It seems a strange way for him to play his strong hands, especially as I would expect most Tx and all gutshots to bet the flop mostly so his value range is very thin. Ks might block some bluffs though.

I block T8 and 88, T9 I would expect to bet flop, QJ and 99 seem like strange hands to x/c the turn so I want to discount those, T2o folds pre usually and 22 usually wants to just value bet 3 streets.

I'm near the bottom of my value range so folding can't be exploitable when he overbets but it feels very suspicious.
