This is not short, it is gigantic...
Prefer short castle or long castle?

Short castles are harder to pick up but they're also lighter..... six of one; half dozen of the other.

Playing the London for example, I may easily go 0-0 or 0-0-0 or not even castle at all.
Or as the Modern defense goes, I’ll typically castle 0-0 or not at all.
100% depends on what opening I’m using and what’s best for that specific position.
Having a preference is a good way to play a position poorly and cost the game.
Now, if you just play for fun and don’t really care about wins or losses then have at it with your preferred method.

I do like to play 0-0-0+
Of course, most people see it coming and prevent it. But I tend to castle long more often.

I usually castle at the same side as my opponent, unless my opponent has all his pieces firing at that side.

Cute way to say you play boring

Long castling usually is for attacking games and then pawn storm which is good fun,
But I'm a wimp and prefer short castle for a safe game
