After him checking twice, I think this is a good card to get some stronger PPs of his to fold (88-TT) .. im already planning to mostly barrel OTR (and stop on any non spade river, T/A), since he could be also floating with some AK here sometimes.

I probably figured ingame that he could also have some random lower SC or turned spades draw that we have beat and we have no need to bluff here with A high then. Its also not that favourable since we block some folding hands of his (AK, 99, T9) .. on the other hand, its probably still fine in a vacuum to continue betting here, as hes pretty capped with the previous action. The only benefit we have with this hand is blocking one AJs combo that might call our bet OTR. Other than that, I think this should be a half pot bet, seeing we should get so many folds and wed play any Qx/strong Jx the same way
