Where we desagree more is on example 2 where the raise should be 3500 or 4000
Because if UTG goes all in but can't match the big bling what is the minimum rise for the player in middle position

Sebastien:
Your original post doesn't say whether this is Limit or No-Limit.
For LIMIT, from Robert's Rules of Poker, ver. 10, Chap 2, Sec. 3.5: Betting and Raising, Sub. 7. In limit play, an all-in wage of less than half a bet does not reopen the getting for any player who has already acted and is in the pot for all previous bets. A player who has not yet acted (or had the betting reopened to him by another player's action), facing an all-in wage of less than half a bet, may fold, call or complete the wager.
An all-in wager of half a bet or more is treated as a full bet, and a player may fold, call or make a full raise. (emphasis added) (An example of a full raise on a $20 betting round is raising a $15 all-in bet to $35.
Since in your example #2 the $1500 wager is more than half a bet (the amount of the big blind) it would be treated as a full bet. Per the example, the raise by the following player would have to be to a total of $3500.
For No-Limit, from Robert's Rules of Poker, Ver. 10, Chap 2, Sec. 14.1: No-Limit Rules, Sub. 2: "The minimum bet size is the amount of the minimum bring-in, unless the player is going all-in. The minimum bring-in is the size of the big blind unless the structure of the game is preset by the house to some other amount (such as double the big blind). The minimum bet remains the same amount non all betting rounds. If the big blind does not have sufficient chips to post the required amount, a player who enters the pot on the initial betting round is still required to enter for at least the minimum bet (unless going all-in for a lesser sum) and the preflop raise must at least double the size of the big blind.
At all other times, when someone goes all-in for less than the minimum bet, a player has the option of just calling the all-in amount. If a player goes all-in for an amount that is less than the minimum bet, a player who wishes to raise must raise at least the amount of the minimum bet. For example, if the minimum bet is $100, and a player goes all-in on the flop for $20, a player may fold, call $20, or raise to at least a total of $120(emphasis added)."
In no-limit the half a bet rule does not apply so the
minimum raise would be to a total of $3500.
I suggest you look for Robert's Rules of Poker (ver. 11 is now available on-line) at "
