If opponent is bigger...there streght/power/ technique leve, agility, mobility and speed should be taken in account. + skills level he does have.
In smaller circles ppl does know enough about possible opponents. Large cricles; it is different world.
If he is larger and heavier but not stronger than you, is slower than you and doesn't have tech advantage?
Then brutal power game might work well and surprise him a lot.
If he is larger and stronger ....usually flowchart is to provoke him to do certain striking / grappling attacks and catch him in trap with prepared counter technique...
If this is for SD not sport...if he is heavier and larger...dirty stuff usually is used......
I don't advise to spar with not normal ppl who are larger and stronger than you, doesn't have some other predictable disatvantages.
For boxing some from most effective methods are different;
to provoke him execute straight power punch and counter this. If well done, effect might be devastating.
The same with provocations attempt to do power hooks.
Ofc then lad should have...some real advantages vs bigger guy in technique, speed etc.
For grappling well works provocations to attempt do throws, foot sweeps.
KB: for me best working stuff was provoke them to do head kicks... this ofc is individual thing here.
These bigger stronger guys too are different: some might be effective in short distance, some are effective only if they does have really a lot of space to move and distance to generate power.
Some...might be terrible opponents even if they doesn't punch or kick, just are holding you for example....
