    Position guide

    PositionAction
    UTGFold. 43o UTG facing many players yet to act, difficult to form a strong made hand postflop, and easily re-raised, should fold 100%.
    MPThere are still many players behind in MP position. 43o lacks playability. Unless you have a special read, just fold.
    CO5BB if the blinds are tight. 43o has some blind-stealing value in CO, but be cautious post-flop, avoid big pots.
    BTN5BB if the blinds defend weakly. 43o has positional advantage on the BTN, can steal blinds, but should continue betting on dry low boards post-flop.
    SBFold or very occasionally raise. SB position is unfavorable post-flop, and 43o is not suitable against the big blind's wide range unless the opponent has a high fold rate.
    BB43o in BB has pot odds, and post-flop you can use straight draws to bluff.

    Postflop board textures

    g. 7♣2♦9♠

    Can continue betting representing a strong hand. 43o has a small amount of showdown value on a dry board, but it is better used as a bluff, betting 2/3 of the pot to force high cards to fold.

    Hand board label: 43o Wet connected board e.g. 9♠8♠7♥

    Usually check-fold. 43o on wet boards is easily overtaken by opponents' draws, and its own draw is weak. Unless it has bottom pair or a gutshot, fold.

    g. K♠K♦7♣

    Check-fold. 43o has almost no value on the board; the opponent is ahead when holding a K or a pocket pair, and bluffing is also difficult to succeed.

    g. A♠8♠3♠

    Check and fold. 43o has no flush draw and is easily dominated by flushes or overpairs. Unless there is a gutshot straight draw, fold directly.

    Specific matchup notes

    Against AK 43%, 43o needs to apply pressure on low boards to avoid AK hitting top pair. Against small pairs like 88 54%, 43o has a slight edge because 88 struggles to make strong hands on low boards. Against suited connectors like 76s, 43o leads on dry boards but is at a disadvantage on wet boards. Key: Avoid big pots, use position and board texture.

    MTT short-stack push/fold

    15BB: Only push all-in from BTN, fold from other positions. 20BB: Almost never push, unless opponent is extremely tight and you have a good read. In summary, 43o is suitable for stealing blinds when short-stacked, but avoid against calling stations.
