A Game I Just Played against Computer Level 6

I think the computer played below the stated level.

?

Hmmm. A computer allowing a mate in one!? Strange indeed!

Yeah.? 21....Qd6 would have been much better (and what I expected).

Cool. I have seen Jerry (ChessNetwork) play SF6, it blows hot and cold. So Bxh2+ is an expectation of breaking the pin by moving the queen, expecting BxN gxB ... Rg8 to mate you.
Should it have seen 21. ... Qd6, dunno. Clearly you would simply re-position the queen and run your g-pawn. The engine also went wrong with 7. ... e6 as getting the q-bishop out is a major theme of the Caro-Kann.
Well deserved win.

I'd ask for my money back.?

the? Bishop? sacrifice? is? dubious? it doesnt deals with the mate treat . g6 would have. Not taking back with Q on move 14 also strange

Thanks. The computer is indeed a strange opponent.?

Good game, but level 6 is not too strong. Try level 10

I have.

It's still a pretty finish. Well done!

Am I just seeing things or has "?"  been added to comments. 

The question mark is added to the actual move itself. You right click on a move, and at the bottom, you will see a whole bunch of notation symbols, including the I am stupid

You are not seeing things. I just called the thread up
I wrote "Well deserved win"
I saw "Well deserved win?"
So I edited my post back to what it said to start with.

Thanks..  must be a bug... a questionable one though.

Earlier today, I noticed that the site had all sorts of additional script. I think there was a bug. I hope it's now fixed.

1. It is only level six.                                                                                                             2. After 21....Qd6 Nxc6+! so 21....Qc7&you are still winning, even 22.Nxc6+ bc  23.Qxc7+ Rxc7 is easily winning for you.                                                                             3.How much do level 6 computers blunder?

I play the computer on level 5, and even though I rarely win, I can win most easily by an early, hyper-aggressive attack along one of the files along the edge.  Perhaps the design of its program causes it to lack peripheral vision, since in cases of a peripheral attack it seems to play worse than usual.

I don't like playing computers since at some point they really blunder a piece or even a checkmate.
Why, we humans might do it as well, but not as bluntly as a computer doing it purposely.

Drills are interesting, though. Computer's always at max level so you really must be accurate.

(nice game btw)
