Ok thanks. Sorry guess I should be asking this in a newbie strategy forum but weight 1 and weight 0.5 mean what?
Weight is akin to probability.
Your starting range when a hand starts preflop after dealing the cards and posting blinds is all possible combos with weight 1, this goes like this:
Quote:
AsAh: 1
AsAd: 1
AsAc: 1
....
for all 1326 combos.
We often denote it as short:
This means that all AxAy combos have weight of 1.
Now, when you start playing the hand you sometimes have a strategy like bet 50%, check 50%. Assuming that's a strategy for AA, this becomes:
Once bet or check is made. Let's say you bet and your opponent raises. Your strategy is now (for example): re-raise: 20%, call 80%, fold 0%.
Accordingly:
After re-raising "weight" for AA becomes 0.5 * 0.2 = 0.1
After calling weight for AA becomes 0.5 * 0.8 = 0.4
After folding weight for AA becomes 0.5 * 0 = 0
This can also be calculated for the whole range instead of just one hand.
Weight is a number representing an answer to a question: "How often do I have this hand in my range a this point in hand in comparison to how often I had this hand when the hand started". Weight of 1 means that you always get to this part of the game-tree with a given hand and weight of 0 means you never get there.
