1... Qb6+ It's easy to miss this fork-- for White because his last move was to castle, which usually safeguards the King, and for Black, because his own King is vulnerable along the King-file, so he's not necessarily thinking of issuing an attack. Here, castling actually exposes White's King to a deadly check along the a7-g1 diagonal.]

[{A:Bd6f5}{D:1000}{R}{S:d6f5}1... Nf5 On the surface, White has an apparent onslaught against Black's weakened Kingside, but the theory is made ugly by one simple fact -- White's Queen is a goner.  After the Black Knight moves to f5, every square in the Queen's orbit is guarded by Black or obstructed by White.]

[{S:d8g5}{D:1000}{A:Wf3d5}{D:1000}{R}{S:f3d5}3. Qd5# Of course, Black doesn't have to capture the Knight, but if he guards f7 by 2... Qe7 or 2... Qe8, White wins Black's Queen by 3. Qd5+, forcing an unfavorable block on e6. White's Knight then takes Black's Queen, 4. Nxe6. After 2... Qxg5, White also mates by 3. Qb3+, but this takes longer (3... d5 4. Qxd5+ Be6 5. Qxe6#). As a hard-and-fast rule, it's always better to win sooner than later.]

[{A:Wc3d5}{D:1000}{R}{S:c3d5}Question 4 (cont). 2. Nxd5! This steals a pawn, for if 2... Nxf4, White's d5-Knight takes back on f4, removing itself from the line of fire. And if Black takes the knight, 2... cxd5, what is White's follow-up?. Click "Next" for the answer.]

3. Nf6+ Kh8 4. Ng4+ Nxd4 5. Bf6+ Kg8 6. Nh6# Note that 3... Kg7 (instead of 3... Kh8) allows 4. Nh5+ or 4. Ne8+ and mate next. Meanwhile, if Black takes White's queen, 2... Nxd4, then 3. Nf6+ Kf8 4. Bh6# ends resistance.]

[{S:a1a2}{D:1000}{A:Bc3c2}{D:1000}{R}{S:c3c2}Correct. White cannot stop Black from making a new Queen. If White saves his Knight, 3. Nc3, Black promotes at c1. And if White guards c1, say with his King, 2. Kd2, Black promotes by taking the Knight at b1. There's no saving grace.]
