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. :-(
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.
Thanks for visit
