Generally speaking what is the minimum raise amount after a new card is dealt in No-Limit Texas Hold 'em?
Pre-Flop. Small Blind $1, Big Blind $2. Everybody calls.
Post-flop. Is the minimum raise still the big blind, $2?
What is minimum? Let's say during post-flop round someone then raises $10 and everybody calls.
After the turn, is the minimum raise now $10 or does it go back to the big blind of $2 since it's a new round?
After the turn someone raises $10 and then another raises $10 for total of $20.
What is the minimum after the river now? Is it $20 as in continuation of minimums from previous rounds of betting or something else?
I hope I'm being clear.
I read over the suggested possible duplicate "Trying to express NL betting rules formally, did I miss anything?" and didn't see this specific question answered there. That question does say that the minimum goes back to zero on the post flop but then mentions the minimum is max of current bet plus raise or big blind. It doesn't address subsequent rounds or specifically if prior round best affect the minimums for subsequent rounds of betting.
I realize there can be different rules and different situations and dealers and such; I'm just looking for general guideline. I'm writing a programming tutorial for internal use and using NLHE as the programming exercise so it actually isn't important if I get the rules exactly right. I'm not clear on this issue though after reading a lot rules from a lot of sources.
