this assumes that we wouldn't bluff at this checked flop with two spades (if we had some spades, say QT/QJs) to check back this flop as a lot of player seem to check these sorts of flops with B range Ax hands (A8/A9/AT etc) and we can apply a lot of pressure if we get favorable turn cards for our hand?

if opp has a tendency to fold except the very top of his range we could make it, say 112$ here
