You block a lot of his bluffs.
Do you have any good reads to make you want to continue in this hand? Has he been raising flops a lot?
Most times @ 1/2 live this will be value, I don't he's doing it with AQ for example with this sizing. Having is pretty crucial.
His value range is JJ, 55, AJ, A5. Toiling to find a lot of bluffs, could see 10qhh been played this way but not a lot of other hands.
