Chess Timer in HD mode. Settings.

A blitz timer should affect the gameplay, otherwise it won't be a blitz, but just a regular timer.

I completely agree; the question is about the right amount of influence – that's why this thread was created, to understand the optimal value by testing and sharing the results iteratively...

P.S. On Jebus, I usually play with 60+8+0; this is roughly equivalent to an 8-minute SOD timer. Ideally, there should be a third parameter as well, but what should it be?)
