How far can you calculate in Chess? How about 125 moves?


White to play

Blathy,O - 1938 1-0

Mate in #125

Yes, 125 moves! I'm not joking. 

After digging through musty books and journals, I found this interesting chess puzzle which was composed by Blathy,Otto in the year 1938. White forces a checkmate in 125 forcing moves! This is the longest combination I have ever seen. How about you?

I will post the answer to this puzzle in tomorrow's post. Stay tuned...

The game may be drawn if each player has made at least the last 50 moves without the movement of any pawn and without any capture Fide rules

lol, that's a nice way to refute the composition :P :) We will just assume that this isn't a tournament game; just a composition.
