20-40 hand --- A-10 suited in the BB

Lucky Chances 20-40 last night. folded to solid MP, who opens. All fold to cut-off (another solid player) who raises. Button and small blind fold. I call in BB with A-10 diamonds. Flop is Ace-Q-5 with two diamonds. I check and MP checks. Cutoff bets, I raise, MP calls two bets cold, and cutoff calls. Turn is a 4. I bet, MP raises, cutoff folds and I call. River is a 10. Do I value bet two pair or check-call? Thanks.
