What to do here

The sequence 1. 2. 3. aims at a specific setup: your f3 pawn watches e4 and g4, your e3 pawn watches d4 and f4, and your king stays on f2 uncastled.

1. defends e4 and g4 with a pawn. It has a visible cost: the g1 knight loses the f3 square and the e1-h4 diagonal opens. If you play 2. after with it open, is mate, and it happened in 139 public games. With 2. you give up castling, and the king still sits on that diagonal: after the e7 pawn still blocks d8-h4, but moves it and the black queen sees h4, from where it would check on f2.

Instead of 2. there is 2.: it takes the center with a pawn without moving the king and opens the c1 bishop's diagonal, but the king stays on e1 on the open diagonal. If you choose 2. and follows, you have two continuations. 3. puts a pawn between h4 and f2 and stops that check. 3. opens the f1 bishop's diagonal, watches d4 and f4, and blocks the c5-f2 diagonal before arrives; if the black bishop gets to c5, it pins that pawn against your king. develops and eyes e4 and g4, the squares your f3 pawn watches.

At 900 to 1700 almost nobody gets this far: the position after 3. shows up in 228 of 23,729 games. Expect your opponent to answer (4 in 10) or (1 in 4) and you to choose among 2., 2. and 2.. If you reach the e3 and f3 setup, your king stays uncastled on f2 and your job is to keep control of e4. Order matters: first you decide how to treat the h4 diagonal, then you develop knight and bishop, and you leave f3 alone, since it holds e4 and g4. Other third moves are less common: 3. in 91 of 491 games, scoring worse than 3., and 3. in 48. After , strong players split the third move between 3. (75 of 144) and 3. (55).
