Improved Computer Analysis

What's with this "play might have continued"? I don't understand what it means.

A little feature I'd like to see with the computer analysis is the ability to link it to other persons interested in it without having to re-make the game in a blog or forum. For example, my friend wants the analysis from the game so he can study it and such so I can just handily give them the link. This would be a good idea since we can't analyze other member's games except our own.

I got checkmated and it says I have resigned too early and should have played on, in other words.

I did not know there was a new engine.  Maybe I'll cross-check my recent analysis request to see if anything seems unusual.

The analysis was not very accurate for a 2000 strength computer. In my game vs. Rickj, the analysis revealed that the losing move was just a mistake but in fact it was a blunder allowing mate in 5.

Now do it for the tactics trainer.

I'm either being dense or pedantic, but I don't see how black can promote without using his king.  I see:  46. Kf3 d5 47. Kf4 d4 48. Kf3 and then black can't make any progress without moving his king.  I realize black has won, but I don't see how he can do so without using his king.

While it's true that Black's king must participate, he need not escort, only waiting moves to put White in zugswang.  Here's how:

I don't think there's any zugzwang here.  At move 49, white can instead play 49. Kf4.  White can simply keep moving his king between f3 and f4.  Then if black ever plays d3, black responds with Ke3, capturing the pawn on the next move.  And if black instead plays f4 before d3, then Kxf4.

So black really needs to use his king, and not just for tempo moves.

You're right, I didn't see that before; I was using idea from positions with pawns 2 files apart.  White can blockade but not capture the pawns.

I didn't say I was smart, just Dumb1.
