anxiety

Chess is a good ego checker for most people, you gotta realize your not ever gonna be the best and not let losses get you down. Especially losses that you knew you could win but mouseslipped, had a brain fart, or just throw away on accident. It happens and you just gotta laugh at it
Actually i didnt mean when losing. I meant when you start focusing and calculating as this is triggering stomach problems related to colon spasms

hmm.
yes. sort of.
there are situations where I feel anxious. on the flip hand there are times when I feel clever,delighted, and amazed.
do you feel anxious about chess, OP? if so you are not alone. on the other hand; to progress surely means getting it... your hardly playing your best if your all anxious. and that (playing as skillfully as you can ) IS the point of this hobby.

oh.
still I feel, moments of jitters. like when I begin in a tournament; or are playing blitz
and it feels like a stomache ache kind of feeling. the body is "expressing" what your feeling. its all very normal. kind of annoying. but possible to overcome. do more NOT less- and these kind of feelings will be less intense and uncomfortable. (I think)
*disclaimer, since I'm not a doctor its got to be said that there's possibly more to it than that. if you feel any pain,spasm,etc repeatably; perhaps its NOT just nerves.

Hello,

@mech.
sometimes I feel this too... espacially when something is new or when something usually doesn't go well.
for example G5!
I hate that time control-- I'm all but blind playing chess that fast and my stomach knows it!
surely working to mentally relax is great advice.

Interesting.
For me, chess is a form stress relief. It helps direct my focus away from things I don't need to be stressed over.
