Needles in a haystack

How many famous chessplayer surnames can be found in the 20x20 grid below? The names are hidden in rows, columns and diagonals. To make it easier, no names shorter than six letters were used, and all surnames are read from left to right (diagonals and rows) or from top to bottom (columns).

Dear Chess-Playa ; thanks !  And I found 31 names ...

This is very, very close, but can you find more?

Before counting again, I think it should be 8+8+8+8=32, a cryptic answer, but I dont want to give more info...

I am going to check again !!!

I think I found it : 9+8+8+7=32 total !     Regards, Ger.

Yes, this is the correct number, RomyGer. Very impressive that you got it so quickly.

Thanks ! And, through the years I have made more chess puzzles for our club magazine, in Dutch of course, moreover, when I see a puzzle, I have to solve it, kind of an addiction...  I will try to find such an old one, to publish here, or just try to make another one,  give me some time..   Regards, Ger.

By the way, I saw your puzzle 59 minutes after placing here, and am still the only one, how is this possible, chess players love to solve puzzles, be it on the board or others !

lol. I gave up. I blame fading eyesight. Thats my story, and I'm sticking to it.
