Zukertort Opening: Polish Defense as Black
After 1.Nf3 b5, you are choosing a sharp and slightly risky way to fight for space on the queenside. The trade-off is immediate: White is already better, so your job is to understand the ideas, not pretend the opening is equal. This lesson page points you straight into the drill, where you can practise the key position, see how the engine reacts, and learn which continuations cause you the most trouble.

Stockfish rates this +0.81, a clear, lasting advantage for White. That means you are worse here and need practical accuracy right away.
The database confirms the same picture: across 90,117 games at this exact position, White scores 54.6%, draws 4.7%, and Black wins 40.7%. This is not an opening where you can rely on vague counterplay alone. You need to know the most common plans White chooses and be ready to meet them with active piece play.
What the engine wants you to know
The engine's best move here is e4, and the listed continuation is e4 Bb7 d4 Bxe4. The important lesson is simple: White is happy to expand in the centre, and your queenside pawn move has to earn its place.
For you as Black, the drill is about surviving the early initiative and finding useful squares for your pieces. If White gets a smooth central setup, the position can become uncomfortable quickly, so this is a good opening to practise calm defence and exact response rather than wishful attacks.
The moves White chooses most often
The most-played continuations help show the shape of the opening. White's main choices here are d4, e4, g3, Nc3, e3, and b3. The two biggest branches are d4 with 23,543 games and e4 with 20,864 games, both scoring 54.7% for White.
A few other choices also matter: g3 appears in 17,730 games and scores 57.4% for White, Nc3 appears in 6,529 games and scores 51.5% for White, e3 appears in 6,110 games and scores 55.7% for White, and b3 appears in 3,115 games and scores 55.6% for White. In practice, White has several good ways to press, so your preparation needs to be broad rather than narrow.
The mistakes to punish
Two specific mistakes are flagged here. g3 is an inaccuracy and loses about 0.6 pawns; the better move was e4. Nc3 is also an inaccuracy and loses about 0.7 pawns; again, the better move was e4.
For your training, that means you should pay close attention when White chooses either of these quieter developing moves. The opening punishes passivity more than it rewards neat piece setup, so if White delays the central break, you should be alert to seize the moment and keep the game concrete.
