Re: Test Position: One-way street
dont know how hiarcs reads this kinds of positions, but time & again it sniffs this stuff out remarkably fast.

Re: Test Position: One-way street
looking at it in mpv, hiarcs never 'drops' bxe7, just scores it a couple centipawns below Nxe5 until a certain depth (& then again, much lower, at a later one). so nothing too clever.

Re: Test Position: One-way street
as i said, you get a better idea of what your engine really understands if you put switch mpv on. eg i'm running zappa right now and it's been Nxe5 all the way, but guess what - second variation is Bxe7 & it's 1 centipawn away from being a tossup (.94 to .93).

1.Nxe5!
I analyzed this position on my little Asus Netbook. Using Arena, I gave 3 engines 5 minutes to find the right move. Ivanhoe 999963 and Fire 1.3 found the right move, but Robbolito 0.09 fell in the e7 trap. (Don't mind the weird piece letters, it's French
)- Ivanhoe 99963:
