Plan fourth for fifth

'Plan fourth for fifth' (stud hi-lo, G3): Scoop and freeroll beat split-hope. Update both halves every upcard.

Later streets: bricks that kill your low (or their low) change the scoop math immediately. Update both halves every upcard.

If you wouldn't call fifth, don't call fourth 'for one more' unless the price is tiny and fifth likely checks — don't assume that.
