Chess Opening: Lasker’s Trap
A discussion of Lasker’s Trap, which shows up in the Albin Countergambit to the Queen’s Gambit. I had to use WinBoard for this lecture because PGNMentor does not allow me to promote my pawn to a knight.

@GreenCastleBlock Here is the best I could do with it: 5. Bd2 dxe3 6. fxe3 Qh4+ 7. g3 Qe4 8. Qf3 Bxd2+ 9. Nxd2 Qc2 10. Bh3 Nc6 11. Bxc8 Rxc8 12. Qg4 Nge7 13. Qxg7 Rg8 14. Qf6 Rg6 15. Qh8+ Kd7 16. Qxh7 Qxb2 17. Rd1 Nxe5 18. Qh5 f5 19. Ndf3+ Rd6 20. Nxe5+ Qxe5 21. Qe2 Rxd1+ 22. Qxd1+ Ke8 23. Qd4 Qa5+ 24. Qd2 Qa3 25. Kf2 Rd8 26. Qc2 Rd3 27. Qe2 Ng8 28. e4 f4 29. Qh5+ Kd8 30. Qg5+ Ne7 31.

after Qe4 during the line where white puts his bishop on e2 to block Bb4+ what do you play if white goes N(g1)-f3
Comment by welshnick300365 — July 28, 2010 @ 3:49 pm
@duskwalker2 I don’t agree that White can get any advantage against 4…Bb4+. All the lines are miserable for the first player.
Comment by GreenCastleBlock — July 28, 2010 @ 3:55 pm
I ran the 5 possible moves for White after 4…Bb4+ through the analyzer on Babaschess to a depth of 12 moves ahead, with the following results:
5. Bd2, White advantage 0.40 points
5. Ke2!?, White advantage 0.05 points
5. Nd2?!, Black advantage 0.17 points
5. Nc3?, Black advantage 3.72 points
5. Qd2??, Black advantage 5.69 points
1 pawn = 1 point, roughly speaking.

what if the pawn doesn’t go to e3 but jumps up two?
Comment by suprhavkdogi — July 28, 2010 @ 4:35 pm
Great chess video, I love those rare tricky situations in chess where underpromotion is the key to success! I guess I will study Albin’s countergambit soon
Comment by swordstick — July 28, 2010 @ 5:25 pm
1:33 i like the way you pointed out knight is pinned
Comment by mobbinthrudabay — July 28, 2010 @ 5:38 pm
@WizlBs I know that if White takes the bishop, black recaptures, and white takes the queen with his knight, that black can fork the king and rook. However, you can play a3, force the bishop-knight exchange, but lose a pawn
Comment by Zelrio28 — July 28, 2010 @ 6:24 pm
Ok. And after black plays Nc6 what then? There is a still treat on white rook. One of the moves to continue would be taking bishop, but than black can take your rook and kings side is crushed
Comment by WizlBs — July 28, 2010 @ 7:16 pm
After Qe4 at 1:38 just let white play Qa4+
Comment by Zelrio28 — July 28, 2010 @ 7:55 pm
what if in the bishop blocks after the queen check what if the knight blocks on f3
Comment by sutomaraj — July 28, 2010 @ 7:59 pm
Nice video the same day I saw it I got to use it in my bullet game. The game went like this 1. D4 D5 2. C4 E5 3.DXE5 D4 4. NF3 NC6 5. E3 BB4+ 6. BD2 DXE3 7. BXB4 EXF2+ KXF2? QXD1 and he resigned.
Comment by ftwsibbaftw — July 28, 2010 @ 8:03 pm
Sorry, I don’t know why I said f6. I meant to say 4. Nf3.
Comment by Achilles94627 — July 28, 2010 @ 8:04 pm
You’re correct in that this trap only applies to 4.e3?
4.Nf3 is the main line of the Albin Counter Gambit. 4.e4 is another possible move. Against either of these I would play …Nc6 and just develop my pieces, using the pawn on d4 to constrict White’s development… in theory. I have a couple other videos on this channel of me using this gambit, although I’m not sure of its overall soundness.
Comment by GreenCastleBlock — July 28, 2010 @ 8:42 pm
As you say, it does depend on White playing e3. He may just as easily play f6. What do you do then!?
Comment by Achilles94627 — July 28, 2010 @ 8:59 pm
nop, white pawn take (g7xNf6)
Comment by maxamix1 — July 28, 2010 @ 9:53 pm
no, the pawn can take it if hte rook tries to check, that also allows whites rook to not be pinned and get out of the corner. bad move.
Comment by haneyw — July 28, 2010 @ 9:54 pm
i know i just confuse them sometimes, or perhaps it was very late when i wrote the comment, dont know
Comment by rulo0801 — July 28, 2010 @ 10:16 pm
