AA on a single-suit board

[kinboshi]

Playing 50p/£1 cash at DTD.  I've been getting a bad run of cards, and with some loose play at the table I've been struggling to find spots to win pots.  I'm sitting with a little over £100 (having replenished my stack), there are some smaller stacks and others with a little more than me.

Anyway, I'm in the BB and look down at  .

UTG+1 raises to £3 - a small raise for this table (loose aggressive player, but seems to understand the game, whereas some others at the table are just loose and bonkers).  One of the bonkers players calls, and when it comes round to me I raise to £12.

UTG+1 calls (he has about £80).  The other player folds.

Flop:   

The action's on me.  What should I be thinking here?  Should I be leading out?

I decided to bet, and made it £18.

The other player moves all-in.

What do I do here?

In that game I raise more pre.Its not as if you are going to lose both customers, usually in that game. £25 or so

then I bet more on the flop, say half the remaining stack in front of you

then your decision is made for you. takes away the "I don't want to get stacked, but I might be folding the best hand" type of conundrum you now face

as is, his range x, Qx etc as well as made flushes and sets etc is broad. You have to call

shove!

Raise more pre in live cash, people play so bad its like online cash in 2003!

Flop i like the weaker lead, open his range a bit more, then call

[fidget]

Preflop shout SQUEEEEEEZE then make it £20 with a naughty look on your face.
Then on flop get stacked and reload.
