ChessWorld.net, founded in 2000, is an online chess site.There isn’t a fixed number of “chess tactics”. Instead, chess has a small set of core tactical motifs that combine in endless ways. Think of motifs as ingredients — the recipes are practically infinite.
There are effectively unlimited tactics, because every position is different. But most tactics fall into a handful of repeating families you can learn and recognise quickly.
These show up constantly in real games:
