How much time does your favorite engine need to see that exf5 is not the best move?

Easy if you set to MultiPV=2.

You have too many cores. That's why simple test positions do not impress you.

Oops, just realized that while I was testing position with engines other performance sensitive tasks were running in background on my computer.

Hi Michael!
I for myself have one core only and sometimes that seems even too much for me.
:)
Thanks for the nice position. As a matter of fact positions is all chess is for for me, variants are the answers, but positions are the questions we have to answer or to be quite quiet, with or without engines.

Nothing like chess analysis on a 1/4-core processor!

Debugging is twice as hard as writing the code in the first

are, by definition, not smart enough to debug it.
