Im sure this has been proposed somewhere...but..

What if you can show a forced mate through conditional moves... and claim the win.

Forced checkmate is understood to mean... no matter what line of play your opponent tries... the result will be... checkmate as proven by your conditional moves.

What I'm talking about where this would be really handy... would be the last game left in group play of a very large tourny (e.g. annual chess.com tourny) where most or all of the other groups have finished (to go to the next round)... and everyone is waiting for that one game.

I saw one game come down to a typical K+Q vs. K and it took months to finish.......from there.

What do you guys think?... a button that is avaiable to claim a win... only if proven through conditional moves?

Nah.  If you've got a forced mate, just play it.  Or take the win on time if your opponent is a jerk about it.

Seems a good idea, would not be difficult to program.

Play it out. The beauty of chess is in the moves,even a forced mate.

You know what?... my fault. I was not clear enough... or better, I was not clear at all....

WHY... you would want to force mate.

If an opponent is NOT resigning in a LOST position and has been taking.... forever... to move.

THEN.... you just plug in your conditional forced mate moves... and you claim the win.

Now.. what do you think?

... yes, a button would be helpful to non-premium players

... but, a non-premium player is only allowed one (1) conditional line of moves ... so, he is not able to show all the lines of the forced mate in cases there are more than one (1) conditional line of moves ... unless the button would allow him to enter all the conditional lines.

In the 19th Century, in OTB tournaments and matches, and even in individual casual games, it was quite common to announce forced mates.  Many published games from the era ended with, "and White announced mate in 4" etc.

So what the OP is asking is an option to use that method of ending the game, which has a certain retro-cool appeal to it.  But by the time you went through entering the details (assuming it were available to non-premium customers in the case of forced mate), you could probably just mate the guy.

I really don't see the problem here.  I've played hundreds of OTB and correspondence rated games, and never once did I consider announcing forced mate.  When it came to that, the opponent usually resigned once he saw it, or else I mated him.  I felt no sense of loss of honor.

I once played a game with 14-day time controls (never again!) on the Facebook application, which didn't have conditional moves before the big merge. The opponent was obviously going to play on until checkmate and was taking an average of seven days per move towards the end. The game lasted about four months.

When I saw a forced mate in three (with KQ+P vs. K+P), I announced it, and the guy asked, "Really?" and actually played his last couple of moves much faster.

So there are exceptions.

 Lol... yes, there are worse problems and thanks for your always insightful NM opinion. What I'm talking about where this would be really handy... would be the last game left in group play of a very large tourny (e.g. annual chess.com tourny) where most or all of the other groups have finished (to go to the next round)... and everyone is waiting for that one game.

I saw one game come down to a typical K+Q vs. K and it took months to finish.......from there. 

Mating is how  life goes on...no need to force it...

I wouldn't play a game under those conditions: just because my opponent can see he's won, it doesn't mean that I necessarily can.  And if I'm not allowed to see and get a feel for HOW my position leads to checkmate, I'll never learn.

 please do not copy me, this one was MINE lol jk some1 did it b4 me but i have more posts. HA! here---> throw an octupus today!

well yeah, but a lot of those were quoting the princess bride when we thought you were being funny. 

planeden, i am always serious about being funny.

many people just don't seem to understand how hard it is to be funny.  i study that a lot more than i study chess.  which may be why my chess rating is so low.  not sure what my funny rating is, but that is pretty subjective anyway. 

And who is to verify your force mate sequence? I can already imagine chess.com hiring new staff just to confirm the claimed wins. And what if you miss, and your nice 6 move mate sequence has a hole in it. And to tell you that you're wrong, would actually help you by giving the advice about the game in progress. So, my answer is, read the laws of chess, basic objective is to checkmate your opponent, so just do it.

I believe this might be a joke, at least I hope it is.

Just do conditional moves or play it, because maybe you missed a move or thought that it wasn't a forced mate when it really was (allowing an unfairly won game).
