Also @GallifreyanKing, note that I could not block the check with N3f4 or N5f4 since the witch would make my knight transparent, so I would still be in check.
Bulldog with witch Challenge game (Martin0 - vickalan)

Good work on the worksheet with elo scores. Within a day or two I'll check for finished games and update the Top Players thread also with any results. Btw, I think the chart is the most interesting sheet - you should make that first visible sheet (although I know it's easy to switch between pages).

@GallifreyanKing, I sent a note to @friedmelon, but he hasn't replied (and also has not played a move for about 1 day in a game).
I'll also leave a request (here) to see if anyone else would like to play. Also, Togepi has not moved in a few days in another game, so that game might be done (I get a win if he is a no-show). If that game is complete, then I can play you if you'd like. Martin0 is calculating elo scores, and your score increases a lot more if you win over a better player.

I could play if it's okay.
One question: how did the rook jump over the pawn in one of the first moves?

FortunaMajor, the rook was able to jump over the pawn because the pawn was made transparent by the witch.
That's awesome that you'll play GallifreyanKing. I'll start a thread for the game soon and update the board about once per day. For all new players - make sure to understand the witch completely before starting any games. You can see a diagram of the witch's moves (here - post #43).

I didn't see that this had started ... a new World Championship! Good luck to you both (vickalan in particular seems to need it atm).

Thanks JohnHS.
Sorry for the delay. I've been traveling during the Thanksgiving holiday. I still won't be home for a few days, but I hope I don't need a long delay again.

I am home now after seeing family in different places - I slept in my car on the way home for a few hours, but I think I should be back on my normal schedule - at least till Christmas.

Yay, another new player
Also, @vickalan, it was good you mentioned friedmelons score was 2 wins/1 loss. I looked at my spreadsheet and apparently I had marked the result wrong for the game between friedmelon and foofooes where friedmelon won. Now it is updated and friedmelon does indeed have 2 wins/1 loss.
