Is not so much slow play in itself (although it does) but players who try to hustle you when they think they are winning, but who grind to a virtual halt when they are losing and slow up whole tournaments as a result.
Ok, both are within the rules, and if playing a lot of games and using the full allowance is your universal style, then I'm the one who is showing a fault in my character. But the gamesmanship bugs me. No names, no pack drill.
