Caro-Kann Defense: Hillbilly Attack, Schaeffer Gambit: what should Black play?

In the Caro-Kann Defense: Hillbilly Attack, Schaeffer Gambit (ECO B10), Black faces an immediate threat against the f7 square. The engine's top recommendation is g6, which parries the mate threat while attacking the queen, yielding an evaluation of -0.77. Resolving this tactical skirmish correctly is vital, as careless development allows White a dangerous attack on Black's king.

Defending the f7 square with g6 or e6

Black primarily relies on two pawn moves to neutralize White's battery. The most common choice is g6, played in 49.8% of recorded games (143K recorded), where White scores 55.6%. An illustrative engine continuation follows g6 Qe2 Nf6 Nc3 Bf5 f3, where Black holds an extra pawn while White attempts to contest the center. Alternatively, e6 is chosen in 36.5% of games (105K recorded) with an evaluation of -0.71 and a 52.7% White score. Play can continue along e6 Nc3 a5 Nxe4 a4 Bc4, securing the king at the cost of blunting Black's light-squared bishop.

Tactical traps and common mistakes

Failing to directly address the battery on f7 leads to severe trouble. The natural-looking developing move Nf6 is a major tactical error evaluated at +2.37, yet it occurs in 12.1% of games (35K recorded) where White scores 57.2%. The engine demonstrates White's decisive advantage in Nf6 Qxf7+ Kd7 Nc3 Qe8 Be6+, stripping Black of castling rights. Similarly, the passive king step Kd7 yields an evaluation of +2.40 and leads to Kd7 Qxf7 Nf6 Nc3 Qe8 Be6+. Defending with the knight via Nh6 avoids immediate ruin and evaluates at +0.00 across 1.6% of games (4.5K recorded), proceeding with Nh6 d3 g6 Qe5 f6 Qxe4, though g6 remains the cleanest path to an advantage.
