When sparring I tend to counter either off feints or pressuring to promote a response, so i don't really throw hard, just hard enough to let my partner know I tagged them. If i counter with combos I do so explosively and usually catch them with one or two shots. I find that some guys will eventually just start throwing super hard after I tag them a few times. Is this because the counters are hitting harder than I expect and they are trying to match me? or is it more of an ego thing and i should just pick better partners?
