I had the opportunity to play a round of Fusion 8 (high/low) last evening. We used the following sequence:
Deal 2 cards down to each player
Betting round
Flop
Deal 1 card down to each player still in the hand
Betting round
Turn
Deal 1 card down to each player still in the hand
Betting round
River
Betting round
We were six-handed and played it fixed limit. IMO, most of the comments ITT were dead on. I scooped two big pots by playing big cards and making Broadway, which was the nuts both times.
I'll be making a card for Fusion and Fusion 8 and will include it in the next update.
