Against Thawk, I’ve had some success against the Hawk dive like this:
neutral jump or jump back (range dependent), and roundhouse drill it. if he whiffs, he has a significant recovery time – it’s only if you block it that he is safe.
With Honda, I suggest getting yourself into a 2 player room and going at it with a Honda player for a long time. that’s the only way to learn this matchup.
My experience however is that you need to categorize your opponent a little. Honda is dangerous to Dhalsim for a number of reasons. Buttspam, hhs spam, tick oichyo spam, headbutt spam, etc, all dangerous.
Most players fall into two categories: Buttspam crossups v. Oichyo spam. There are two subtypes - headbutt subtype or hhs subtype, it feels like. Like, most players will either do buttspam crossups into headbutt attempts, or hhs attempts. Or they will do jumpin oichyo spam into either headbutt combos or hhs attempts.
This matchup is a sadly a lot about knowing the player, since if you spend your entire match planning for him to either hundred hand slap or buttbomb or headbutt simultaneously, you are going to not be able to do anything except db.jab, or fireball if you’re at full screen.
In a tournament setting this would make it very very hard. What I would recommend is, turtling down for a little bit and trying to get a feel for him.
The most important thing in this matchup is to WAIT. A lot of your antiairs and punishment moves will just not work unless you wait patiently for the right moment. For example:
The buttbomb is the biggest problem I have personally had. Like, I throw a fireball, then I see a buttbomb, and I immediately want to throw a fierce to make him land on it, or a cr.mp or similar. You can’t do this. You’ve got to wait until he lands and whack him before he recovers, otherwise you lose a nasty trade.
Lots of his jumping attacks are similar. You’ve got to either punish when he lands, or hit him before or after the move comes out. His jump roundhouse is super hard to deal with.
If you play dhalsim well, it is best to just be prepared to play Honda, because that’s the #1 scrub counterpick for Dhalsim. #2 is chun, #3 is claw, and #4 is blanka. I always expect my opp. to pick one of these characters after I romp their main a few times.
