It depends on how often he is stealing. If he doesn't steal often, I'll check how often he bets turn and flop so I can plan whether I want to float and steal on later streets. If he bets/folds a lot, my range is extremely loose and I'll call with connectors, suited gappers, Kxs, Axs, any PP with a plan of what I want to do on the turn or river. If he doesn't steal often but loves barreling, I'll tighten my range a bit and I might get sticky with TP depending on his bet sizes.
If he steals often, my range will be extremely loose also. Whether I 3bet or call will depend on his fold to 3bet percentage and fold to cbet percentage. I will get super sticky with my PP, TP and MP
hands depending on player type.
