C'mon children, let's begin our classes.
All suits (spades, hearts, diamonds and clubs) in poker are equal and do not influence the value of the card combination. According to the basic poker rules, all poker hands contain five cards and the hand with the highest value wins.
The poker hand which is the sequence of five cards with the same suit. For example: Jack, 10, 9, 8 and 7. As the suits do not matter in most poker games the ties are broken by the highest card in the hand. Straight Flush from Ace to ten is called Royal Flush.
In no limit poker games there are no any betting limits which means that the player can bet or raise any amount even the whole amount of chips the player has (All-in option). As you understand there are no any restrictions on the highest betting limit.
A faint heart never filled a spade flush.
