Zero boards

After five cards are drawn:

1) If there are no pairs on the board - then no four-of-a-kind or full house is possible.

2) If there is not three or more cards of same suite - then no flushes (royal flush, straight flush, flush) are possible.

3) If there is not three cards within five ranks - then no straights (straight flush, straight) are possible.

Three-of-a-kind is the highest possible hand with a zero board.
