Straddle is a forced blind, which is double the big blind amount and is always put before the cards are dealt. It allows you to act last in that round where players wanting to enter must at least call your blind raise, giving you the option to raise your blind raise, re-raise a raiser, check, or fold.
Straddle works in the following conditions
Straddle will only be enabled if the straddle checkbox is checked before the hand.
Straddle will only have an impact on the game pre-flop. If the straddle checkbox is enabled, once the flop is revealed, the minimum call amount for the players will equal the straddle amount. Once the flop opens, the minimum bet amount should equal the big blind amount.
Straddle cannot be initiated on the dealer button. Hence, straddle can only be posted if 4 or more players are part of the hand.
Simply put, running it twice allows all-in players to see the remaining cards twice instead of once. The pot is then split into two, half for the first set of community cards, and the other half for the second. You can only run it twice at a cash table. It is never done in a tournament. (It’s also possible to run it three, four, five, or as many times as cards left in the deck, but online play is limited only to twice.)
The option to run it twice occurs when everyone in the hand is all in. For example, if there were three players in the hand and only one of them was all-in, running it twice would not be possible. Also, to run it twice, every player in the hand must agree to run it twice. If one person decides not to run it twice, the remaining community cards left to be dealt, will be dealt normally only once. It is much more common for a hand to be ran twice between two players heads up instead of a multi-pot with three or more, although it’s still possible.
When two or more players are all-in with community cards yet to be dealt and all of them agree to run it twice, the remaining community cards will be dealt twice. For example, when everyone in the hand is all-in preflop and every player has agreed to run it twice, the community cards will be dealt twice. The first flop, turn and river will be dealt normally for half of the pot and a second flop, turn and river will be dealt for the second half of the pot. Please note that only community cards are dealt twice and not hole cards.
If the all-ins occurred on the flop, only the turn and river would be dealt twice, not a new flop for the second board since the all-in occurred on the flop. The same concept applies to the river.
If players were all-in on the turn and agreed to run it twice, only the river would be dealt twice. The first river and then another, each river with the four other community cards for half the pot.
