100 tough perft(7) positions

Post by sje »

100 tough perft(7) positions, the highest counts selected from over 37 million unique(7) positions examined to date:

https://dl.dropboxusercontent.com/u/316 ... /ToughGuys

Each FEN record is followed by three numbers:
1) the unique(7) multiplier
2) the perft(7) count
3) the product of the multiplier and the count

Another way to say the same thing is that these are the positions with the greatest mobility.

Hence, I would expect them to all have a good score for the side to move upon analysis (definitely more than would be predicted by any wood count difference).
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

There is nothing very extraordinary with the perft 1 on these positions. The highest is 52, but for an opening type position they are high .

# 1 on your list:

White(1): r1b1kbnr/pppp1pp1/2n1p3/6q1/4Q3/4P3/PPPP1PPP/RNB1KBNR b KQkq
Black(1): perft 1
total moves=52 time=0.00
Black(1): perft 5
total moves=172,325,656 time=6.24

Wait until later:

from an actual ccrl game played-

Black(1): 1bb2rk1/2qrnppp/2n1p3/1Q6/4N3/1B2BN2/1P3PPP/R2R2K1 w - -
White(1): perft 1
total moves=71 time=0.00
White(1): perft 5
total moves=390,052,280 time=12.77
White(1):
