Hello,

I was reading through Albin Countergambit. and came across Lasker's trap.
My question here would be, here after underpromotion of pawn to Knight, why would white move its king, instead why cant he take the knight by rook ???

Thanks

I think you'll have to post the position so we all know what you're talking about.

"Wikipedia" to the rescue... Lasker Trap - Wikipedia, the free encyclopedia

If White takes the Knight with the Rook then Bg4+ wins White's Queen.

Something is wrong with the position- Black has 3 Knights.
Give all the moves.
For a discussion on Lasker's Trap go to:
YouTube - Chess Opening: Lasker's Trap

That's not wrong, Malbase. Black promoted a pawn to a knight. Check out the Wikipedia link that FinFangFoom included with his diagram.

After 1.Rxg1 Bg4+ is devastating. Winning, even

Albin Counter Gambit:
Fine indicated in 1948 that 4. e3?
1. d4 d5 2. c4 e5 3. de5 d4 4. e3? Bb4+ 5. Bd2 de3: 6. Bb4?? ef2 7. Ke2 f:g=N+!++
(or 6. Qa4+ Nc6 7. B:B ef2+ 8. Kf2: Qh4+)
Are there any examples of actual games: Lower rated yes-
See Chesslive.de. About 19 games from 1959 to today.
Other tries: 4. a3 Nc3 5. e3 Bf4 -See Cohn - Wolf Munich 1900. The game was drawn eventual, but Fine indicated 4 a3 is inferior. Chesslive.de has
210 games in the database starting with Johnston - Marshall, F. 1899
One of my Chess computers kept playing the Albin. I asked Chessville for advice, and was given avoid playing e3.
Fine gives 4. Nf3 as the correct response.

Lasker played against the Albin: against Albin at NY 1893.
As Black, Lasker played the Albin against Hodges at Cambridge Springs 1903. Another example, Lasker as White, Alekhine played the Gambit against Lasker at St. Pete 1914. The Gambit was not played.
Wikipedia gave a consultation game against Lasker (Black) 1899.
Kordy -Bologh went from the base trap game: 8. Rg1 Bg4+ 0-1 )1931
Chessgames.com has more than several examples with a later example:
Shatkin-Bauer. Shatkin went 7. Kf2 Qxd1 0-1 1960
