The Rat Defense: English Rat, Lisbon Gambit aims to invite early contact in the centre and then ask White to decide how to handle the tension. After the opening moves, the position is already asymmetrical, so piece placement and timing matter more than memorising a long line. As Black, you want to stay active, keep your pieces coordinated, and be ready for White’s most natural ways to resolve the centre. If you understand the position, this can become a practical and flexible weapon.
The critical decision at the board
The engine’s best move here is exd6, continuing exd6 Qxd6 Qxd6 Bxd6. That tells you the central tension is the key point in the opening, and the position often simplifies once White chooses to resolve it. In the drill, focus on recognising that this capture is the main test and on understanding how Black should react after the exchanges. The idea is not to panic, but to meet the central break with accurate development and steady piece play.
What the statistics say
At this exact position, Lichess shows 86,833 games. White wins 44.9%, draws 3.5%, and Black wins 51.6%. That is a useful practical sign: this is not a busted opening for Black, and the position has produced plenty of good results. The numbers also show that White’s most common choice is the engine’s main line, so you should expect that continuation often and be ready for it in the drill.
Common replies and what to watch for
The most-played continuation is exd6, with 71,010 games and White scoring 44.2%. Other common tries are Nf3 with 9,261 games and White scoring 48.8%, Nc3 with 3,453 games and White scoring 50.0%, Bf4 with 638 games and White scoring 49.1%, f4 with 481 games and White scoring 43.2%, and e4 with 467 games and White scoring 50.7%. A practical takeaway: White often chooses simple development or central play, so you should stay alert for direct piece activity and not waste tempi.
Moves you should respect
Two moves are flagged as problems in this position. Bf4 is an inaccuracy and loses about 0.8 pawns; better was exd6. f4 is a mistake and loses about 1.3 pawns; better was exd6. For your training, that means you should recognise when White’s move is too ambitious and know that active central play is the test. If White sidesteps the best continuation, you still want to stay grounded in development, central control, and king safety.
