I've been thinking about this idea for some time. Since blitz chess mistakes are inevitable due to time limitations (even at higher levels of play), it's a rather nasty version of chess for making great ideas. It becomes more instinct driven. For example, I'm rated 1800 in 24 hour chess on chess.com, but rated 1200-1300 there for blitz. Quite a disparity, and clearly shows my lack of experience to draw on. This means if I have time to calculate, coordinate, etc. that I play much better.
In blitz on this site, I'm rated roughly the same. However, often (way more often) I find myself getting a huge material advantage somewhere around +9/+10, but have had many games where I either run out of time or accidentally end up in a stalemate due to time. Given enough time, there's no way an opponent is returning from that. So I wonder why we wouldn't reward better decision making with a blitz mercy rule. Wouldn't this bring back better motivated decisions under the time limit, and reward better play without having too much time to think?
As the famous Bobby Fischer once said "Blitz chess kills your ideas". I think adding a mercy rule, would make it so you have time for at least a few excellent ideas. Thoughts?
