Fischer Increment, Explained
The Fischer increment adds a fixed bonus (e.g. 3 seconds) to your clock after every move you complete. It rewards fast play and prevents pure flag-fests in the endgame, which is why it is the default for online blitz and modern classical chess.
Bronstein delay gives back only the time you actually spent, capped at the increment — net-equivalent to simple US delay, which counts down a waiting period each move before your main clock starts. ChessTimer supports all three so you can match any event's rules exactly.
Fischer vs Bronstein — which should I use?
They are net-equivalent in time, but Fischer can grow your clock while Bronstein cannot. Use whichever the event specifies; for casual play Fischer is the most common.
