Jeg skubber fordi:
1. Ingen lader til at have ramt floppet
2. Turn har næppe hjulpet nogen
3. Villians tvinges til at tage en beslutning der kan koste stacken (og 45 mins arbejde).
4. Jeg plejer at være weak i disse situationer og checke til river og folde til et bet (med mindre jeg rammer river).
5. Jeg var PF raiser
6. Jeg var i den grad på (semi) tilt.
EDIT: 7. Limperen skal straffes :)
