user8134: Are there any chess engines out there that will allow me to add arbitrary amounts of time to their clocks as the game progresses? I am interested in experimenting with two engines playing each other with me manually (or programatically) giving each bonus time throughout the game according to an algorithm I've developed.

user20467: I don't know for sure on this, but if you go on Lichess, there is an option to add 15 seconds to your opponent's clock in live chess, I do not know with computer chess. I usually use Chess.com's live chess VS a bot.
