Hi everyone, it’s Jerry. The Lasker Trap is
a trap for black out of the Albin Counter Gambit. In it, white can easily fall victim
to an extremely rare and devastating tactic involving a mere pawn. Let’s see how this
black d-pawn in particular could turn out to be very deadly, and along the way pay close
attention to this queen h4 move as it’ll be present in the few of the sub variations
I show. So after d4, d5, and c4 the Queen’s Gambit. With e5 we have the Albin Counter
Gambit. d takes e, and d4 robbing the queen knight of this c3 square. Now a very common
idea is to challenge an opposing pawn that’s in your territory with one of your own pawns.
The move e3 does just that, however in this instance it’s already a step in the wrong
direction for white. Bishop b4 with check, and after the counterattacking bishop d2,
this threat against the bishop is one that black can ignore with d takes e. And before
I get into the type of beating white will end up taking if bishop takes bishop, let
just point out that the best continuation for white is to immediately recapture on e3.
And should that come about, here’s how black can at least regain the material lost. Queen
h4 with check, and after g3, queen e4. And pay particular attention to what exactly the
queen is doing…not only hitting the rook and the pawn on e5, but also the one on e3.
Keep in mind the bishop is pinned, and in short, material…the pawn, will be won back,
and black is doing quite alright. Reverting back to this position…if instead of f takes
e, queen a4 were played, we would have the knight blocking the check. And after bishop
takes bishop, pawn takes pawn would ensue. King takes pawn, and yet again queen h4 with
check. Pawn g3, queen to d4 with check, and however you slice it…no matter where the
king goes, the h1 rook…the a1 rook will fall. For example if king to g2 or e2, it’s
queen takes b, and then queen takes the rook on a. If the king runs home, we have queen
e4, and it’s the rook on h1 that falls. And lastly, if king f3 we have bishop check, king
g2, queen e4…the rook on h1, yet again, will fall. Finally, what occurs after bishop
takes bishop from this position is pawn takes pawn with check, trying to deflect the king
away from defense of the queen. King to e2 is the only way to maintain defense of the
queen. But now comes the devastating pawn takes knight, under promoting to a knight
with check! This is all very important as otherwise capturing the knight and promoting
to a queen allows white one moment to breath. And in that moment, there’s queen takes queen,
king takes queen, and only then the recapture and the material is balanced. However, under
promoting to a knight lands a check. And now after rook takes knight, we would just have
bishop g4. This is lights out…the queen is dead. And the other line would be king
e1, and now yet again, queen to h4. If g3, we have queen to e4, and the rook is dead.
And if king to d2, we have a tricky knight coming out with tempo, the bishop coming out
screaming down at the queen, black queenside castling giving a check to the king, and not
to mention black is still up a piece.
