1) never raising this out of the BB, unopened to me on the button then yes. Like Alex I'm only ever raising live limpets (new word for limpers
) with KJ+
2) you're always beat, the reg you describes wouldn't be a winning player if he's making a ridiculous overbet like this without the 5 high flush beat. Even if on the 1% chance you're not beat there's a lot better spots to get money in, let him have your £7 and get it back later.
Lead the flop, you have ridic equity and are building a bigger pot for yourself if you catch an offsuit 4 or your flush draw is live.
Worse I bet call with OTR?
would have me sweating on the wrong side of call probably, even though personally I think this is a boat raising to get a flush to punch a ticket to valuetown. Personally I think this is 22 or 66,
