Qb4 24. Qc2 Qxb5 {Black has finally regained the pawn–and another pawn to boot! However, his weak kingside may cause him trouble.} 25. Nc4 Qc6 26. Qb3 Kf8
27. Na5 Qc7 28. Qb5 {Black, with accurate play, has neutralized any White play, remaining a pawn up.} Qc5 29. Qb3 {White resigned immediately after hanging the knight.} 0-1

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bc4 Qb6 {An early queen move made to displace the knight.} 7.Nb3 e6 8.Bg5 {In my opinion, 8. Be3 made more sense, developing with tempo.} a6 9.O-O Ne5 {The knight may now, though in good position, become a target for an f-pawn push.} 10.Be2 Be7 11.Kh1 O-O 12.f4 {White indeed pushes the f-pawn, controlling the e5-square.} Ng6 13.Bh5 Qc7 14.Bxg6 hxg6 {Black takes back with the h-pawn so as to go towards the center, which is generally better than opening up the f-file for his rook.} 15.Qe2 b5 16.e5 Ne8 17.Bxe7 Qxe7
{White now has better control of the center, and better piece harmony. However, Black may soon untangle.} 18.Rad1 Bb7 19.Na5 d5 20.Qe3 Qc7 {Black has now, to a great degree, freed himself.} 21.b4 Bc8 22.Nb3 {However, White now owns the c5-square, giving him an edge. The now-fettered Black bishop also contributes to White’s advantage.} f6 23.Nc5 g5 24.Ne2 {Now, best for Black is a5, striking against the White control of c5.} gxf4 25.Nxf4 Qxe5 26.Qh3 {White now has a gigantic advantage, with all the play and about to win another pawn-the one on e6.} Qf5 27.Qb3 Qe5 {Best for White is now 28. Nfxe6, which works due to 28…Bxe6 29. Rfe1.} 28.Rde1 Qd6 29.Nfxe6 Bxe6 30.Rxe6 Qd8 31.Nxa6 {White is clearly now dominating.} Rf7 32.Rfe1 Nc7 33.Nxc7 Rxc7 {Black has been allowed to trade knights, but White’s heavy pieces are now in even better position.} 34.h3 Kf7 35.Qf3 Rd7 {A poor move in a bad position.} 36.Qh5+ Kf8 37.a3 {37. g4, to finally storm the Black barricades, virtually won immediately.} Rf7 {Black blunders horribly in a very, very bad position. However, as White reached for the queen to mate on h8, plagued by time trouble, he flagged. 0-1.} 0-1
