Indeed that is exactly what we are telling you ! Actually even bigger blunder is, that after Ne5 is played on the board ID125 doesn't see that fxe5 is winning and doesn't want to play it even after > 500k playouts.Daniel Shawul wrote:
Here LC0 moved Ne5 on TCEC's 43-core hardware! Note that this blunder is probably not due to a bug as most other engines would have it, but that the algorithm is working as intended and can produce such tactical blunders even on this massive hardware.
Are you telling me that this is not a problem for L0 or A0, and that it can be solved with bigger net and more training !?
The same position (with Ne5 on the board) but ID149 sees fxe5 as best (and with advantageous score) in just 8k playouts and as completely winning in about 20k
And that's the difference in just week of training, 4 days of which have been affected by serious under-promotion bug. So I guess if you wanted to show how shallow tactical blunders will never go away you should have picked a better example
Have you even looked at the board? You make it sound like LC0 had overlooked that Ne5 leaves the knight "en prise", while in reality it obviously overlooked the Re1+ move (so more like 4 plies tactics) and without Re1, Ne5 would be trapping the rook with f3, so it would be actually the best move in the position. If anything it's very interesting to see how human-like blunders of LC0 are, even a GM in serious blitz time pressure could blunder like that.Daniel Shawul wrote: That is a one ply tactic right there!
