Tablebases and deep search are amazing. I mean, white has the right colored bishop, two pieces and two pawns just like black. Sure, I would trade the bishop for a rook, but still it does not look hopeless to me. I would definitely play on OTB in an actual game.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Looks can be deceiving. It's a mate in 36 the last time I checked.

I never did a serious analysis of the game with engines but
I wonder what is the hard move to find for chess engines that caused some people after some analysis to say that maybe the position after 3...f4 is a draw.

Well, that kind of spoils the fun, doesn't it?

I have no intention of putting any effort into finding a faster mate than what I'm seeing, so if we follow my line I'll be delivering mate in December 2021.

Nevermind.

Figures I can beat you in 11 days if I send my move plus 11 conditionals. If you accept them then I'm checkmating you July 15. If you deviate then I'll mate you in fewer moves (you know other white moves get mated faster than this).

My move:

31...Rd4+ -M115

Conditionals:

IF 32. Ka5 THEN Rxf4 -M114
IF 33. Bh3 THEN Ra2+ -M113
IF 34. Kb6 THEN f5 -M112
IF 35. Kc5 THEN Rc2+ -M111
IF 36. Kd5 THEN Kf6 -M110
IF 37. b6 THEN Rcc4 -M109
IF 38. Rd1 THEN Rc3 -M108
IF 39. Bf1 THEN Rb4 -M107
IF 40. Ra1 THEN h3 -M106
IF 41. Ra6 THEN h2 -M105
IF 42. Bg2 THEN Rc1 -M104

Almost anything would be faster than the DTMs you listed. :mrgreen:

So now, all of a sudden, you want to try to optimize your play?? :mrgreen: :mrgreen: :mrgreen:

And you think the best way to do that is to use conditionals?
