If your opponent plays with 2 guards with limited shooting capacity but great playmaker abilities (pass/hand/drv) and strong inside players (SF/PF/C) they will take many inside shots, in this case 2-3 might help you to stop them and colect rebounds.
if they are outside oriented team, 3-2 or 1-3-1, 3-2 with help a bit more in defensive rebounds.
If his offensive flow is poor we may try also 3-2 to put pressure on their guards and force turnovers
As usual there's no general rule. Depends on your strenght and weakness and your opponent st/weak
