The run has produced draft 12 record number 9 of 20, about three months since the last draft 12 record.

[d]

The perft(12) for the above is 43,376,546,076,090,990. This number is surely the least of the perft(12) counts for the ply one positions.

The worker thread for 1 f3 has concluded and the thread for 1 g3 has started. The other threads are working on 1 c3, 1 c4, 1 d3, 1 d4, 1 e3, 1 e4, and 1 f4.

Back in December 2011, I posted the Perft(11) of 1.- f3, f6 calculated with JetChess 1.0.0.0:

Perft(11) of 1.- f3, f6.

Code: Select all

1,165,301,810,426,206 (move pathes after 11 half moves).

It is good to see that this huge number is correct (I guess that this draft 11 will be the smallest of all the 400). Thank you very much for running Perft(13).

It's always good to see verification of results. Even though the 1 f3 f6 result is likely the least of all perft(11) subtotals, a correct calculation implies that many, many sub-calculations are also correct.

For the Sicilian Defense (or "Defence"):
[d]
The perft(11) for the above is 12,238,301,482,896,473 and this is the largest perft(11) seen so far in the run.

Compare the above with the Caro-Kann:
