LucaP,
My answer is yes to what you have calculated. I added a little twist with the raise amounts. For some reason, in PL we rarely mention these amounts.
This is the formula that I introduced 3 years ago:
I want to add the following FORMULA that should be used to determine the maximum allowable bet for pot-limit. Any player facing a bet, may raise 3 times the largest bet required for a call, plus the remaining trail, plus the pot. Example: Pot size 100, Player A bets 50, Player B goes all-in for 20, Player C wants to raise “pot.”
Answer: Three times 50+20+100=270.
Formula works for any player when it is their turn to act, even the under the gun position pre-flop. Example: Blinds $5 and $10. UTG bets “pot.” Three times the Big Blind plus the Small Blind. Three times $10+$5=$35. PLEASE NOTE: The small blind is sometimes counted as a completed bet to the Big Blind, this will allow the “pot bet” to increase to $40.
SB $1 BB $2 UTG straddles to $4 amount. To calculate a pot size raise by the SB: three times $4 = $12 + 1+$2 =$15 ($11 raise)
BB calls $13 more at this point…SB has $15…BB has $15…UTG has $4 facing a $15 bet. If we follow the formula: three times $15 = $45 + $15 +$4…The $15 and the $4 are the “string” of bets remaining.
So the total amount (pot size bet) to the UTG straddler would be $64…A $49 raise!
