I will be doing subsequent quick and dirty intermediate guides for all the match ups going forward. Let me know if you find this format and information level useful. Critique is welcome. S-Laughter has some decent advice I don’t have in here. Together I think they make a pretty comprehensive intermediate run down on this match up. Hope it helps.
What R.Mika fears about Nash:
Moonsault, Overhead, safe normals, V-Reversal and generally good escape capacity, ability to out footsie
Main Nash tactics:
Sonicbooms keep her from closing in safely, moonsaults keep pressure on fairly high, his crouching normals are safe enough that overhead is a good mix up, his v-reversal and unmatched walk and dash speed make him slippery as hell and keeping him in the corner a real cause for worry and consideration. His moves generally move him forward but push you away on block keeping you just in his optimal range for specials.
Be wary of Nashes that know their air to air. His ground game is strong and his air buttons will nearly always beat yours. Focus more on anti-airing and predicting/punishing his moonsaults.
His zoning pressure is combined with his ability to mix up with cross counters and teleports. His booms are set up tools as well as zoning tools. It is important to keep him from being too sonicboom happy. The only way to fix this is jump in heavy kick. Should you find yourself too far away from him, neutral jump his booms till he is forced to close in if you have a life lead, otherwise take the risk to get past them and be willing to block a few to get in a more optimal range where you can start preempting them with shooting peach. Staying at mid close range despite his fairly heavy pressure is key to this match up.
His overhead can cause you trouble if the pressure gets too high. Ex Peach can reset the pressure on block as a punish to this.
His wake up sucks, this is why its important to keep him as close as possible. Avoid moves that throw him too far away from you on knock down if you can.
There is nothing you can do about his escapes from the corner. Keep cool, block cross ups and be patient till you can switch things back into your favor with a throw/irish whip/wingless
Punish all ex sonic slices with crush counter combos if possible.
Match Up specific buttons:
Cr. HP, use this button to trade with sonic booms when you predict they will be coming but he is just out of range of your cr. HK. It is a good trade and keeps his moment from building.
Cr. HK, use this button to punish Nash’s at a fairly long distance, builds V meter
Match Up specific buttons to avoid:
Standing medium kick, this button is generally useless in this match up. It’s anti air properties aren’t useful for many of his jump ins unlike some other match ups, and it’s generally unsafe at the range it is best used in. Use sparingly.
Cr. medium kick, do not use this for anything other than sonicboom punishes. His cr. heavy buttons are better than your mediums and can crush counter you every time. At the least it is really blockable given his attack vectors and generally gets you nowhere. Again use sparingly. None of her buttons are bad if used as mix ups in this match up.
Match Up specific meter usage:
EX Peach takes precedent. You can use it to punish his over head on block. Use ex throws sparingly or when you have a lot of meter build up
