OpenPPL In Practice

If you have read this manual up to this point you have some basic understanding of OpenPPL: syntactical rules, symbols, etc. But the main thing — turning your poker-knowledge into bot-logic — may look like a different kind of beast, if you have no programming experience at all. So let us take some small examples and see how OpenPPL is used in practice.

Folding Trash

           ##list_of_biggest_trash##
                       // Trashy hands.
                      // Never to be played, except we are in the blinds
                      K8s K7s K6s K5s K4s K3s K2s Q7s…
                      K8o … 32o
​
           ##f$preflop##
                     // Make life easy and get rid of the greatest trash
                     WHEN NOT In BigBlind AND list_of_biggest_trash Fold FORCE

Open-Raising On The Button

WHEN StillToAct = 2 AND Calls = 0 AND Raises = 0
WHEN hand$AA OR Hand$KK OR … RaiseTo 3 FORCE

Threebetting A Steal-Raiser

        // LastRaiserPosition <= 3 means: CO, BU or SB
        WHEN Calls = 0 AND Raises = 1 AND LastRaiserPosition <= 3
              WHEN AmountToCall <= 3 AND list... RaiseTo 9 FORCE

Contibetting

         ##f$flop##
             WHEN Bets = 0 AND BotIsLastRaiser
                         WHEN Opponents = 1 AND Random < 80 BetHalfPot FORCE
                         WHEN Opponents = 2 AND Position = Last RaiseBy 66% FORCE

Effective StackSize

        ##f$EffectiveStacksize##
              // First orbit preflop only, as it uses MaxStillToActStackSize
              WHEN StackSize > MaxStillToActStackSize RETURN MaxStillToActStackSize FORCE
              WHEN Others RETURN StackSize FORCE

Push/Folding In A SNG

        // Going into push-fold-mode when stacksizes are small
        // But be careful!
        // We don’t want to push loosely if something is wrong with the stacksize,
       // e.g. because the table was occluded, so we check, if it is non-zero.
       WHEN EffectiveStacksize > 0 AND EffectiveStacksize <= 13
       WHEN Calls = 0 AND Raises = 0 AND (Hand$… RaiseMax FORCE

Detecting A Limp-Raise

        // First action preflop
                WHEN BotsActionsOnThisRound = 0 AND Calls >= 1 AND Raises = 0
               // FirstCallerPosition is limited to first orbit preflop only,
                // so we remember it, making use of advanced memory symbols
               WHEN Others me_st_MemFirstCallerPosition_FirstCallerPosition
               // Then continue with normal bot-logic
              ….
​
      // After that we can detect a limp-raise like that
      // (assuming, there are no other raisers in the pot)
      WHEN LastRaiserPosition = me_re_MemFirstCallerPosition …

Counting Outs

      ##f$MySimpleOutsCounter##
          WHEN (HaveNutFlushDraw AND HaveNutStraightDraw)
                     // We already have 9 + 8 – 2 duplicates
                    // Plus up to 6 undiscounted outs for Overcards
                    // but some may be already counted for the flush
                    // (if we want to make it extra good, we should check the colours
                   // of our hole cards with OpenHoldems symbols $$ps0 and $$ps1)
                   // The others should be discounted a bit
                   WHEN (Overcards = 2) RETURN 18 FORCE
                   WHEN (Overcards = 1) RETURN 16.5 FORCE
                   WHEN (Overcards = 0) RETURN 15 FORCE
           WHEN (HaveNutFlushDraw) // AND NOT HaveNutStraightDraw
                  WHEN (HaveInsideStraightDraw AND Overcards = 2)…
…

Calling According To Odds And Outs

          ##f$CardsLeft##
                   WHEN betround = 2 RETURN 47 FORCE
                   WHEN betround = 3 RETURN 46 FORCE
                    // Drawing at other betrounds doesn’t make much sense
                   WHEN Others RETURN -1 FORCE
​
       WHEN AmountToCall / (AmountToCall + PotSize) > f$Outs / f$CardsLeft Call FORCE

Playing Fit-Or-Fold Multiway

       ##f$HaveStrongDraw##
              WHEN HaveStraightDraw OR HaveFlushDraw RETURN True FORCE
              WHEN HaveInsideStraightDraw AND Overcards = 2 RETURN True FORCE
​
       ##f$HaveTopPairOrBetter##
              WHEN HaveTopPair RETURN True FORCE
              WHEN HaveOverPair RETURN True FORCE
              WHEN HaveBestOverpairOrBetter RETURN True FORCE
​
      ##f$flop##
             WHEN Opponents >= 3 AND NOT (f$HaveTopPairOrBetter OR f$HaveStrongDraw)
             WHEN AmountToCall = 0 Check FORCE

Closing The Tables

      ##f$Close##
      WHEN issittingout
           AND elapsedauto > 300 // 5 minutes without action
           AND nopponentsseated < 4
     RETURN True FORCE

Poker Tracker

      ##f$flop##
      WHEN BotRaisedBeforeFlop and HaveNothing and Opponents = 1 and Raises = 0 and Bets = 0
      WHEN Position = Last and pt_flop_checkraise_headsup 0.7 and pt_hands_headsup >80 RaiseTwoThirdPot FORCE

Now it’s up to you. Let the fun begin!
