Week 102: the Modern Defense for beginners, seen through three quick losses
Eleven games from January 5 to 10, 2026: 4 wins, 7 losses, rating 1296 → 1283 (−13). Most of the story is in my Black games, where I play a g6 setup against almost everything. So this entry is a practical look at the Modern Defense for beginners, from the point of view of someone who keeps choosing it: two smooth wins, and three losses that were over before move 18.

As Black I went 3–3; as White only 1–4. The blunders were spread out: eight in the opening, nine in the middlegame, three in the endgame. My wins averaged 83.0 % accuracy and my losses 68.5 %.
The Modern Defense, game by game
The Modern is simple to describe: Black plays g6 and Bg7, puts the bishop on the long diagonal and lets White take the centre with pawns, planning to attack it later. The Pirc is the close cousin with an early Nf6. Both are flexible, and both give White time. That time is what I kept misusing.
Game 1948: the queen comes out too early
Against jovanagogo (1326) White played 2.Bc4 and 4.e5, and after 4...dxe5 5.Nxe5 e6 6.O-O I put my queen in the centre with 6...Qd4, attacking things. On move 7 I added a bishop.
Both moves attack the knight on e5. The difference is what White gets next. After 7...Bd6 the engine's answer is 8.c3, a pawn move that attacks my queen on d4, which has no defender (+2.84). White gains time, and my queen has to run while my king is still on e8. With 7...Nc6 the game stays only slightly better for White (+1.04). In the game 8.c3 Qc5 9.d4 Qa5 followed — two more queen moves — and on move 14 White sacrificed on f7 and e6 and mated me with the queen (game).
Game 1947: the pawn push that gives White a target
The day's first game was the good version. Against Badi2x (1327) White answered 1...g6 with 2.e5, and on move 11 I was slightly better.
11...Nf5 attacks the bishop on g3 and keeps my edge (−1.34). 11...f5 hands White a possibility I wouldn't have noticed: 12.exf6, capturing en passant (a pawn can take a pawn that just moved two squares past it), which attacks my knight and my bishop at once (+1.32). My opponent played 12.h3, the game went on for 44 moves and I won by checkmate (game).
Game 1949: the other side of the board
With White against user200king (1334) my problem was the classic one. My queen went to g4 to attack the knight on d7 — and left my own knight on d6 hanging.
The engine's first line after 22.Qg4 is 22...Qxd6, the queen takes my knight (−7.96, "black is completely winning"). Moving the knight away first, 22.Ndf5, kept me only slightly worse (−1.37). That's what happened (game).
The two other quick losses
Against maddydaddy1235 (1312) in a Pirc, my knight had taken White's rook on h1 and I was completely winning (−7.38) on move 16. I played 16...Ng3, and 17.Qxh8 was mate: my king had never castled and White's queen on c3 had a clear diagonal to h8. Castling, 16...O-O, kept the win (−7.35). And against GoldiSingh143 (1285) White played 4.Ng5 against my g6 setup and the game lasted 12 moves. Two of my three quick losses came from positions where I had been clearly better before one move threw it away.
The lesson of the week
The Modern Defense for beginners is not about memorising lines. It's about two rules that my losses broke: don't bring the queen out early while White can attack her with pawns, and get the king out of the centre before going material-hunting. In game 1955 my king never left e8; in game 1948 I did castle, but my queen's early trip had cost so many moves that White's attack arrived first.

Frequently asked questions
Is the Modern Defense good for beginners?
It can be, but it lets White build a big centre and attack early. In week 102 my g6 setups as Black scored 2 wins and 3 losses, and all three losses were over by move 17.
What is the most common mistake in the Modern Defense?
In my games it was bringing the queen out too early or leaving the king in the middle. In game 1948 my queen went to d4 on move 6 and I was mated on move 14.
Should Black castle early in the Modern Defense?
In game 1955 castling on move 16 kept me completely winning (−7.35); my knight move 16...Ng3 instead allowed 17.Qxh8 mate.
