About the 5 d2 time control
Where Fischer increment adds two seconds to your clock after each move, simple delay holds the clock for two seconds before it starts counting — shielding your base time without ever adding to it. Quick moves cost nothing; only time beyond the buffer runs off your five minutes.
In practice the endgame feels noticeably fairer than 5+0: king moves, queen checks and simple retreats no longer eat into your main time. It is the standard blitz delay control in USCF-run events, and a direct substitute for 5+0 if you prefer the delay mechanic over Fischer increment.
In short: 5 minutes per player with 2 second delay, in the blitz range. Tap below to start it now, or read more about how the time-control tiers compare.
