Regardless of whether they choose to change the pace of the game by time, number of hands played or for each round, the game is going to proceed in the order of H.O. R.S.E.

The individual strategies that you apply for each gaming variant when you play them as stand-alone game would definitely work as fine when you apply them in the round where that particular game played. Do not confuse thinking what you will do next for the next game when you are playing one variant per the HORSE poker rules.

Forget The Rest And Play The Existing Game And Strategy

Just play each round per the strategy for that particular game.  When over and started on with a new round, forget the other game and play by the strategy for that particular game in play for that round.  This is the only way to play the strategies right without confusing the goal.

Aggressive and Passive Strategies

A good idea is to play those games you are good in by applying aggressive strategies and to play passively in those gaming variant rounds for which you are weak.

H.O.R.S.E poker can seem intimidating

Each game might show up with different situations for gaming.  Unless you have played each of the individual games in different lights of competitors and betting limits, H.O.R.S.E poker can seem intimidating.

Fixed Limit HORSE poker

Despite there being poker rooms offering pot limit and no limit HORSE poker games, you get more than the required excitement from the change gears of games in a basic limit game.  Even with expert skills, you will feel challenged with a Fixed Limit Horse poker game.

Like any other poker game, starting hand selection is crucial in this variant of poker too. If you are tolerant to change and if you have enough experience in the five games in this play, you should try to HORSE.
