Tilt signs
Signs: speeding up, rebuying angrily, opening trash, chatting heat, 'one more orbit' after a stop-loss. Name them before the session.
If you notice two signs, walk. Your future self with money prefers the walk.
Two tilt signs → walk. No debate when playing buddy money.
'Tilt signs' (bankroll and mental game, G0): Seat choice is often higher EV than a fancy river line.
