While all of the ideas mentioned are viable on at least some level, there are problems holding them back, in my opinion.
The issue with switching colors after a draw and playing is that many players will be winded after a day of playing chess and will just want the draw so they can go home. Also, if both players agreed it was a draw, and then switched and found out one side was better (and consequently won), the 'loser' would feel pretty bad, and I think hate towards this method of tiebreak would develop quickly.
You idea could extend OTB tournament times considerably, though that isn't too big an issue. The real kicker with this is the very concept of armegeddon chess. Part of the appeal of chess is the game being - other than the small advantage white holds for moving first - completely fair. Giving black draw odds and/or giving white more time will never exactly quantify to balance out the advantage the other side is recieving.
I think a lot of these tiebreakers are fun though! They could be used in a non-serious chess playing environment.
We all know that chess has a high number of draws, some of those draws are fine, fighting draws, and some are very bad for the game, pre-arranged draws and lazy draws, but how to solve this "problem"?
Well, I've seen some sugestions that are really drastic and completely change the game, they usually aim to eliminate opening theory in the hopes of reducing draws. I don't agree with any of those, yes FRC may be fun to play and a good game in its own right, but if we have to completely change the game to avoid draws, then what's the point? We are not even playing chess anymore.
I've also seen some sugestions to reduce the number of endgame draws, like turning stalemate into a win or at least half a win, but even tho you might say that the stalemate rule doesn't make sense, it actually makes chess endgames a lot more beatiful that would otherwise be, also most players fail to see the drastic changes that this would cause to the middlegame and, consequently, to the opening.
Some sugested that players should receive extra money acordingly to the number of wins they had during the tournament, I think that this could be viable as long as most of the money is split depending on the standings.
One interesting idea is that after a draw players switch colors and play with the remainder time of their clocks until there is a winner, but games with increment could go forever, so there is some problems.
So, what's my ideia? Most of the top tournaments use some sort of tie-breaks if the players are tied, but I'm particularly interested in the tie-breaks used for matches. If after the classical games the players are tied they play rapid, then blitz and then armageddon. What if we apply this to regular tournaments? The idea is simple, the players play a classical game, if the game draws they immediately switch colors and play a rapid game, 15+10 for example, if the game is still drawn they switch colors once again and play a blitz game, 3+2, and if they draw yet again they switch colors and go for armageddon. That way someone will walk away with the point, we still could have fighting draws, there would be no pre-arranged draws and, the main point, would be so much fun to watch. One consideration to be made is that the white player would get black in the armageddon, this may be good or bad depending on how you see it.
I should note that players would need a lot of stamina, think about it, after playing for 8 hours, 7 hours classic game and a 1 hour rapid game, they still had to play blitz and possibly armageddon, that's tough. So, what you guys think about that?
