In Queen's Gambit Declined, Albin counter-gambit, Lasker trap, black ended up with three knights, which should be rare. Here white should not capture the additional knight in the next move (8. Rxg1 Bg4+ and black is winning). Are there any other openings that one side ends up with three or more knights?

As @JossieCalderon pointed out, any opening could end up with three knights for one side. This would always require a knight promotion of some sort. Usually, knight promotions occur to

  1. Give check to the opponent immediately to move the king to another square or to save a tempo.

  2. Avoid a knight fork from the opponent, or give one of your own

  3. Avoid stalemate

  4. Give checkmate

I think, however, that you are also asking if there is another opening where knight promotion occurs in the opening phase of the game. The answer is most likely "no".

Theoretically, any opening can allow you to end up with three knights, provided that you promote enough pawns.

    I think that the OP is asking if there is another *known* line in which one side has three knights. – Qudit Apr 18 '19 at 22:20
