Well, then it is definitely time to go for one. Personally, I like his entertaining way but I know that for some he is not what they consider a good instructor. Anyway, I like his style and actually, so does my son (I once told him about a funny instructor from the Saint Louis Chess Club and before I could say his name he said "Ben Finegold". So he actually knew him before I did).
The one below is a beginner´s course on classic endgames. Even for me the bishop+knight versus king as well as the rook versus bishop endings need a refresher every now and then. Soooo, why not with Ben?!
(Apart from that, I did a refresher on a position within the Symmetrical English - based on one game I so bitterly lost last Sunday.)
