Here is a way to study exactly how spammers play their lines.

See their opening tree and decide how you want to attack them.

tailuge.github.io/chess-o-tron/public/openings/openingtree.html?player=rhex&filter=&pages=500&colour=white&trim=true

Nice, could you explain how to exploit its features at its max? :)

Pick the player whose games you want to study
Pick the variant you want to see
Choose whether you want to see their White or Black games
Pick as many games as you want to see (1000 or 2000 will probably give you plenty)
Green nodes at the end of tree are games they won
Red nodes are losses
Grey is draws
Click on an end node to see the actual lichess game
You can also use "Move filter" on the tree to pick specific openings if you want look at specifically

Click "Fetch Data" to import the data.
Click "Recompute" every time you change how you want to see that data... white vs black pieces... time controls... move filter... etc
