Here I ask Leela 236 GPU to solve the same puzzle and it took her only 10 seconds on GPU versus 50 seconds on CPU. Mean we'll have a much stronger Leela on GPU than CPU obviously (tournament results later if anyone wants, not over yet) as I guess it's not the new ID from this afternoon that has really changed the problem. I'm surprised the difference being that huge with Leela finding 5 times faster on GPU. (It's really no monster, just a good old GeForce GTX 660M)

At move 20. we can see how Leela -like Alfa before her- has no fear to use her king in the battle. But now look at move 33, maybe you can stop reading at move 33 (or 32 for harder difficulty) black to play and if you haven't found the danger in the puzzle, try to see if as black you would find the way to catch Leela in a dirty trap.
Lila ID : 238 (from THIS morning).
The match happened at home with Leela on a CPU (not at her best here for sure) at a very fast rate Ultra Short Blitz (Blitz 10 seconds + 1.2 seconds/move).
Opening "Nimzowitsch Defence"
Variation "2.d4 d5 3.exd5 Qxd5 4.Nf3"
Site/ Country: Cylvouplay, France Level: Blitz 0:10/1,2
Hardware: Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz with 7,9 GB Memory
Operating system: Windows 7 Home Premium Home Edition Service Pack 1 (Build 7601) 64 bit
As you can see below it took 50 seconds for Leela to realise what was going on when I gave her the puzzle in analyse mode (so it's not a bug, just a difficult/long task for her).
Let me know if you want more games with Leela or other engines (I use to save the most interesting games from tournaments on Arena @ home). If you like it I may post more. It it's a yes, please let me know if you want only Leela or any engines, and if there's any use to make a puzzle out of the interesting moments of the games or you prefer just the moves.
