Hi Richard,

Have you tried probing soft (not hard) in the <n> plies close to the leaves? This <n> needs to be calibrated for each engine, but you can find a condition in which the slow down is negligible. In that situation, the engine cannot be weaker.

Yes, I tried it. The slowdown was indeed almost negligible, but the search accuracy was badly degraded. After a soft probe cache miss the transposition table gets polluted with inaccurate scores. Critter's search then finds some unbelievable ways to avoid lines where tablebase probes were successful.
