re: Poker & Is this a normal trend or is something special happening?
It's not just summer. Liquidity of poker networks have been coming down for years, and it is faster than ever. Many networks struggle to maintain enough players and some networks have lost 50+% of their player base during last two years. One matter is that ring-fenced countries that have their own player pool and others which has forbidden online poker remove players from global market.
In matters of Stars, there's also the fact that casino and sportsbook eat liquidity from poker.
