i dont like the turn check at all

4th spade falls, he bets, you punch yourself
4th spade falls, he checks, you bet, he check-raises, you punch yourself
4th spade falls, he checks, you check, he shows KQo no spades, you punch yourself

blank non-pairing falls, he bets, you call, he shows KQo you punch yourself
blank non-pairing falls, he bets, you raise, he pushes, you punch yourself
blank non-pairing falls, he checks, you bet, he check-raises, you punch yourself
blank non-pairing falls, he checks, you bet, he calls and shows KQo and you lose value

now think of this

you bet the turn, he check-raises, you can still call and stack him if it pairs, or get away cheaply if it doesnt

you bet the turn, he calls, youre in position to do whatever on the river - call a weak bet on a 4th spade, let it go to a strong bet on a 4th spade, or value bet a blank, or even check behind THEN rather than on the turn

def bet the turn
