I’m assuming it’s expecting Qxb5, Nxc7+ with a royal fork. But what’s stopping c6 or Nc6 instead, keeping the black Queen in a position to protect c7?

    c6, Qc3

    1.) xb5, Nc7+ and get their rook (unless they decide to take their queen for your knight)

    2.) xd4, get their queen (so yeah 1. will happen)

      1. You’re basically trading a knight and a bishop for a rook in this case, plus black gets an active center. Dunno if that is a very good trade.

      I cannot find a reason why Bb6 would be brilliant. Just grabbing the center with d4 or castling seems like the better option.

    That’s a sacrifice to create a triple fork. Queen takes bishop, knight takes c7 pawn, forking the king, queen and rook.

    It’s forced, since the queen is pinned initially. Also leaves the knight on that cosy b5 square when you’re finished.

    ITT: Wrong

    Unless I’ve missed something big you are correct; it wins the pawn which is nice, but it’s hardly earth shattering as long as black doesn’t have a brain fart and take the bishop. According to a quick look with Stockfish:

    1. Bxb5 c6
    2. Ba4 Qb7
    3. c3 Nd7 and black has escaped serious consequences
    1. … c6
    2. Qc3 xB
    3. Nc7+ Kd8
    4. NxR Qb7
    5. O-O Nc6 is bad for white, black has two pieces for a rook and change, and most of white’s development has evaporated
    1. … Nc6 is worse for black though
    2. d4 Rb8
    3. Ba4 Ba6
    4. c3 Bb5
    5. BxB RxB
    6. O-O and the attack is over, but black had to scramble to defend and wound up down a pawn with a messed up position

    You can try yourself; go to lichess and click the little live-analysis toggle on the left side up above the move list. Stockfish isn’t perfect but it’s better than any of us here.

      Yeah, Stockfish doesn’t consider it a brilliant move at all. Evaluation swings from +2.6 to +1.6.

      Instead of Bb5, SF recommends grabbing the center with d4 or castling.

    probably because it’s a sacrifice and if they take the bait it’s a triple fork. even if they don’t take the bait it leaves you in a better position. don’t know about the brilliant algorithm of chess.com but it’s probably a move above the player’s level.
