Are my hidden cards a pair

This simple bot checks if your hidden cards are a pair (i.e. if they have the same rank). If it is a pair, the bot goes all in, otherwise it folds.

import { createBot, getNameFromCommandLine, isSameRank } from '@cygni/poker-client-api';

const bot = createBot({ name: getNameFromCommandLine() });

bot.registerActionHandler(({ raiseAction, callAction, checkAction, foldAction, allInAction }) => {
    const gameState = bot.getGameState();
    const myCards = gameState.getMyCards();

    if (isSameRank(myCards[0], myCards[1])) {
        return allInAction;
    }

    return foldAction;
});

bot.connect();

Are my hidden cards suited?

A bot that checks if your hidden cards are suited, and if your cards are suited in diamonds. If that is the case, go all in - otherwise fold.

import { createBot, getNameFromCommandLine, isSameSuit, suits } from '@cygni/poker-client-api';

const bot = createBot({ name: getNameFromCommandLine() });

bot.registerActionHandler(({ raiseAction, callAction, checkAction, foldAction, allInAction }) => {
    const gameState = bot.getGameState();
    const myCards = gameState.getMyCards();

    if (isSameSuit(myCards[0], myCards[1])) {
        if (myCards[0].suit === suits.diamonds) {
            return allInAction;
        }
    }

    return foldAction;
});

bot.connect();

Are my two hidden cards jacks or higher?

A bot that checks if your hidden cards are jacks or higher. If so, go all in - otherwise fold.

import { createBot, getNameFromCommandLine, ranks } from '@cygni/poker-client-api';

const bot = createBot({ name: getNameFromCommandLine() });

bot.registerActionHandler(({ foldAction, allInAction }) => {
    const gameState = bot.getGameState();
    const myCards = gameState.getMyCards();

    const jack = ranks.fromRankToNumber(ranks.jack);
    const first = ranks.fromRankToNumber(myCards[0].rank);
    const second = ranks.fromRankToNumber(myCards[1].rank);

    if (first >= jack && second >= jack) {
        return allInAction;
    }

    return foldAction;
});

bot.connect();

After the flop, is my full hand better than the community cards?

A bot that checks if your hand is better than the community cards i.e. does your hidden cards help to get a better hand.

During the pre flop, play somewhat cautiosly.

import { createBot, getNameFromCommandLine, evaluator, tableStates } from '@cygni/poker-client-api';

const bot = createBot({ name: getNameFromCommandLine() });

// During the pre flop, check, call or fold (in that order)
const handlePreFlop = ({ checkAction, callAction, foldAction }) => {
    return checkAction || callAction || foldAction;
};

// After the pre flop, raise or go all in when your combined hand ranks better than the community cards;
const handleEverythingAfterPreFlop = ({ raiseAction, foldAction, allInAction }) => {
    const gameState = bot.getGameState();
    const myCardsAndCommunityCards = gameState.getMyCardsAndCommunityCards();
    const communityCards = gameState.getCommunityCards();

    const myRanking = evaluator.evaluate(myCardsAndCommunityCards).ranking();
    const communityRanking = evaluator.evaluate(communityCards).ranking();

    if (myRanking > communityRanking) {
        return raiseAction || allInAction;
    }

    return foldAction;
};

bot.registerActionHandler(({ checkAction, callAction, raiseAction, foldAction, allInAction }) => {
    const gameState = bot.getGameState();

    if (gameState.getTableState() === tableStates.preflop) {
        return handlePreFlop({ checkAction, callAction, foldAction });
    }

    return handleEverythingAfterPreFlop({ raiseAction, foldAction, allInAction });
});

bot.connect();

Go all in if you have straight or better

A bot that checks if your hand has straight or higher, and in that case goes all in.

During the pre flop, follow if you have two cards higher than tens.

import { createBot, getNameFromCommandLine, evaluator, tableStates, ranks } from '@cygni/poker-client-api';

const bot = createBot({ name: getNameFromCommandLine() });

// During the pre flop - check/call when both cards are higher than 10
const handlePreFlop = ({ checkAction, callAction, foldAction }) => {
    const gameState = bot.getGameState();
    const myCards = gameState.getMyCards();

    const jack = ranks.fromRankToNumber(ranks.jack);
    const first = ranks.fromRankToNumber(myCards[0].rank);
    const second = ranks.fromRankToNumber(myCards[1].rank);

    if (first >= jack && second >= jack) {
        return checkAction || callAction || foldAction;
    }

    return foldAction;
};

// After the flop, go all in on straght or higher
const goAllInOnStraightOrHigher = ({ foldAction, allInAction }) => {
    const gameState = bot.getGameState();
    const myCardsAndCommunityCards = gameState.getMyCardsAndCommunityCards();
    const myRanking = evaluator.evaluate(myCardsAndCommunityCards).ranking();

    if (myRanking >= evaluator.hands.straight.ranking) {
        return allInAction;
    }

    return foldAction;
};

bot.registerActionHandler(({ checkAction, callAction, raiseAction, foldAction, allInAction }) => {
    const gameState = bot.getGameState();

    if (gameState.getTableState() === tableStates.preflop) {
        return handlePreFlop({ checkAction, callAction, foldAction });
    }

    return goAllInOnStraightOrHigher({
        checkAction,
        callAction,
        raiseAction,
        foldAction,
        allInAction,
    });
});

bot.connect();
