88 in BB against two total crazy LAGs

[imported_PP123]

MP2 is a total maniac preflop. He's the most crazy player I've ever played with in a live game. He plays about 2/3 of all hands hand raises 50% of them. He doesn't bother about position and how the action has been in front of him. He frequently raises and reraises with hands like Q6o, 53o, J5o and so on. Post-flop he usually calms down a bit, but still is quite aggressive. He frequently calls the flop with nothing and usually goes to showdown if he catches anything. His fearless play has so far made him a big winner. He has won some very big pots by sucking out.

SB is a hyper aggressive maniac preflop too, but less aggressive than MP2. He complains all the time about how bad MP2 plays and often 3-bets him. He calls a lot of MP2's preflop raises och 3-bets his 'better hands' like Q8o, A7o, 75s. Postflop he calms down too, but he's very aggressive with his big cards hands like AK, AQ etc. He has capped the flop and turn a few times with just a gutshot and an overcard. But a few times he has check fold the flop against a field with pocket pair like JJ when an Ace flopped. One important thing is that he respects my play. He says he respect me and that I'm a good player. In the hands we have played with each other he has respected my bets and raises.

What do you think about my preflop play? Should I have capped or maybe just called planning on raising more or less every flop. I should mention that I didnt cap to get rid of MP2. There were absolutely no chance that MP2 would fold for two more bets. My second question is what you think about my flop/turn play. What would my plan be if a blank hit on turn?

Edit: MP2 folded the turn.
