Old Indian Defense: Bg5 – Black Seizes the Initiative

The Old Indian Defense is a solid, slightly offbeat choice for Black against 1.d4. By playing 2...d6, you keep a flexible pawn structure while avoiding more heavily analysed lines like the King's Indian or Grünfeld. White's 3.Bg5 looks annoying — it pins your knight and threatens Bxf6, giving you doubled pawns on the f-file. But 3...Ne4 turns the tables. Instead of passively defending the pin, you attack the bishop and ask White a question: will they retreat, trade, or find the best continuation? The statistics show that most White players struggle here — White's score never reaches 48% against any of the five most common replies. You are fighting for the initiative from a position that theory considers completely balanced.

Your opponent's best move — though almost nobody plays it — is the quiet retreat 4.Bc1. Stockfish confirms that after Bc1, White keeps the game perfectly level at +0.00, which favours neither side. The engine's continuation runs 4.Bc1 e5 5.e3 exd4, leading to a symmetrical pawn centre where Black has easy development. Why does 4.Bc1 score well? The bishop returns to its starting square, acknowledging that its early sortie achieved nothing. Meanwhile your knight on e4 is well placed, controlling central squares and ready to retreat to d7 or f6 if needed. In practice this line is rare — most White players prefer one of the more 'natural' moves that actually punish themselves.

Across 6,974 games from this exact position, the results are striking. Black wins 50.5% of the time, White wins 45.6%, and only 3.9% end in draws. That's an exceptionally high win rate for Black in a d4 opening — most lines give White a slight practical edge at club level. Here, Black out-scores White by almost five percentage points. The most popular White response is 4.Bh4 (2,218 games), keeping the pin. But Bh4 is actually a mistake that loses roughly 1.2 pawns of advantage — White would have been better playing Bc1. Next is 4.Bf4 (1,864 games), an inaccuracy costing about 0.7 pawns, and 4.Nf3 (1,417 games), an inaccuracy costing about 0.5 pawns. Every common move except 4.Bc1 gives Black the better chances.

Here is how to handle the three White moves you will face most often in the drill. Against 4.Bh4, White is trying to hold the pin — but your knight is perfectly safe on e4, and you can follow up with ...d5, ...g5, or simply develop with ...Nc6 and ...e5. White's misplaced bishop is awkward and will often be harassed later. Against 4.Bf4, the bishop goes to a slightly safer square but remains exposed. You can play ...g5 immediately, forcing White to decide between moving the bishop again or allowing ...gxf4. Against 4.Nf3, White develops a piece but gives you time to play ...e5 or ...Bg4, creating threats of your own. In all three cases, Black's practical score is above 50% — you are already playing for a win from a position the engine considers equal or slightly favourable.
