If you see an am along with a bm, that means that no, really, the am move is not a solution.

The inspiration for this test is a mish-mash of things, but mostly these are positions where about half the engines I tried got the wrong answer after 30 seconds using 6 cores at 3.4 GHz.

Some are positions I have studied over time and found interesting.

All of them are positions which I did not have an ID for, so they are most likely not contained in other famous EPD test suites (but there are probably exceptions to that since I did not check carefully).

First correction (bm should be a4):
2bqkbnr/3r1ppp/p1npp3/1p6/4P3/1BN1BN2/PP2QPPP/R4RK1 w k - bm a4; id "TI.021";

pv = a4 b4 Nd5 Bb7 Bb6 Qa8 Nc7+ Rxc7 Bxc7 Qc8 Bb6 Nf6 Rac1 Nd7 a5 Nc5 Bd5 f6 Bxc6+ Qxc6 Nd4 Qxe4 Qxe4 Bxe4 Bxc5 dxc5 Nxe6 Kf7 Nxc5 Bxc5 Rxc5 Bd3 Rd1 Bb5 Rc7+ Kg6 g3 Re8 Rd4 Re1+ Kg2 b3 Rb4 Ra1 Rg4+ Kf5
ce = 306

What means ;cce 161; in some epd lines?  Followed sometimes with "normal" ce 101;  e.g.  ti 30  ; cce 161; ce 101;

The cce tag is my own invention.  The cce field is calculated centipawn evaluation, based on the actual wins, losses and draws for the position.
This field becomes more and more important as the number of games rises.  If the number of games is in the thousands, it is better than the ce field.
