It's been a while, but I felt like I should share this one. I've gotten addicted to bullet over the last 6-8 months and need to play slower games to focus on improving again. I tell myself I'm going to play blitz but find myself playing bullet again! Anyways, here was my solution to fix my self-imposed dilemma :D
.lpools > div:nth-of-type(1), .lpools > div:nth-of-type(2) {
display: none;
}
.lpools > div:nth-of-type(1), .lpools > div:nth-of-type(2) {
display: none;
}
