this board should be divided into real hand analysis and 50p whining tales.

The only mistake i think i made was i that i should've raised more preflop probably to to 2.5k or thereabouts.
No! Raise size is good, you want people in the pot you have the 4th best hand in the game.
id make it 2400 when your raising in this spot you don't always want a call. if you raise to 2000 with the 4th best hand and better, then raise a different amount with worse hands you may give your hand range away.
