3/6 top pair vs aggro tag, mebbe easy and standard

[Victor]

villain is 19/16 with 6 af. 11/18/6 by street. i have about 1k hands on him. we didnt tangle until these 2 hands.

we are both about 2 buyins deep. i raise in the sb with aq and he 3bets and i call. flop is kt4 with 2 d. i peel a potsize bet and hit j completing flush. turn is checked thru. river i check and call potsize bet and he was bluffing with 99. if this hand sucks go ahead and let me know.

but here is the main hand. eff stacks ~1k. so a few hands later (different table) he raises in the co and i 3bet with akh, he calls.

flop is k87 with 2d.

i bet 100 into 130 and he calls.

turn is 3 and puts 2 spades on board. check and he bets 305 and i call.

river is q completing spade backdoor flush.

i check and he bets like 596 into 900 pot.

edit to say he was allin on river.
