For it to work like you're saying, a chain split has to happen

I didn't said you can create a chain split. I only said that you can use RBF on a tx that already have 1 confirmation (as OP asked). Chain split is another story.

Again you are trying to twist my words.

I am giving you a chance to clarify what you are talking about since the way you reply to 

 makes us believe you think we can use RBF to create a chain split which is simply not true.

If the RBF have a higher fee and a miner willing to take, it will replace the previous one.

>> I am a bit lost. Isn't RBF just for transactions waiting to be confirmed (mempool)? It doesn't work after the transaction is in a block, right?
