LCZero update (2)

[Jhoravi]

I defeated LCZero ID132 in Hard mode! This is probably the last chance that I'm able beat this fast growing monster. Note that LC0 made two positional sacrifices that made my position so hard to defend until I'm almost mated at move 35 with ..Qf4 threatening a seemingly unstoppable 36..Qh2+ mate. Luckily I found a tactic.

what is your elo ?

[Jhoravi]

I'm around 2100 and that's far below from the estimate 2500+ of LCZero

[duncan]

I'm around 2100 and that's far below from the estimate 2500+ of LCZero

do you think the 2500 elo is over estimated?

[Laskos]

I'm around 2100 and that's far below from the estimate 2500+ of LCZero

do you think the 2500 elo is over estimated?

Hard mode is AFAIK 2000 playouts, so about 0.5 s/move on a very strong GPU. The game was probably unfair.

Nice game Jhoravi

I think LCZero lost because it did not appreciate 24.Rxf5!

The match wasn't 100% fair because:
You were pondering!8-)
And Zero can't ponder now.
Ok it's not Zeros fault that it can't think when the opponent has to play a move but the fault of the developers.
