Preflop I dont know SB could go bigger to be more polarized obv this size dont force out BB semi bluffs so it looks like SB have only value here
When the board comes top of SB range is QQ,and BB blocks that so BB knows that SB best hand here is AA KK and I guess he can bluff those off if some of the draws complite and SB have some hands that BB beat like AK maybe some 4bet bluffs.So call seems to be good option.Now Im not sure what BB range looks like in this spot QQ are there Idk if bb have 77 88 but he have 78s 9T 56s KQs QTs AQ 9J T9 of clubs
Turn-Kd-smash SB range so we need 24% of equity to make a call and against AK AA(which is big part of SBrange) we have 6 clean outs so about 12% of equity but if we can assume we will be pay on every sing of our outs we can make a call.If we add some bluffs like FD to SB range BB have to call he is only dead against KK and there still chance to fold SB if some draw gets there.
River-I cant figure out why SB bet AA here,I dont think he have enough bluffs in this spot to expect that BB will bluff catch with all 9x and Qx .I think SB should c/c to let BB bluff with draws.
But who knows I play nl10 so probably my analysis is quite primitive for this level
