We got a bit stuck with a question and russian rules we got here doesnt seem to make it clear. If investigator during Arkham encounter phase draws 'a gate and monster apperars' card - he is immediately drawn through the gate and is delayed in 1st half of the Other World. He the gets his encounter there in Other Worlds encounters phase? In other words, investigators that drawn through gates have 3 Other worlds encounters instead of 2 normally. Am I right?

That is exactly right. Being delayed doesn't preclude your OW encounter.

so wait, if you get put in the OW by an encounter in the arkham encoutner phase you then also get an encounter in the OW encounter phase? didnt realise that.

Arkham Encounter and OW Encounter are different phases (#3 and #4). If you qualify for an encounter (that is, are located in Arkham or OW) when that phase rolls around, you'll have an encounter.

Thank you very much!
