(US citizen) Wondering if i'll possibly have issues getting to thailand

I was in thailand for 86 days with visa extended from march till june 5th and have since been in malaysia.

My friends have planned a 4 day trip to krabi and I'm going but have only booked one way as im unsure if i'd like to go to somewhere like koh lipe or langkawi. Even though this trip wont last more than 10 days im wondering if I realistically could have problems and need to book a way out.

Thanks!

Iam now nearing the end of my extensiom after land border crossing, having previously been on TR60 with extension. I am wondering if i can do another border bounce to extend my stay? Or any other alternatives? Would it still be another 30 days with british passport?

Thanks

The 2 land border bounces that are 'allowed' in a year - that still true if I've had 2 TR visas (plus extensions) in the same year?
