==Kuningasratsuavaus==
 
{{Käännettävä}}
Blacks valuable centre pawn is threatened with capture. But there is a tasty White morsel with nowhere to run to sitting on e4. Defend your own pawn, or go after Whites?
 
* 2...Nc6 is the natural move, combining defence of the pawn with control of the d4 square and refusing to commit another pawn. The extent of this moves popularity is such that the typical player of 2. Nf3 as White is already thinking beyond it to their third move, safe in the knowledge that any variation by Black will play into their hands.
 
In fact Black has a few other options, though all have their downsides.
 
* 2...d6, Philidors Defence, is the other safe option to defend the pawn. It restricts the f8 bishop to the e7 square, and grants White an advantage in territory, but it builds a fortress that cannot be easily battered down.
 
* 2...f6, Damianos Defence, is a wasted move. After 3. Nxe5, the knight cannot be captured as 3...fxe5 4. Qh5+ g6 5. Qxe5+ is most embarrassing.
 
If Black decides to go after Whites pawn, he has:
 
* 2...Nf6, Petroffs Defence. Black refuses to be cramped, but his symmetrical tendencies are unlikely to lead to a very active position either, unless White feels compelled to try and win the game by breaking the symmetry...
 
* 2...f5!?, the Latvian Gambit. The Latvian Gambit is the most vocally disagreed-about opening in chess. Depending on who you read, Black has either lured White into a minefield of tricks and traps leading almost inevitably to a violent death, or given away a free pawn.
